scope\n// - Socket (CPU package) scope\n// - MemoryDomain (NUMA domain) scope\n// - Node (full system) scope\n//\n// Transformations follow these rules:\n// - Same scope: Return data as-is (e.g., Core → Core)\n// - Coarser scope: Aggregate data (e.g., Core → Socket with Aggregate=true)\n// - Finer scope: Error - cannot increase granularity\n//\n// # Query Building\n//\n// buildQueries and buildNodeQueries are the main entry points, handling job-specific\n// and node-specific query construction respectively. They:\n// - Validate metric configurations\n// - Handle subcluster-specific metric filtering\n// - Detect and skip duplicate scope requests\n// - Call buildScopeQueries for each metric/scope/host

metricstoreclient provides a client for querying the cc-metric-store time series database.\n//\n// The cc-metric-store is a high-performance time series database optimized for HPC metric data.\n// This client handles HTTP communication, query construction, scope transformations, and data retrieval\n// for job and node metrics across different metric scopes (node, socket, core, hwthread, accelerator).\n//\n// # Architecture\n//\n// The package is split into two main components:\n// - Client Operations (cc-metric-store.go): HTTP client, request handling, data loading methods\n// - Query Building (cc-metric-store-queries.go): Query construction and scope transformation logic\n//\n// # Basic Usage\n//\n//\tstore := NewCCMetricStore(\"http://localhost:8080\",

client supports hierarchical metric scopes that map to HPC hardware topology:\n// - MetricScopeAccelerator: GPU/accelerator level metrics\n// - MetricScopeHWThread: Hardware thread (SMT) level metrics\n// - MetricScopeCore: CPU core level metrics\n// - MetricScopeSocket: CPU socket level metrics\n// - MetricScopeMemoryDomain: NUMA domain level metrics\n// - MetricScopeNode: Full node level metrics\n//\n// The client automatically handles scope transformations, aggregating finer-grained metrics\n// to coarser scopes when needed (e.g., aggregating core metrics to socket level).\n//\n// # Error Handling\n//\n// The client supports partial errors - if some queries fail, it returns both the successful\n// data and an error listing the failed queries. This allows processing partial results\n// when some nodes or metrics are temporarily unavailable.\n//\n// # API Versioning\n//\n// The client uses cc-metric-store API v2, which includes support for:\n// - Data resampling for bandwidth optimization\n// - Multi-scope queries in a single request\n// - Aggregation across hardware topology levels\npackage metricstoreclient\n\nimport

Socket with Aggregate=true)\n// - Finer scope: Error - cannot increase granularity\n//\n// # Query Building\n//\n// buildQueries and buildNodeQueries are the main entry points, handling

system) scope\n//\n// Transformations follow these rules:\n// - Same scope: Return data as-is (e.g., Core → Core)\n// - Coarser scope: Aggregate data (e.g., Core → Socket with Aggregate=true)\n// - Finer scope: Error - cannot increase granularity\n//\n// # Query Building\n//\n// buildQueries and buildNodeQueries are the main entry points, handling job-specific\n// and node-specific query

Transformations\n//\n// The buildScopeQueries function implements the core scope transformation algorithm.\n// It handles 25+ different transformation cases, mapping between:\n// - Accelerator (GPU) scope\n// - HWThread (hardware thread/SMT) scope\n// - Core (CPU core) scope\n// - Socket (CPU package) scope\n// - MemoryDomain (NUMA domain) scope\n// - Node (full system) scope\n//\n// Transformations follow these rules:\n// - Same scope: Return data as-is (e.g., Core → Core)\n// - Coarser scope: Aggregate data (e.g., Core → Socket with Aggregate=true)\n// - Finer scope: Error - cannot increase granularity\n//\n// # Query Building\n//\n// buildQueries and buildNodeQueries are the main entry points, handling job-specific\n// and node-specific query construction respectively.

metric scopes and native hardware topology,\n// automatically aggregating or filtering metrics as needed.\n//\n// # Scope Transformations\n//\n// The buildScopeQueries function implements the core scope transformation algorithm.\n// It handles 25+ different transformation cases, mapping between:\n// - Accelerator (GPU) scope\n// - HWThread (hardware thread/SMT) scope\n// - Core (CPU core) scope\n// - Socket (CPU package) scope\n// - MemoryDomain (NUMA domain) scope\n// - Node (full system) scope\n//\n// Transformations follow these rules:\n// - Same scope: Return data as-is (e.g., Core → Core)\n// - Coarser scope: Aggregate data (e.g., Core → Socket with Aggregate=true)\n// - Finer scope: Error - cannot increase granularity\n//\n// # Query Building\n//\n// buildQueries and buildNodeQueries are the main entry points, handling job-specific\n// and node-specific query construction respectively. They:\n// - Validate metric configurations\n// - Handle subcluster-specific metric filtering\n// - Detect and skip duplicate scope requests\n// - Call buildScopeQueries for each metric/scope/host combination\npackage metricstoreclient\n\nimport (\n\t\"fmt\"\n\n\t\"github.com/ClusterCockpit/cc-backend/pkg/archive\"\n\t\"github.com/ClusterCockpit/cc-backend/pkg/metricstore\"\n\tcclog

metrics, scopes, and job resources to build the complete query set.\n//\n// The function handles:\n// - Metric configuration validation and subcluster filtering\n// - Scope deduplication to avoid redundant queries\n// - Hardware thread list resolution (job-allocated vs full node)\n// - Delegation to buildScopeQueries for scope transformations\n//\n// Returns queries and their corresponding

high-performance time series database optimized for HPC metric data.\n// This client handles HTTP communication, query construction, scope transformations, and data retrieval\n// for job and node metrics across different metric scopes (node, socket, core, hwthread, accelerator).\n//\n// # Architecture\n//\n// The package is split into two main components:\n// - Client Operations (cc-metric-store.go): HTTP client, request handling, data loading methods\n// - Query Building (cc-metric-store-queries.go): Query construction and scope transformation logic\n//\n// # Basic Usage\n//\n//\tstore := NewCCMetricStore(\"http://localhost:8080\", \"jwt-token\")\n//\n//\t// Load job data\n//\tjobData, err := store.LoadData(job, metrics, scopes, ctx, resolution)\n//\tif err !=

metrics\n// - MetricScopeHWThread: Hardware thread (SMT) level metrics\n// - MetricScopeCore: CPU core level metrics\n// - MetricScopeSocket: CPU socket level metrics\n// - MetricScopeMemoryDomain: NUMA domain level metrics\n// - MetricScopeNode: Full node level metrics\n//\n// The client automatically handles scope transformations, aggregating finer-grained metrics\n// to coarser scopes when needed (e.g., aggregating core metrics to socket level).\n//\n// # Error Handling\n//\n// The client supports partial errors - if some queries fail, it returns both the successful\n// data and an error listing the failed queries. This allows processing partial results\n// when some nodes or metrics are temporarily unavailable.\n//\n// # API Versioning\n//\n// The client uses cc-metric-store API v2, which includes support for:\n// - Data resampling for bandwidth optimization\n// - Multi-scope queries in a single request\n// - Aggregation across hardware topology levels\npackage metricstoreclient\n\nimport

cc-metric-store time series database.\n//\n// The cc-metric-store is a high-performance time series database optimized for HPC metric data.\n// This client handles HTTP communication, query construction, scope transformations, and data retrieval\n// for job and node metrics across different metric scopes (node, socket, core, hwthread, accelerator).\n//\n// # Architecture\n//\n// The package is split into two main components:\n// - Client Operations (cc-metric-store.go): HTTP client, request handling, data loading methods\n// - Query Building (cc-metric-store-queries.go): Query construction and scope transformation logic\n//\n// # Basic Usage\n//\n//\tstore := NewCCMetricStore(\"http://localhost:8080\", \"jwt-token\")\n//\n//\t// Load job data\n//\tjobData, err := store.LoadData(job, metrics, scopes, ctx, resolution)\n//\tif err != nil {\n//\t log.Fatal(err)\n//\t}\n//\n// # Metric Scopes\n//\n// The client supports hierarchical metric scopes that map to HPC hardware topology:\n// - MetricScopeAccelerator: GPU/accelerator level metrics\n// - MetricScopeHWThread: Hardware thread (SMT) level metrics\n// - MetricScopeCore: CPU core level metrics\n// - MetricScopeSocket: CPU socket level metrics\n// - MetricScopeMemoryDomain: NUMA domain level metrics\n// - MetricScopeNode: Full node level metrics\n//\n// The client automatically handles scope transformations, aggregating finer-grained metrics\n// to coarser scopes when needed (e.g., aggregating core metrics to socket level).\n//\n// # Error Handling\n//\n// The client supports partial errors - if some queries fail, it returns both the successful\n// data and an error listing the failed queries. This allows processing partial results\n// when some nodes or metrics are temporarily unavailable.\n//\n// # API Versioning\n//\n// The client uses cc-metric-store API v2, which includes support for:\n// - Data resampling for bandwidth optimization\n// - Multi-scope queries in a single request\n// - Aggregation across hardware topology levels\npackage metricstoreclient\n\nimport

Returns empty slice for expected exceptions, error for unhandled cases +- **Scope string constants** — `HWThreadString`, `CoreString`, `MemoryDomainString`, `SocketString`, `AcceleratorString` (exported, move from both packages) +- **`IntToStringSlice()`** — exported, using the optimized buffer-reuse version from metricstore +- **`SanitizeStats(avg, min, max *schema.Float)`** — exported, using the metricstoreclient behavior (zero ALL if ANY is NaN) + +### 2. Update `pkg/metricstore/query.go` + +- Replace inline if-chain in `buildQueries()` (lines 317-534) with call to `BuildScopeQueries()`, converting each `ScopeQueryResult` → local `APIQuery` (adding `Resolution`) +- Replace inline if-chain in `buildNodeQueries()` (lines 1099-1316) with same pattern +- Delete local scope string constants, `intToStringSlice`, local `sanitizeStats` +- Update `sanitizeStats` calls in `LoadData`/`LoadScopedStats`/`LoadNodeData`/`LoadNodeListData` to use `SanitizeStats(&res.Avg, &res.Min, &res.Max)` +- Switch scope dedup from `map[schema.MetricScope]bool` to labeled-loop + slice (matches metricstoreclient, avoids allocation for typical 1-3 scopes) +- This **adds the missing MemoryDomain → Socket transformation** to the internal store + +### 3. Update `internal/metricstoreclient/cc-metric-store-queries.go` + +- Replace call to local `buildScopeQueries()` with `metricstore.BuildScopeQueries()`, converting each `ScopeQueryResult` → local `APIQuery` (adding `Resolution`) +- Delete local `buildScopeQueries()` function +- Delete local scope string constants and `intToStringSlice` +- Update `sanitizeStats` in `cc-metric-store.go` to call `metricstore.SanitizeStats()` + +### 4. Add tests: `pkg/metricstore/scopequery_test.go` + +Table-driven tests for `BuildScopeQueries` covering all transformation cases: +- Same-scope (HWThread→HWThread, Core→Core, Socket→Socket, Node→Node, etc.) +- Aggregation (HWThread→Core, HWThread→Socket, HWThread→Node, Core→Socket, Core→Node, etc.) +- Accelerator cases (Accelerator→Accelerator, Accelerator→Node) +- MemoryDomain cases including MemoryDomain→Socket +- Unhandled case returns error + +## Files Modified + +| File | Action | +|------|--------| +| `pkg/metricstore/scopequery.go` | **New** — shared types and functions | +| `pkg/metricstore/scopequery_test.go` | **New** — tests for BuildScopeQueries | +| `pkg/metricstore/query.go` | Refactor buildQueries/buildNodeQueries to use BuildScopeQueries; remove duplicated helpers | +| `internal/metricstoreclient/cc-metric-store-queries.go` | Replace local buildScopeQueries with shared; remove duplicated helpers | +| `internal/metricstoreclient/cc-metric-store.go` | Update sanitizeStats to use shared SanitizeStats | + +## What is NOT shared (intentionally) + +- **`APIQuery`/`APIMetricData` types** — different Resolution types, Data types, ScaleFactor field +- **`buildQueries`/`buildNodeQueries` themselves** — different topology access (caching vs inline), different receiver types +- **Load* result-processing functions** — depend on package-specific types and fetch mechanisms + +## Verification + +1. `go build ./...` — compile check +2. `go test ./pkg/metricstore/...` — existing + new scopequery tests +3. `go test ./internal/metricstoreclient/...` — compile check +4. `make test` — full test suite + + +If you need specific details from before exiting plan mode (like exact code snippets, error messages, or content you generated), read the full transcript at: /Users/jan/.claude/projects/-Users-jan-prg-ClusterCockpit-cc-backend/eec1fc87-d8f6-42f6-b296-d7a2f79af002.jsonl \ No newline at end of file diff --git a/fc/3be444ef4c/metadata.json b/fc/3be444ef4c/metadata.json new file mode 100644 index 00000000..572a3110 --- /dev/null +++ b/fc/3be444ef4c/metadata.json @@ -0,0 +1,31 @@ +{ + "cli_version": "0.4.9", + "checkpoint_id": "fc3be444ef4c", + "strategy": "manual-commit", + "branch": "dev", + "checkpoints_count": 1, + "files_touched": [ + "internal/metricstoreclient/cc-metric-store-queries.go", + "internal/metricstoreclient/cc-metric-store.go", + "pkg/metricstore/metricstore.go", + "pkg/metricstore/query.go", + "pkg/metricstore/scopequery.go", + "pkg/metricstore/scopequery_test.go" + ], + "sessions": [ + { + "metadata": "/fc/3be444ef4c/0/metadata.json", + "transcript": "/fc/3be444ef4c/0/full.jsonl", + "context": "/fc/3be444ef4c/0/context.md", + "content_hash": "/fc/3be444ef4c/0/content_hash.txt", + "prompt": "/fc/3be444ef4c/0/prompt.txt" + } + ], + "token_usage": { + "input_tokens": 53, + "cache_creation_tokens": 78269, + "cache_read_tokens": 3968698, + "output_tokens": 26118, + "api_call_count": 51 + } +} From 3674d93facb03d3df1b6da97828afbd8b8dab525 Mon Sep 17 00:00:00 2001 From: Jan Eitzinger Date: Wed, 4 Mar 2026 16:43:19 +0100 Subject: [PATCH 02/44] Checkpoint: fc3be444ef4c Entire-Session: eec1fc87-d8f6-42f6-b296-d7a2f79af002 Entire-Strategy: manual-commit Entire-Agent: Claude Code Ephemeral-branch: entire/9672903-e3b0c4 --- fc/3be444ef4c/1/content_hash.txt | 1 + fc/3be444ef4c/1/context.md | 12 +++ fc/3be444ef4c/1/full.jsonl | 162 +++++++++++++++++++++++++++++++ fc/3be444ef4c/1/metadata.json | 30 ++++++ fc/3be444ef4c/1/prompt.txt | 5 + fc/3be444ef4c/metadata.json | 17 +++- 6 files changed, 222 insertions(+), 5 deletions(-) create mode 100644 fc/3be444ef4c/1/content_hash.txt create mode 100644 fc/3be444ef4c/1/context.md create mode 100644 fc/3be444ef4c/1/full.jsonl create mode 100644 fc/3be444ef4c/1/metadata.json create mode 100644 fc/3be444ef4c/1/prompt.txt diff --git a/fc/3be444ef4c/1/content_hash.txt b/fc/3be444ef4c/1/content_hash.txt new file mode 100644 index 00000000..148bc0f4 --- /dev/null +++ b/fc/3be444ef4c/1/content_hash.txt @@ -0,0 +1 @@ +sha256:1669b15394a41801d8e26f8152b5005cd1c51b5d6d7c7e3ed5c187f6fdbeca6d \ No newline at end of file diff --git a/fc/3be444ef4c/1/context.md b/fc/3be444ef4c/1/context.md new file mode 100644 index 00000000..2853120c --- /dev/null +++ b/fc/3be444ef4c/1/context.md @@ -0,0 +1,12 @@ +# Session Context + +## User Prompts + +### Prompt 1 + +The buildQueries logic on @pkg/metricstore/query.go is diverged from the buildQueries logic in @internal/metricstoreclient/cc-metric-store-queries.go .

Now I have all the information needed. Let me provide a comprehensive report.\n\n## Summary: Shared Interface & Implementation Pattern\n\nI've found the complete picture of how the two metric store implementations work together. Here are the key findings:\n\n### 1. **Shared Interface: `MetricDataRepository`**\n\n**Location:** `/Users/jan/prg/ClusterCockpit/cc-backend/internal/metricdispatch/metricdata.go` (lines 21-60)\n\nThis is the central interface that both implementations must satisfy:\n\n```go\ntype MetricDataRepository interface {\n\t// Load job metric data with specified metrics and scopes\n\tLoadData(job *schema.Job,\n\t\tmetrics []string,\n\t\tscopes []schema.MetricScope,\n\t\tctx context.Context,\n\t\tresolution int) (schema.JobData, error)\n\n\t// Load node-scope statistics only (faster than LoadData)\n\tLoadStats(job *schema.Job,\n\t\tmetrics []string,\n\t\tctx context.Context) (map[string]map[string]schema.MetricStatistics, error)\n\n\t// Load statistics across multiple scopes\n\tLoadScopedStats(job *schema.Job,\n\t\tmetrics []string,\n\t\tscopes []schema.MetricScope,\n\t\tctx context.Context) (schema.ScopedJobStats, error)\n\n\t// Load current metric data for specified nodes (systems view)\n\tLoadNodeData(cluster string,\n\t\tmetrics, nodes []string,\n\t\tscopes []schema.MetricScope,\n\t\tfrom, to time.Time,\n\t\tctx context.Context) (map[string]map[string][]*schema.JobMetric, error)\n\n\t// Load paginated node list data with scope organization\n\tLoadNodeListData(cluster, subCluster string,\n\t\tnodes []string,\n\t\tmetrics []string,\n\t\tscopes []schema.MetricScope,\n\t\tresolution int,\n\t\tfrom, to time.Time,\n\t\tctx context.Context) (map[string]schema.JobData, error)\n\n\t// Health check for cluster monitoring state\n\tHealthCheck(cluster string,\n\t\tnodes []string,\n\t\tmetrics []string) (map[string]metricstore.HealthCheckResult, error)\n}\n```\n\n### 2. **Implementation 1: Internal Metric Store**\n\n**Location:** `/Users/jan/prg/ClusterCockpit/cc-backend/pkg/metricstore/query.go` (lines 41-50)\n\n```go\ntype InternalMetricStore struct{}\n\nvar MetricStoreHandle *InternalMetricStore\n\n// Implements all MetricDataRepository methods\nfunc (ccms *InternalMetricStore) LoadData(...) (schema.JobData, error)\nfunc (ccms *InternalMetricStore) LoadStats(...) (map[string]map[string]schema.MetricStatistics, error)\n// ... and others\n```\n\n**Key file:** `/Users/jan/prg/ClusterCockpit/cc-backend/pkg/metricstore/query.go` contains all method implementations for `InternalMetricStore`\n\n### 3. **Implementation 2: External CC-Metric-Store Client**\n\n**Location:** `/Users/jan/prg/ClusterCockpit/cc-backend/internal/metricstoreclient/cc-metric-store.go` (lines 71-79)\n\n```go\ntype CCMetricStore struct {\n\tclient http.Client\n\tjwt string\n\turl string\n\tqueryEndpoint string\n\ttopologyCache map[string]*schema.Topology\n}\n\n// Implements all MetricDataRepository methods\nfunc (ccms *CCMetricStore) LoadData(...) (schema.JobData, error)\nfunc (ccms *CCMetricStore) LoadStats(...) (map[string]map[string]schema.MetricStatistics, error)\n// ... and others\n```\n\n### 4. **Shared Types - `APIQuery` & `APIMetricData`**\n\nBoth packages define their **own copies** of these types (NOT shared):\n\n**In `pkg/metricstore/api.go` (lines 74-93):**\n```go\ntype APIQuery struct {\n\tType *string `json:\"type,omitempty\"`\n\tSubType *string `json:\"subtype,omitempty\"`\n\tMetric string `json:\"metric\"`\n\tHostname string `json:\"host\"`\n\tResolution int64 `json:\"resolution\"`\n\tTypeIds []string `json:\"type-ids,omitempty\"`\n\tSubTypeIds []string `json:\"subtype-ids,omitempty\"`\n\tScaleFactor schema.Float `json:\"scale-by,omitempty\"`\n\tAggregate bool `json:\"aggreg\"`\n}\n```\n\n**In `internal/metricstoreclient/cc-metric-store.go` (lines 93-104):**\n```go\ntype APIQuery struct {\n\tType *string `json:\"type,omitempty\"`\n\tSubType *string `json:\"subtype,omitempty\"`\n\tMetric string `json:\"metric\"`\n\tHostname string `json:\"host\"`\n\tResolution int `json:\"resolution\"`\n\tTypeIds []string `json:\"type-ids,omitempty\"`\n\tSubTypeIds []string `json:\"subtype-ids,omitempty\"`\n\tAggregate bool `json:\"aggreg\"`\n}\n```\n\n**Note:** These are separate definitions (not shared) - they're almost identical but used independently by each package.\n\n### 5. **Registration/Initialization**\n\n**Location:** `/Users/jan/prg/ClusterCockpit/cc-backend/cmd/cc-backend/main.go` (lines 320-346)\n\n```go\n// Initialize internal metric store\nmscfg := ccconf.GetPackageConfig(\"metric-store\")\nif mscfg != nil {\n\tmetricstore.Init(mscfg, metrics, &wg)\n\tms := metricstore.GetMemoryStore()\n\tjobRepo := repository.GetJobRepository()\n\tms.SetNodeProvider(jobRepo)\n\tmetricstore.MetricStoreHandle = &metricstore.InternalMetricStore{}\n\thaveMetricstore = true\n}\n\n// Initialize external metric store clients\nmscfg = ccconf.GetPackageConfig(\"metric-store-external\")\nif mscfg != nil {\n\terr := metricdispatch.Init(mscfg)\n\t// ...\n}\n```\n\n### 6. **Runtime Selection via `metricdispatch`**\n\n**Location:** `/Users/jan/prg/ClusterCockpit/cc-backend/internal/metricdispatch/metricdata.go` (lines 92-117)\n\nThe `GetMetricDataRepo()` function returns the appropriate implementation based on cluster/subcluster configuration:\n\n```go\nvar metricDataRepos map[string]MetricDataRepository = map[string]MetricDataRepository{}\n\nfunc GetMetricDataRepo(cluster string, subcluster string) (MetricDataRepository, error) {\n\t// Fallback chain:\n\t// 1. Try cluster + subcluster config\n\t// 2. Try cluster config only\n\t// 3. Try wildcard config\n\t// 4. Fall back to internal metric store (if available)\n\t// 5. Return error if none found\n\t\n\tif !ok && metricstore.MetricStoreHandle == nil {\n\t\treturn nil, fmt.Errorf(\"[METRICDISPATCH]> no metric data repository configured\")\n\t}\n\trepo = metricstore.MetricStoreHandle // Use internal as fallback\n}\n```\n\n### Key Architecture Points\n\n1. **Single Interface, Multiple Implementations:** The `MetricDataRepository` interface in `metricdispatch` is the bridge\n2. **Independent Type Definitions:** Each package defines its own `APIQuery` type for internal use\n3. **Dispatcher Pattern:** `internal/metricdispatch` acts as a registry and selector\n4. **Fallback to Internal:** If no external metric store is configured, falls back to `MetricStoreHandle`\n5. **No Shared Types Package:** There's no common `types.go` file - each package is self-contained and defines what it needs\n\n**Files involved:**\n- `/Users/jan/prg/ClusterCockpit/cc-backend/internal/metricdispatch/metricdata.go` — Interface definition and registry\n- `/Users/jan/prg/ClusterCockpit/cc-backend/pkg/metricstore/query.go` — Internal implementation\n- `/Users/jan/prg/ClusterCockpit/cc-backend/internal/metricstoreclient/cc-metric-store.go` — External client implementation\n- `/Users/jan/prg/ClusterCockpit/cc-backend/cmd/cc-backend/main.go` — Initialization"},{"type":"text","text":"agentId: ae13c6665fcb142fa (for resuming to continue this agent's work if needed)\ntotal_tokens: 46619\ntool_uses: 21\nduration_ms: 38792"}]}]},"uuid":"59b93734-24f6-4e65-b55a-b6ab85e03e83","timestamp":"2026-03-04T15:24:33.066Z","toolUseResult":{"status":"completed","prompt":"Find the MetricDataRepository interface or similar interface that both pkg/metricstore and internal/metricstoreclient implement.

Here are the key findings:\n\n### 1. **Shared Interface: `MetricDataRepository`**\n\n**Location:** `/Users/jan/prg/ClusterCockpit/cc-backend/internal/metricdispatch/metricdata.go` (lines 21-60)\n\nThis is the central interface that both implementations must satisfy:\n\n```go\ntype MetricDataRepository interface {\n\t// Load job metric data with specified metrics and scopes\n\tLoadData(job *schema.Job,\n\t\tmetrics []string,\n\t\tscopes []schema.MetricScope,\n\t\tctx context.Context,\n\t\tresolution int) (schema.JobData, error)\n\n\t// Load node-scope statistics only (faster than LoadData)\n\tLoadStats(job *schema.Job,\n\t\tmetrics []string,\n\t\tctx context.Context) (map[string]map[string]schema.MetricStatistics, error)\n\n\t// Load statistics across multiple scopes\n\tLoadScopedStats(job *schema.Job,\n\t\tmetrics []string,\n\t\tscopes []schema.MetricScope,\n\t\tctx context.Context) (schema.ScopedJobStats, error)\n\n\t// Load current metric data for specified nodes (systems view)\n\tLoadNodeData(cluster string,\n\t\tmetrics, nodes []string,\n\t\tscopes []schema.MetricScope,\n\t\tfrom, to time.Time,\n\t\tctx context.Context) (map[string]map[string][]*schema.JobMetric, error)\n\n\t// Load paginated node list data with scope organization\n\tLoadNodeListData(cluster, subCluster string,\n\t\tnodes []string,\n\t\tmetrics []string,\n\t\tscopes []schema.MetricScope,\n\t\tresolution int,\n\t\tfrom, to time.Time,\n\t\tctx context.Context) (map[string]schema.JobData, error)\n\n\t// Health check for cluster monitoring state\n\tHealthCheck(cluster string,\n\t\tnodes []string,\n\t\tmetrics []string) (map[string]metricstore.HealthCheckResult, error)\n}\n```\n\n### 2. **Implementation 1: Internal Metric Store**\n\n**Location:** `/Users/jan/prg/ClusterCockpit/cc-backend/pkg/metricstore/query.go` (lines 41-50)\n\n```go\ntype InternalMetricStore struct{}\n\nvar MetricStoreHandle *InternalMetricStore\n\n// Implements all MetricDataRepository methods\nfunc (ccms *InternalMetricStore) LoadData(...)

(schema.JobData, error)\nfunc (ccms *CCMetricStore) LoadStats(...) (map[string]map[string]schema.MetricStatistics, error)\n// ... and others\n```\n\n### 4. **Shared Types - `APIQuery` & `APIMetricData`**\n\nBoth packages define their **own copies** of these types (NOT shared):\n\n**In `pkg/metricstore/api.go` (lines 74-93):**\n```go\ntype APIQuery struct {\n\tType *string `json:\"type,omitempty\"`\n\tSubType *string `json:\"subtype,omitempty\"`\n\tMetric string `json:\"metric\"`\n\tHostname string `json:\"host\"`\n\tResolution int64 `json:\"resolution\"`\n\tTypeIds []string `json:\"type-ids,omitempty\"`\n\tSubTypeIds []string `json:\"subtype-ids,omitempty\"`\n\tScaleFactor schema.Float `json:\"scale-by,omitempty\"`\n\tAggregate bool `json:\"aggreg\"`\n}\n```\n\n**In `internal/metricstoreclient/cc-metric-store.go` (lines 93-104):**\n```go\ntype APIQuery struct {\n\tType *string `json:\"type,omitempty\"`\n\tSubType *string `json:\"subtype,omitempty\"`\n\tMetric string `json:\"metric\"`\n\tHostname string `json:\"host\"`\n\tResolution int `json:\"resolution\"`\n\tTypeIds []string `json:\"type-ids,omitempty\"`\n\tSubTypeIds []string `json:\"subtype-ids,omitempty\"`\n\tAggregate bool `json:\"aggreg\"`\n}\n```\n\n**Note:** These are separate definitions (not shared) - they're almost identical but used independently by each package.\n\n### 5. **Registration/Initialization**\n\n**Location:** `/Users/jan/prg/ClusterCockpit/cc-backend/cmd/cc-backend/main.go` (lines 320-346)\n\n```go\n// Initialize internal metric store\nmscfg := ccconf.GetPackageConfig(\"metric-store\")\nif mscfg != nil {\n\tmetricstore.Init(mscfg, metrics, &wg)\n\tms := metricstore.GetMemoryStore()\n\tjobRepo := repository.GetJobRepository()\n\tms.SetNodeProvider(jobRepo)\n\tmetricstore.MetricStoreHandle = &metricstore.InternalMetricStore{}\n\thaveMetricstore = true\n}\n\n// Initialize external metric store clients\nmscfg = ccconf.GetPackageConfig(\"metric-store-external\")\nif mscfg != nil {\n\terr := metricdispatch.Init(mscfg)\n\t// ...\n}\n```\n\n### 6. **Runtime Selection via `metricdispatch`**\n\n**Location:** `/Users/jan/prg/ClusterCockpit/cc-backend/internal/metricdispatch/metricdata.go` (lines 92-117)\n\nThe `GetMetricDataRepo()` function returns the appropriate implementation based on cluster/subcluster configuration:\n\n```go\nvar metricDataRepos map[string]MetricDataRepository = map[string]MetricDataRepository{}\n\nfunc GetMetricDataRepo(cluster string, subcluster string) (MetricDataRepository, error) {\n\t// Fallback chain:\n\t// 1. Try cluster + subcluster config\n\t// 2. Try cluster config only\n\t// 3. Try wildcard config\n\t// 4. Fall back to internal metric store (if available)\n\t// 5. Return error if none found\n\t\n\tif !ok && metricstore.MetricStoreHandle == nil {\n\t\treturn nil, fmt.Errorf(\"[METRICDISPATCH]> no metric data repository configured\")\n\t}\n\trepo = metricstore.MetricStoreHandle // Use internal as fallback\n}\n```\n\n### Key Architecture Points\n\n1. **Single Interface, Multiple Implementations:** The `MetricDataRepository` interface in `metricdispatch` is the bridge\n2. **Independent Type Definitions:** Each package defines its own `APIQuery` type for internal use\n3. **Dispatcher Pattern:** `internal/metricdispatch` acts as a registry and selector\n4. **Fallback to Internal:** If no external metric store is configured, falls back to `MetricStoreHandle`\n5. **No Shared Types Package:** There's no common `types.go` file - each package is self-contained and defines what it needs\n\n**Files involved:**\n- `/Users/jan/prg/ClusterCockpit/cc-backend/internal/metricdispatch/metricdata.go` — Interface definition and registry\n- `/Users/jan/prg/ClusterCockpit/cc-backend/pkg/metricstore/query.go` — Internal implementation\n- `/Users/jan/prg/ClusterCockpit/cc-backend/internal/metricstoreclient/cc-metric-store.go` — External client implementation\n- `/Users/jan/prg/ClusterCockpit/cc-backend/cmd/cc-backend/main.go` — Initialization"}],"totalDurationMs":38792,"totalTokens":46619,"totalToolUseCount":21,"usage":{"input_tokens":3,"cache_creation_input_tokens":1024,"cache_read_input_tokens":43486,"output_tokens":2106,"server_tool_use":{"web_search_requests":0,"web_fetch_requests":0},"service_tier":"standard","cache_creation":{"ephemeral_1h_input_tokens":1024,"ephemeral_5m_input_tokens":0},"inference_geo":"","iterations":[],"speed":"standard"}},"sourceToolAssistantUUID":"d26acb8a-07a8-46fe-8f14-b4fc2e9aff3d"} +{"parentUuid":"59b93734-24f6-4e65-b55a-b6ab85e03e83","isSidechain":false,"userType":"external","cwd":"/Users/jan/prg/ClusterCockpit/cc-backend","sessionId":"eec1fc87-d8f6-42f6-b296-d7a2f79af002","version":"2.1.66","gitBranch":"dev","slug":"curious-dancing-nebula","type":"progress","data":{"type":"hook_progress","hookEvent":"PostToolUse","hookName":"PostToolUse:Agent","command":"entire hooks claude-code post-task"},"parentToolUseID":"toolu_01An2GQTxJmdB2UZE56PWWKf","toolUseID":"toolu_01An2GQTxJmdB2UZE56PWWKf","timestamp":"2026-03-04T15:24:37.771Z","uuid":"a480ef03-2cd8-4395-b23b-46a02f213869"} +{"parentUuid":"87dce091-59a3-440c-aa2e-2f4904c0ff79","isSidechain":false,"userType":"external","cwd":"/Users/jan/prg/ClusterCockpit/cc-backend","sessionId":"eec1fc87-d8f6-42f6-b296-d7a2f79af002","version":"2.1.66","gitBranch":"dev","slug":"curious-dancing-nebula","type":"user","message":{"role":"user","content":[{"tool_use_id":"toolu_01An2GQTxJmdB2UZE56PWWKf","type":"tool_result","content":[{"type":"text","text":"Excellent!

Let me create a detailed summary report.\n\n## Comprehensive Exploration Report: `internal/metricstoreclient/` Package\n\n### Overview\n\nThe `internal/metricstoreclient/` package is a **client library for querying cc-metric-store**, an external high-performance time series database optimized for HPC metric data. It mirrors the functionality of `pkg/metricstore/query.go` but communicates with an external cc-metric-store service via HTTP instead of using an in-memory store.\n\n**Files in package:**\n- `/Users/jan/prg/ClusterCockpit/cc-backend/internal/metricstoreclient/cc-metric-store.go` (28 KB) — Main client operations\n- `/Users/jan/prg/ClusterCockpit/cc-backend/internal/metricstoreclient/cc-metric-store-queries.go` (16 KB) — Query building logic\n\n---\n\n### 1. Core Type: `CCMetricStore`\n\n**Location:** `cc-metric-store.go`, lines 71-79\n\n```go\ntype CCMetricStore struct {\n client http.Client // HTTP client with 10-second timeout\n jwt string // JWT Bearer token for authentication\n url string // Base URL of cc-metric-store instance\n queryEndpoint string // Full URL to query API endpoint\n topologyCache map[string]*schema.Topology // cluster -> topology cache\n}\n```\n\n**Purpose:** HTTP client for communicating with an external cc-metric-store service. Manages connection details, authentication (JWT), and caching of cluster topology information.\n\n**Constructor:**\n```go\nfunc NewCCMetricStore(url string, token string) *CCMetricStore\n```\n- Creates client with 10-second timeout\n- Initializes empty topology cache\n- URL should include protocol and port (e.g., \"http://localhost:8080\")\n- Token is JWT for Bearer authentication; empty string disables auth\n\n---\n\n### 2. API Request/Response Types\n\n#### `APIQueryRequest` (lines 83-91)\nRepresents a request to the cc-metric-store query API:\n```go\ntype APIQueryRequest struct {\n Cluster string // Target cluster name\n Queries []APIQuery // Explicit list of metric queries\n ForAllNodes []string // Metrics to query for all nodes (bulk query)\n From int64 // Start time (Unix timestamp)\n To int64 // End time (Unix timestamp)\n WithStats bool // Include min/avg/max statistics\n WithData bool // Include time series data points\n}\n```\n\n#### `APIQuery` (lines 95-104)\nSpecifies a single metric query with optional scope filtering:\n```go\ntype APIQuery struct {\n Type *string // Scope type (e.g., \"core\", \"socket\", \"hwthread\")\n SubType *string // Sub-scope type (reserved for future use)\n Metric string // Metric name\n Hostname string // Target hostname\n Resolution int // Data resolution in seconds (0 = native)\n TypeIds []string // IDs for the scope type (e.g., [\"0\", \"1\", \"2\"] for core IDs)\n SubTypeIds []string // IDs for sub-scope (reserved)\n Aggregate bool // Aggregate across TypeIds\n}\n```\n\n#### `APIQueryResponse` (lines 108-111)\nContains results from a cc-metric-store query:\n```go\ntype APIQueryResponse struct {\n Queries []APIQuery // Echoed queries (for bulk requests)\n Results [][]APIMetricData // Result data, indexed by query\n}\n```\n\n#### `APIMetricData` (lines 115-124)\nTime series data and statistics for a single metric series:\n```go\ntype APIMetricData struct {\n Error *string // Error message if query failed\n Data []schema.Float // Time series data points\n From int64 // Actual start time of data\n To int64 // Actual end time of data\n Resolution int // Actual resolution of data in seconds\n Avg schema.Float // Average value across time range\n Min schema.Float // Minimum value in time range\n Max schema.Float // Maximum value in time range\n}\n```\n\n---\n\n### 3. Core Methods on `CCMetricStore`\n\n#### `doRequest()` (lines 144-188)\n**Purpose:** Executes HTTP POST request to cc-metric-store query API\n\n**Key behavior:**\n- Encodes request body as JSON\n- Adds JWT Bearer token if configured\n- Adds API versioning (v2 for data with resampling, v1 without)\n- Uses GET method with JSON body (unusual but matches cc-metric-store API)\n- Returns parsed `APIQueryResponse`\n- Properly closes response body to prevent resource leaks\n\n#### `getTopology()` (lines 191-204)\n**Purpose:** Returns topology for given cluster and subcluster, caching results\n\n```go\nfunc (ccms *CCMetricStore) getTopology(cluster, subCluster string) (*schema.Topology, error)\n```\n\n**Implementation:**\n- Uses cache key `\"cluster:subcluster\"`\n- Returns cached topology if available\n- Otherwise loads via `archive.GetSubCluster()` and caches it\n- Returns pointer to `schema.Topology` from subcluster\n\n#### `getTopologyByNode()` (lines 207-214)\n**Purpose:** Returns topology for given cluster and node, caching it\n\n```go\nfunc (ccms *CCMetricStore) getTopologyByNode(cluster, node string) (*schema.Topology, error)\n```\n\n**Implementation:**\n- Uses `archive.GetSubClusterByNode()` to find subcluster for node\n- Delegates to `getTopology()` for cache lookup and loading\n\n---\n\n### 4. Main Data Loading Methods\n\n#### `LoadData()` (lines 228-362)\n**Purpose:** Retrieves time series data and statistics for specified job and metrics\n\n**Signature:**\n```go\nfunc (ccms *CCMetricStore) LoadData(\n job *schema.Job,\n metrics []string,\n scopes []schema.MetricScope,\n ctx context.Context,\n resolution int,\n) (schema.JobData, error)\n```\n\n**Returns:** `schema.JobData` organized as: `metric → scope → series list`\n\n**Key steps:**\n1. Calls `buildQueries()` to construct API queries with scope transformations\n2. Creates `APIQueryRequest` with job time range and resources\n3. Calls `doRequest()` to fetch from cc-metric-store\n4. Processes results with safety checks for index bounds\n5. For each result, extracts metric config and builds `schema.Series` objects\n6. Supports partial errors: returns available data even if some queries fail\n7. Sanitizes NaN statistics for JSON compatibility\n\n#### `LoadStats()` (lines 368-427)\n**Purpose:** Retrieves min/avg/max statistics for job metrics at node scope (faster, no time series data)\n\n**Signature:**\n```go\nfunc (ccms *CCMetricStore) LoadStats(\n job *schema.Job,\n metrics []string,\n ctx context.Context,\n) (map[string]map[string]schema.MetricStatistics, error)\n```\n\n**Returns:** Statistics organized as: `metric → hostname → statistics`\n\n**Key differences from LoadData:**\n- Only queries node scope\n- Sets `WithData: false` (no time series)\n- Sets `WithStats: true` (only statistics)\n- Simpler result processing\n\n#### `LoadScopedStats()` (lines 434-524)\n**Purpose:** Retrieves statistics for job metrics across multiple scopes (used for Job-View Statistics Table)\n\n**Signature:**\n```go\nfunc (ccms *CCMetricStore) LoadScopedStats(\n job *schema.Job,\n metrics []string,\n scopes []schema.MetricScope,\n ctx context.Context,\n) (schema.ScopedJobStats, error)\n```\n\n**Returns:** Statistics organized as: `metric → scope → list of scoped statistics`\n\n**Key features:**\n- Similar structure to `LoadData()` but returns `schema.ScopedStats` instead of full series\n- Each scoped stat includes hostname, hardware ID (if applicable), and min/avg/max\n\n#### `LoadNodeData()` (lines 531-619)\n**Purpose:** Retrieves current metric data for specified nodes in a cluster (Systems-View Node-Overview)\n\n**Signature:**\n```go\nfunc (ccms *CCMetricStore) LoadNodeData(\n cluster string,\n metrics, nodes []string,\n scopes []schema.MetricScope,\n from, to time.Time,\n ctx context.Context,\n) (map[string]map[string][]*schema.JobMetric, error)\n```\n\n**Returns:** Data organized as: `hostname → metric → []*JobMetric` (list supports multiple scopes)\n\n**Key features:**\n- If `nodes == nil`: performs bulk query for all metrics on all nodes\n- Otherwise: queries each specified node for each metric\n- Simpler query construction (doesn't call `buildQueries()`)\n- No scope transformations applied\n\n#### `LoadNodeListData()` (lines 631-780)\n**Purpose:** Retrieves paginated node metrics for Systems-View Node-List with filtering\n\n**Signature:**\n```go\nfunc (ccms *CCMetricStore) LoadNodeListData(\n cluster, subCluster string,\n nodes []string,\n metrics []string,\n scopes []schema.MetricScope,\n resolution int,\n from, to time.Time,\n ctx context.Context,\n) (map[string]schema.JobData, error)\n```\n\n**Returns:** Data organized as: `hostname → JobData (metric → scope → series)`\n\n**Key steps:**\n1. Calls `buildNodeQueries()` for query construction with scope transformations\n2. Uses `getTopology()` or `getTopologyByNode()` depending on subcluster parameter\n3. Similar result processing to `LoadData()` with safety checks\n\n#### `HealthCheck()` (lines 785-828)\n**Purpose:** Queries external cc-metric-store's health check endpoint\n\n**Key features:**\n- Sends `metricstore.HealthCheckReq` with cluster, nodes, metrics\n- Uses `/api/healthcheck` endpoint\n- Returns per-node health check results\n\n---\n\n### 5. Query Building (cc-metric-store-queries.go)\n\n#### Scope String Constants (lines 49-55)\nPre-converted strings to avoid repeated allocations:\n```go\nhwthreadString = \"hwthread\"\ncoreString = \"core\"\nmemoryDomainString = \"memory_domain\"\nsocketString = \"socket\"\nacceleratorString = \"accelerator\"\n```\n\n#### `buildQueries()` (lines 67-149)\n**Purpose:** Constructs API queries for job-specific metric data\n\n**Signature:**\n```go\nfunc (ccms *CCMetricStore) buildQueries(\n job *schema.Job,\n metrics []string,\n scopes []schema.MetricScope,\n resolution int,\n) ([]APIQuery, []schema.MetricScope, error)\n```\n\n**Returns:** Both queries and their corresponding assigned scopes (may differ from requested)\n\n**Key logic:**\n1. Validates metric configurations via `archive.GetMetricConfig()`\n2. Skips metrics removed for subcluster\n3. Deduplicates requested scopes to avoid redundant queries\n4. For each host in job resources:\n - Uses job-allocated HWThreads (or full node if not specified)\n - Calls `buildScopeQueries()` for scope transformation\n - Accumulates queries and assigned scopes\n\n**Optimization:** Tracks handled scopes to skip redundant queries\n\n#### `buildNodeQueries()` (lines 161-252)\n**Purpose:** Constructs API queries for node-specific metric data (Systems View)\n\n**Signature:**\n```go\nfunc (ccms *CCMetricStore) buildNodeQueries(\n cluster string,\n subCluster string,\n nodes []string,\n metrics []string,\n scopes []schema.MetricScope,\n resolution int,\n) ([]APIQuery, []schema.MetricScope, error)\n```\n\n**Key differences from `buildQueries()`:**\n- Always uses full node topology (not job-specific subsets)\n- Always uses all accelerators on each node\n- Handles optional subCluster parameter:\n - If empty: calls `getTopologyByNode()` per node\n - If provided: calls `getTopology()` once and reuses\n\n#### `buildScopeQueries()` (lines 257-517)\n**Purpose:** Generates API queries for a given scope transformation\n\n**Signature:**\n```go\nfunc buildScopeQueries(\n nativeScope, requestedScope schema.MetricScope,\n metric, hostname string,\n topology *schema.Topology,\n hwthreads []int,\n accelerators []string,\n resolution int,\n) ([]APIQuery, []schema.MetricScope)\n```\n\n**Returns:** Empty slices for expected exceptions; nil for unexpected unhandled cases\n\n**Scope Transformations Implemented (25+ cases):**\n\n| Native → Requested | Behavior | Result Scope |\n|---|---|---|\n| Accelerator → Accelerator | Return as-is | Accelerator |\n| Accelerator → Node | Aggregate all accelerators | Node |\n| HWThread → HWThread | Return as-is | HWThread |\n| HWThread → Core | Aggregate per core | Core (one query per core) |\n| HWThread → Socket | Aggregate per socket | Socket (one query per socket) |\n| HWThread → Node | Aggregate all threads | Node |\n| Core → Core | Return as-is | Core |\n| Core → Socket | Aggregate per socket | Socket (one query per socket) |\n| Core → Node | Aggregate all cores | Node |\n| MemoryDomain → MemoryDomain | Return as-is | MemoryDomain |\n| MemoryDomain → Node | Aggregate all domains | Node |\n| MemoryDomain → Socket | Aggregate domains per socket | Socket (one query per socket) |\n| Socket → Socket | Return as-is | Socket |\n| Socket → Node | Aggregate all sockets | Node |\n| Node → Node | Return as-is | Node |\n\n**Key features:**\n- Uses `Aggregate: true` for aggregations, `false` for direct queries\n- Sets `Type` and `TypeIds` for scope-specific queries\n- Returns nil slices for unhandled cases (triggers error in `buildQueries()`)\n- Uses helper functions like `GetCoresFromHWThreads()`, `GetSocketsFromCores()`, etc. from topology\n\n#### `intToStringSlice()` (lines 521-527)\nHelper function to convert integer hardware IDs to string format required by API:\n```go\nfunc intToStringSlice(is []int) []string\n```\n\n---\n\n### 6. Helper Functions\n\n#### `sanitizeStats()` (lines 832-838)\nReplaces NaN values in statistics with 0 to enable JSON marshaling:\n```go\nfunc sanitizeStats(avg, min, max *schema.Float)\n```\n\n#### `hasNaNStats()` (lines 841-843)\nReturns true if any of the statistics contain NaN values:\n```go\nfunc hasNaNStats(avg, min, max schema.Float) bool\n```\n\n---\n\n### 7. Relationship to `pkg/metricstore/query.go`\n\nBoth packages implement **parallel interfaces** with nearly identical method signatures:\n\n| Method | Location | Purpose |\n|---|---|---|\n| `LoadData()` | Both | Load job metric data with scope transformations |\n| `LoadStats()` | Both | Load statistics at node scope |\n| `LoadScopedStats()` | Both | Load statistics across multiple scopes |\n| `HealthCheck()` | Both | Health check for metric store |\n\n**Key differences:**\n\n| Aspect | `pkg/metricstore/` | `internal/metricstoreclient/` |\n|---|---|---|\n| **Storage** | In-memory store | External cc-metric-store via HTTP |\n| **Data fetching** | `FetchData()` (internal) | `doRequest()` (HTTP to cc-metric-store) |\n| **Query builder** | `buildQueries()` in query.go | `buildQueries()` + `buildScopeQueries()` in cc-metric-store-queries.go |\n| **Authentication** | None (in-process) | JWT Bearer token |\n| **Caching** | No caching | Topology caching |\n| **API versioning** | Not applicable | Uses cc-metric-store v2 API |\n| **Timeout** | Not applicable | 10-second HTTP timeout |\n| **Resolution type** | `int64` | `int` |\n\n**Code Similarity:**\n- Both use same scope transformation logic\n- Both construct queries with metric configs from `archive.GetMetricConfig()`\n- Both handle partial errors (return data for successful queries)\n- Both sanitize NaN statistics\n- Nearly identical result processing loops with identical safety checks\n\n**When to use each:**\n- **`pkg/metricstore/`**: When cc-metric-store is co-located or unavailable\n- **`internal/metricstoreclient/`**: When cc-metric-store is available externally (production preferred for scalability)\n\n---\n\n### 8. API Endpoint Details\n\n**Query Endpoint:**\n- Base: `http://cc-metric-store-host:port`\n- Query: `{base}/api/query?version=v2`\n- Health: `{base}/api/healthcheck`\n\n**Message Format:**\nUses InfluxDB-like line protocol with JSON payloads in `APIQuery` structures. For job events/node updates via NATS (per CLAUDE.md), uses InfluxDB line protocol directly.\n\n---\n\n### 9. Error Handling\n\n- **Partial errors**: Methods return both data and error; error lists failed queries\n- **Index out of range**: Prevented with bounds checking; logged as warnings\n- **Invalid scopes**: Return nil slices from `buildScopeQueries()` triggering error\n- **Metric config missing**: Logged warning, metric skipped\n- **HTTP errors**: Returned from `doRequest()`\n- **Context cancellation**: Supported via context parameter in all load methods\n\n---\n\n### Summary\n\nThe `internal/metricstoreclient/` package is a **complete HTTP client for external cc-metric-store** that mirrors the functionality of the internal metric store while communicating via HTTP API. It handles complex scope transformations, topology caching, and partial error reporting. The query building logic handles 25+ scope transformation cases, enabling flexible metric data requests across different hardware granularities while maintaining compatibility with the in-memory metric store interface."},{"type":"text","text":"agentId: ac0e18c809f60baa6 (for resuming to continue this agent's work if needed)\ntotal_tokens: 42376\ntool_uses: 6\nduration_ms: 47035"}]}]},"uuid":"0dac97f6-1f19-4ba7-88d6-eb2125a33bbd","timestamp":"2026-03-04T15:24:37.770Z","toolUseResult":{"status":"completed","prompt":"Explore the internal/metricstoreclient/ package thoroughly.

Processes results with safety checks for index bounds\n5. For each result, extracts metric config and builds `schema.Series` objects\n6. Supports partial errors: returns available data even if some queries fail\n7. Sanitizes NaN statistics for JSON compatibility\n\n#### `LoadStats()` (lines 368-427)\n**Purpose:** Retrieves min/avg/max statistics for job metrics at node scope (faster, no time series data)\n\n**Signature:**\n```go\nfunc (ccms *CCMetricStore) LoadStats(\n job *schema.Job,\n metrics []string,\n ctx context.Context,\n) (map[string]map[string]schema.MetricStatistics, error)\n```\n\n**Returns:** Statistics organized as: `metric → hostname → statistics`\n\n**Key differences from LoadData:**\n- Only queries node scope\n- Sets `WithData: false` (no time series)\n- Sets `WithStats: true` (only statistics)\n- Simpler result processing\n\n#### `LoadScopedStats()` (lines 434-524)\n**Purpose:** Retrieves statistics for job metrics across multiple scopes (used for Job-View Statistics Table)\n\n**Signature:**\n```go\nfunc (ccms *CCMetricStore) LoadScopedStats(\n job *schema.Job,\n metrics []string,\n scopes []schema.MetricScope,\n ctx context.Context,\n) (schema.ScopedJobStats, error)\n```\n\n**Returns:** Statistics organized as: `metric → scope → list of scoped statistics`\n\n**Key features:**\n- Similar structure to `LoadData()` but returns `schema.ScopedStats` instead of full series\n- Each scoped stat includes hostname, hardware ID (if applicable), and min/avg/max\n\n#### `LoadNodeData()` (lines 531-619)\n**Purpose:** Retrieves current metric data for specified nodes in a cluster (Systems-View Node-Overview)\n\n**Signature:**\n```go\nfunc (ccms *CCMetricStore) LoadNodeData(\n cluster string,\n metrics, nodes []string,\n scopes []schema.MetricScope,\n from, to time.Time,\n ctx context.Context,\n) (map[string]map[string][]*schema.JobMetric, error)\n```\n\n**Returns:** Data organized as: `hostname → metric → []*JobMetric` (list supports multiple scopes)\n\n**Key features:**\n- If `nodes == nil`: performs bulk query for all metrics on all nodes\n- Otherwise: queries each specified node for each metric\n- Simpler query construction (doesn't call `buildQueries()`)\n- No scope transformations applied\n\n#### `LoadNodeListData()` (lines 631-780)\n**Purpose:** Retrieves paginated node metrics for Systems-View Node-List with filtering\n\n**Signature:**\n```go\nfunc (ccms *CCMetricStore) LoadNodeListData(\n cluster, subCluster string,\n nodes []string,\n metrics []string,\n scopes []schema.MetricScope,\n resolution int,\n from, to time.Time,\n ctx context.Context,\n) (map[string]schema.JobData, error)\n```\n\n**Returns:** Data organized as: `hostname → JobData (metric → scope → series)`\n\n**Key steps:**\n1. Calls `buildNodeQueries()` for query construction with scope transformations\n2. Uses `getTopology()` or `getTopologyByNode()` depending on subcluster parameter\n3. Similar result processing to `LoadData()` with safety checks\n\n#### `HealthCheck()` (lines 785-828)\n**Purpose:** Queries external cc-metric-store's health check endpoint\n\n**Key features:**\n- Sends `metricstore.HealthCheckReq` with cluster, nodes, metrics\n- Uses `/api/healthcheck` endpoint\n- Returns per-node health check results\n\n---\n\n### 5. Query Building (cc-metric-store-queries.go)\n\n#### Scope String Constants (lines 49-55)\nPre-converted strings to avoid repeated allocations:\n```go\nhwthreadString = \"hwthread\"\ncoreString = \"core\"\nmemoryDomainString = \"memory_domain\"\nsocketString = \"socket\"\nacceleratorString = \"accelerator\"\n```\n\n#### `buildQueries()` (lines 67-149)\n**Purpose:** Constructs API queries for job-specific metric data\n\n**Signature:**\n```go\nfunc (ccms *CCMetricStore) buildQueries(\n job *schema.Job,\n metrics []string,\n scopes []schema.MetricScope,\n resolution int,\n) ([]APIQuery, []schema.MetricScope, error)\n```\n\n**Returns:** Both queries and their corresponding assigned scopes (may differ from requested)\n\n**Key logic:**\n1.

Helper Functions\n\n#### `sanitizeStats()` (lines 832-838)\nReplaces NaN values in statistics with 0 to enable JSON marshaling:\n```go\nfunc sanitizeStats(avg, min, max *schema.Float)\n```\n\n#### `hasNaNStats()` (lines 841-843)\nReturns true if any of the statistics contain NaN values:\n```go\nfunc hasNaNStats(avg, min, max schema.Float) bool\n```\n\n---\n\n### 7. Relationship to `pkg/metricstore/query.go`\n\nBoth packages implement **parallel interfaces** with nearly identical method signatures:\n\n| Method | Location | Purpose |\n|---|---|---|\n| `LoadData()` | Both | Load job metric data with scope transformations |\n| `LoadStats()` | Both | Load statistics at node scope |\n| `LoadScopedStats()` | Both | Load statistics across multiple scopes |\n| `HealthCheck()` | Both | Health check for metric store |\n\n**Key differences:**\n\n| Aspect | `pkg/metricstore/` | `internal/metricstoreclient/` |\n|---|---|---|\n| **Storage** | In-memory store | External cc-metric-store via HTTP |\n| **Data fetching** | `FetchData()` (internal) | `doRequest()` (HTTP to cc-metric-store) |\n| **Query builder** | `buildQueries()` in query.go | `buildQueries()` + `buildScopeQueries()` in cc-metric-store-queries.go |\n| **Authentication** | None (in-process) | JWT Bearer token |\n| **Caching** | No caching | Topology caching |\n| **API versioning** | Not applicable | Uses cc-metric-store v2 API |\n| **Timeout** | Not applicable | 10-second HTTP timeout |\n| **Resolution type** | `int64` | `int` |\n\n**Code Similarity:**\n- Both use same scope transformation logic\n- Both construct queries with metric configs from `archive.GetMetricConfig()`\n- Both handle partial errors (return data for successful queries)\n- Both sanitize NaN statistics\n- Nearly identical result processing loops with identical safety checks\n\n**When to use each:**\n- **`pkg/metricstore/`**: When cc-metric-store is co-located or unavailable\n- **`internal/metricstoreclient/`**: When cc-metric-store is available externally (production preferred for scalability)\n\n---\n\n### 8. API Endpoint Details\n\n**Query Endpoint:**\n- Base: `http://cc-metric-store-host:port`\n- Query: `{base}/api/query?version=v2`\n- Health: `{base}/api/healthcheck`\n\n**Message Format:**\nUses InfluxDB-like line protocol with JSON payloads in `APIQuery` structures. For job events/node updates via NATS (per CLAUDE.md), uses InfluxDB line protocol directly.\n\n---\n\n### 9. Error Handling\n\n- **Partial errors**: Methods return both data and error; error lists failed queries\n- **Index out of range**: Prevented with bounds checking; logged as warnings\n- **Invalid scopes**: Return nil slices from `buildScopeQueries()` triggering error\n- **Metric config missing**: Logged warning, metric skipped\n- **HTTP errors**: Returned from `doRequest()`\n- **Context cancellation**: Supported via context parameter in all load methods\n\n---\n\n### Summary\n\nThe `internal/metricstoreclient/` package is a **complete HTTP client for external cc-metric-store** that mirrors the functionality of the internal metric store while communicating via HTTP API. It handles complex scope transformations, topology caching, and partial error reporting. The query building logic handles 25+ scope transformation cases, enabling flexible metric data requests across different hardware granularities while maintaining compatibility with the in-memory metric store interface."}],"totalDurationMs":47035,"totalTokens":42376,"totalToolUseCount":6,"usage":{"input_tokens":4,"cache_creation_input_tokens":3077,"cache_read_input_tokens":34757,"output_tokens":4538,"server_tool_use":{"web_search_requests":0,"web_fetch_requests":0},"service_tier":"standard","cache_creation":{"ephemeral_1h_input_tokens":3077,"ephemeral_5m_input_tokens":0},"inference_geo":"","iterations":[],"speed":"standard"}},"sourceToolAssistantUUID":"87dce091-59a3-440c-aa2e-2f4904c0ff79"} +{"parentUuid":"0dac97f6-1f19-4ba7-88d6-eb2125a33bbd","isSidechain":false,"userType":"external","cwd":"/Users/jan/prg/ClusterCockpit/cc-backend","sessionId":"eec1fc87-d8f6-42f6-b296-d7a2f79af002","version":"2.1.66","gitBranch":"dev","slug":"curious-dancing-nebula","type":"progress","data":{"type":"hook_progress","hookEvent":"PostToolUse","hookName":"PostToolUse:Agent","command":"entire hooks claude-code post-task"},"parentToolUseID":"toolu_01JPUhKVS2cG5n57jLbfbvoS","toolUseID":"toolu_01JPUhKVS2cG5n57jLbfbvoS","timestamp":"2026-03-04T15:24:44.624Z","uuid":"93c1535f-6b4a-4b9b-adf7-4422ee8623e8"} +{"parentUuid":"11e11771-ff9d-464d-948f-664179635a98","isSidechain":false,"userType":"external","cwd":"/Users/jan/prg/ClusterCockpit/cc-backend","sessionId":"eec1fc87-d8f6-42f6-b296-d7a2f79af002","version":"2.1.66","gitBranch":"dev","slug":"curious-dancing-nebula","type":"user","message":{"role":"user","content":[{"tool_use_id":"toolu_01JPUhKVS2cG5n57jLbfbvoS","type":"tool_result","content":[{"type":"text","text":"Perfect!

HOW FetchData WORKS\n\n**Function Signature**: `func FetchData(req APIQueryRequest) (*APIQueryResponse, error)`\n\n**High-Level Flow**:\n\n1. **Validation**\n - Checks `req.From <= req.To`\n - Ensures cluster is specified if `ForAllNodes` is used\n - Verifies MemoryStore is initialized\n\n2. **Query Expansion**\n - If `req.ForAllNodes` is set: auto-generates queries for all nodes in the cluster\n - Calls `ms.ListChildren([]string{cluster})` to get node list\n - Creates one query per (node, metric) combination\n\n3. **Selector Construction** (per query)\n - Base selector: `[cluster, hostname]`\n - If `Aggregate=true` or no Type specified:\n - Creates single aggregated selector\n - If Type is specified and has multiple TypeIds:\n - Uses `SelectorElement{Group: ids}` for multi-selection\n - Similar for SubType\n - If `Aggregate=false`:\n - Creates individual selector for each Type/SubType ID combination\n - Enables non-aggregated per-component results\n\n4. **Data Fetching**\n - For each selector: calls `ms.Read(selector, metric, from, to, resolution)`\n - Returns: `(data, from, to, resolution, error)`\n\n5. **Result Processing** (per query result)\n - **Skips** `ErrNoHostOrMetric` errors (logs warning, continues)\n - **Includes** other errors in `APIMetricData.Error` field\n - If `req.WithStats`: calls `data.AddStats()` to compute avg/min/max\n - If `query.ScaleFactor != 0`: calls `data.ScaleBy()` for unit conversion\n - If `req.WithPadding`: calls `data.PadDataWithNull()` to align timestamps\n - If `!req.WithData`: clears the data array (keeps stats)\n\n6. **Response Assembly**\n - Returns 2D array: `Results[query_idx][selector_idx]`\n - Each inner element is `APIMetricData` with data/stats\n\n**Example Scenario**:\n```\nRequest: Fetch cpu_load for cluster \"emmy\", node \"node001\", all cores (0-3)\n Type=\"core\", TypeIds=[\"0\",\"1\",\"2\",\"3\"], Aggregate=false\n\nResult: 4 separate APIMetricData entries, one per core\n (each with separate data points)\n```\n\n---\n\n## 3. InternalMetricStore & Its Relationship\n\n### Purpose\n`InternalMetricStore` is a **public facade** that abstracts the `MemoryStore` singleton, preventing direct exposure of internal details.\n\n### Key Methods\n\n**`LoadData()`** (query.go)\n```go\nfunc (ccms *InternalMetricStore) LoadData(\n job *schema.Job,\n metrics []string,\n scopes []schema.MetricScope,\n ctx context.Context,\n resolution int,\n) (schema.JobData, error)\n```\n\n**Responsibilities**:\n1. Calls `buildQueries()` to construct API queries with scope transformation\n2. Determines target scope for each query (e.g., HWThread native → Socket requested)\n3. Calls `FetchData()` to retrieve metric data\n4. Reorganizes results by metric and scope into `schema.JobData` structure\n5. Returns: `map[metricName]map[scope]*JobMetric`\n\n**Scope Transformation Logic** (in `buildQueries()`):\n- Native scope >= requested scope: **Aggregate** data (Aggregate=true)\n- Native scope < requested scope: **Error** (cannot refine granularity)\n- Handles special cases:\n - Accelerator metrics (no aggregation)\n - Memory domain metrics\n - Multi-node jobs (per-node queries)\n\n**`HealthCheck()`** (query.go)\n```go\nfunc (ccms *InternalMetricStore) HealthCheck(\n cluster string,\n nodes []string,\n metrics []string,\n) (map[string]HealthCheckResult, error)\n```\n- Delegates to `ms.HealthCheck()`\n- Returns monitoring state per node (Full/Partial/Failed)\n\n### Relationship to MemoryStore\n\n| Aspect | InternalMetricStore | MemoryStore |\n|--------|---------------------|------------|\n| **Role** | Public API facade | Internal storage/retrieval |\n| **Instance** | Singleton (var MetricStoreHandle) | Singleton (msInstance) |\n| **Access** | Used by external packages | Only via InternalMetricStore |\n| **Methods** | High-level: LoadData, HealthCheck | Low-level: Write, Read, Free |\n| **Scope** | Job-centric, scope transformation | Metric-centric, raw storage |\n\n---\n\n## 4. KEY DATA STRUCTURES & RELATIONSHIPS\n\n### Hierarchical Tree Organization\n\n```\nMemoryStore\n└── root (Level)\n └── children[\"emmy\"] (cluster Level)\n └── metrics [buffer, buffer, ...] (node-level aggregates)\n └── children[\"node001\"] (host Level)\n └── metrics [buffer, buffer, ...]\n └── children[\"socket0\"] (Level)\n └── metrics [buffer, buffer, ...]\n └── children[\"core0\"] (Level)\n └── metrics [buffer, buffer, ...] (actual data)\n └── children[\"core1\"]\n └── metrics [buffer, buffer, ...]\n```\n\n### Buffer Chain (Linked List)\n\nTime ordering: oldest ← prev -- prev -- newest (head)\n\n```\n[start=1000] ← [start=1512] ← [start=2024] (head)\n data[512] data[512] data[42]\n```\n\n### Metrics Indexing\n\n- Each `Level.metrics` is a slice of `*buffer`\n- Index = `MetricConfig.offset` (assigned during `InitMetrics()`)\n- Example:\n ```\n Metrics map: {\"cpu_load\": {offset: 0}, \"mem_used\": {offset: 1}}\n Level.metrics: [*buffer for cpu_load, *buffer for mem_used]\n ```\n\n---\n\n## 5.

TYPE DEFINITIONS\n\n### Core Types\n\n**APIMetricData** (api.go)\n```go\ntype APIMetricData struct {\n Error *string // Error message if retrieval failed\n Data schema.FloatArray // Time-series data points\n From int64 // Actual start timestamp\n To int64 // Actual end timestamp\n Resolution int64 // Resolution in seconds\n Avg schema.Float // Average of data points\n Min schema.Float // Minimum value\n Max schema.Float // Maximum value\n}\n```\n\n**APIQueryRequest** (api.go)\n```go\ntype APIQueryRequest struct {\n Cluster string // Cluster name\n Queries []APIQuery // Individual metric queries\n ForAllNodes []string // Auto-generate queries for all nodes in cluster (metric names)\n From int64 // Start timestamp\n To int64 // End timestamp\n WithStats bool // Compute avg/min/max\n WithData bool // Include data array\n WithPadding bool // Pad with NaN at start\n}\n```\n\n**APIQuery** (api.go)\n```go\ntype APIQuery struct {\n Type *string // Scope level (e.g., \"hwthread\", \"core\", \"socket\")\n SubType *string // Sub-level scope (e.g., \"core\" under \"socket\")\n Metric string // Metric name\n Hostname string // Node hostname\n Resolution int64 // Requested resolution\n TypeIds []string // IDs for Type level (e.g., [\"0\", \"1\", \"2\"] for cores)\n SubTypeIds []string // IDs for SubType level\n ScaleFactor schema.Float // Multiplier for unit conversion\n Aggregate bool // Sum/avg across TypeIds/SubTypeIds\n}\n```\n\n**APIQueryResponse** (api.go)\n```go\ntype APIQueryResponse struct {\n Queries []APIQuery // Echo of input queries\n Results [][]APIMetricData // Results: [query_idx][selector_idx]\n}\n```\n\n### Storage Types\n\n**MemoryStore** (metricstore.go)\n```go\ntype MemoryStore struct {\n Metrics map[string]MetricConfig // Metric config map (name → MetricConfig)\n root Level // Root of hierarchical tree\n nodeProvider NodeProvider // For job-aware retention\n}\n```\n\n**Level** (level.go) - Hierarchical tree node\n```go\ntype Level struct {\n children map[string]*Level // Child levels (e.g., \"node001\" → Level)\n metrics []*buffer // Metric buffers (indexed by MetricConfig.offset)\n lock sync.RWMutex // Protects concurrent access\n}\n```\n\n**buffer** (buffer.go) - Time-series data storage\n```go\ntype buffer struct {\n prev *buffer // Older buffer in chain\n next *buffer // Newer buffer in chain\n data []schema.Float // Data points\n frequency int64 // Measurement interval (seconds)\n start int64 // Start timestamp (adjusted by -frequency/2)\n archived bool // Persisted to archive\n closed bool // No longer accepting writes\n lastUsed int64 // Last used timestamp (for pool cleanup)\n}\n```\n\n### Configuration Types\n\n**MetricConfig** (config.go)\n```go\ntype MetricConfig struct {\n Frequency int64 // Measurement interval in seconds\n Aggregation AggregationStrategy // How to combine values (sum/avg/none)\n offset int // Internal index into Level.metrics\n}\n```\n\n**AggregationStrategy** (config.go)\n```go\nconst (\n NoAggregation AggregationStrategy = iota // Incompatible scopes\n SumAggregation // Add values (power, energy)\n AvgAggregation // Average values (temperature)\n)\n```\n\n**MetricStoreConfig** (config.go)\n```go\ntype MetricStoreConfig struct {\n NumWorkers int // Workers for checkpoint/archive\n RetentionInMemory string // Duration (e.g., \"48h\")\n MemoryCap int // Memory cap in bytes\n Checkpoints Checkpoints // Checkpoint settings\n Debug *Debug // Debug options\n Cleanup *Cleanup // Archive settings\n Subscriptions *Subscriptions // NATS topics\n}\n```\n\n### Query Building Types\n\n**InternalMetricStore** (query.go)\n```go\ntype InternalMetricStore struct{}\nvar MetricStoreHandle *InternalMetricStore\n```\n- Provides public API for job data loading\n- Methods: `LoadData()`, `HealthCheck()`\n- Delegates to underlying `MemoryStore`\n\n### Health Check Types\n\n**HealthCheckResult** (healthcheck.go)\n```go\ntype HealthCheckResult struct {\n State schema.MonitoringState // Full/Partial/Failed\n HealthMetrics string // JSON: {\"missing\":[...],\"degraded\":[...]}\n}\n```\n\n---\n\n## 2. HOW FetchData WORKS\n\n**Function Signature**: `func FetchData(req APIQueryRequest) (*APIQueryResponse, error)`\n\n**High-Level Flow**:\n\n1. **Validation**\n - Checks `req.From <= req.To`\n - Ensures cluster is specified if `ForAllNodes` is used\n - Verifies MemoryStore is initialized\n\n2. **Query Expansion**\n - If `req.ForAllNodes` is set: auto-generates queries for all nodes in the cluster\n - Calls `ms.ListChildren([]string{cluster})` to get node list\n - Creates one query per (node, metric) combination\n\n3. **Selector Construction** (per query)\n - Base selector: `[cluster, hostname]`\n - If `Aggregate=true` or no Type specified:\n - Creates single aggregated selector\n - If Type is specified and has multiple TypeIds:\n - Uses `SelectorElement{Group: ids}` for multi-selection\n - Similar for SubType\n - If `Aggregate=false`:\n - Creates individual selector for each Type/SubType ID combination\n - Enables non-aggregated per-component results\n\n4. **Data Fetching**\n - For each selector: calls `ms.Read(selector, metric, from, to, resolution)`\n - Returns: `(data, from, to, resolution, error)`\n\n5. **Result Processing** (per query result)\n - **Skips** `ErrNoHostOrMetric` errors (logs warning, continues)\n - **Includes** other errors in `APIMetricData.Error` field\n - If `req.WithStats`: calls `data.AddStats()` to compute avg/min/max\n - If `query.ScaleFactor != 0`: calls `data.ScaleBy()` for unit conversion\n - If `req.WithPadding`: calls `data.PadDataWithNull()` to align timestamps\n - If `!req.WithData`: clears the data array (keeps stats)\n\n6. **Response Assembly**\n - Returns 2D array: `Results[query_idx][selector_idx]`\n - Each inner element is `APIMetricData` with data/stats\n\n**Example Scenario**:\n```\nRequest: Fetch cpu_load for cluster \"emmy\", node \"node001\", all cores (0-3)\n Type=\"core\", TypeIds=[\"0\",\"1\",\"2\",\"3\"], Aggregate=false\n\nResult: 4 separate APIMetricData entries, one per core\n (each with separate data points)\n```\n\n---\n\n## 3. InternalMetricStore & Its Relationship\n\n### Purpose\n`InternalMetricStore` is a **public facade** that abstracts the `MemoryStore` singleton, preventing direct exposure of internal details.\n\n### Key Methods\n\n**`LoadData()`** (query.go)\n```go\nfunc (ccms *InternalMetricStore) LoadData(\n job *schema.Job,\n metrics []string,\n scopes []schema.MetricScope,\n ctx context.Context,\n resolution int,\n) (schema.JobData, error)\n```\n\n**Responsibilities**:\n1. Calls `buildQueries()` to construct API queries with scope transformation\n2. Determines target scope for each query (e.g., HWThread native → Socket requested)\n3. Calls `FetchData()` to retrieve metric data\n4. Reorganizes results by metric and scope into `schema.JobData` structure\n5. Returns: `map[metricName]map[scope]*JobMetric`\n\n**Scope Transformation Logic** (in `buildQueries()`):\n- Native scope >= requested scope: **Aggregate** data (Aggregate=true)\n- Native scope < requested scope: **Error** (cannot refine granularity)\n- Handles special cases:\n - Accelerator metrics (no aggregation)\n - Memory domain metrics\n - Multi-node jobs (per-node queries)\n\n**`HealthCheck()`** (query.go)\n```go\nfunc (ccms *InternalMetricStore) HealthCheck(\n cluster string,\n nodes []string,\n metrics []string,\n) (map[string]HealthCheckResult, error)\n```\n- Delegates to `ms.HealthCheck()`\n- Returns monitoring state per node (Full/Partial/Failed)\n\n### Relationship to MemoryStore\n\n| Aspect | InternalMetricStore | MemoryStore |\n|--------|---------------------|------------|\n| **Role** | Public API facade | Internal storage/retrieval |\n| **Instance** | Singleton (var MetricStoreHandle) | Singleton (msInstance) |\n| **Access** | Used by external packages | Only via InternalMetricStore |\n| **Methods** | High-level: LoadData, HealthCheck | Low-level: Write, Read, Free |\n| **Scope** | Job-centric, scope transformation | Metric-centric, raw storage |\n\n---\n\n## 4. KEY DATA STRUCTURES & RELATIONSHIPS\n\n### Hierarchical Tree Organization\n\n```\nMemoryStore\n└── root (Level)\n └── children[\"emmy\"] (cluster Level)\n └── metrics [buffer, buffer, ...] (node-level aggregates)\n └── children[\"node001\"] (host Level)\n └── metrics [buffer, buffer, ...]\n └── children[\"socket0\"] (Level)\n └── metrics [buffer, buffer, ...]\n └── children[\"core0\"] (Level)\n └── metrics [buffer, buffer, ...] (actual data)\n └── children[\"core1\"]\n └── metrics [buffer, buffer, ...]\n```\n\n### Buffer Chain (Linked List)\n\nTime ordering: oldest ← prev -- prev -- newest (head)\n\n```\n[start=1000] ← [start=1512] ← [start=2024] (head)\n data[512] data[512] data[42]\n```\n\n### Metrics Indexing\n\n- Each `Level.metrics` is a slice of `*buffer`\n- Index = `MetricConfig.offset` (assigned during `InitMetrics()`)\n- Example:\n ```\n Metrics map: {\"cpu_load\": {offset: 0}, \"mem_used\": {offset: 1}}\n Level.metrics: [*buffer for cpu_load, *buffer for mem_used]\n ```\n\n---\n\n## 5.

I have a complete picture. Let me design the plan.\n\n---\n\n## Implementation Plan: Consolidate Query-Building Logic\n\n### Summary of Differences Found\n\nAfter thorough analysis, here are all the concrete differences between the two implementations:\n\n**Structural differences:**\n1. `buildScopeQueries()` -- exists as a standalone function in `metricstoreclient`, inline in `metricstore`\n2. Scope dedup: `map[schema.MetricScope]bool` (metricstore) vs labeled-loop + `[]schema.MetricScope` (metricstoreclient)\n3. Topology access: inline `archive.GetSubCluster()` (metricstore) vs `getTopology()`/`getTopologyByNode()` with caching (metricstoreclient)\n\n**Functional differences:**\n4. **MemoryDomain -> Socket** transformation: present in `metricstoreclient/buildScopeQueries()` (lines 449-472), **missing** from `metricstore/buildQueries()` and `metricstore/buildNodeQueries()`\n5. `sanitizeStats` signature: `(data *APIMetricData)` in metricstore vs `(avg, min, max *schema.Float)` in metricstoreclient. The metricstoreclient version zeros ALL three if ANY is NaN; the metricstore version zeros each independently.\n\n**Type differences (not shareable without unification):**\n6. `APIQuery.Resolution`: `int64` (metricstore) vs `int` (metricstoreclient)\n7. `APIMetricData.Resolution`: `int64` vs `int`\n8. `APIMetricData.Data`: `schema.FloatArray` vs `[]schema.Float`\n9. `APIQuery.ScaleFactor`: present in metricstore, absent in metricstoreclient\n\n### Design Decisions\n\nGiven the constraints (separate `APIQuery` types, different resolution types, different data fetching), the plan focuses on what **can** be shared without large-scale type unification:\n\n**Share: `buildScopeQueries` logic** -- This is the highest-value target. It is pure scope-transformation logic that depends only on `schema.Topology`, `schema.MetricScope`, and string/int slices. It does NOT depend on `APIQuery` at all internally -- it only constructs the output fields.\n\n**Approach: Generic scope-query builder returning intermediate structs.** Create a shared package-level function that returns a simple intermediate type (not `APIQuery`), which each package then converts to its own `APIQuery`. This avoids coupling to either `APIQuery` type.\n\n**Alternative considered and rejected:** Making `buildScopeQueries` return `metricstoreclient.APIQuery` and importing it from `metricstore` -- this creates a wrong dependency direction (`pkg/` importing `internal/`). The reverse direction (moving to `pkg/`) is possible but `metricstoreclient` is an `internal/` package.\n\n**Best location for shared code:** A new file in `pkg/metricstore/` (e.g., `pkg/metricstore/scopequery.go`), since `metricstoreclient` already imports `pkg/metricstore`. Both packages can access code there.\n\n### Step-by-Step Plan\n\n#### Step 1: Define shared intermediate type and function in `pkg/metricstore/scopequery.go`\n\nCreate a new file `pkg/metricstore/scopequery.go` containing:\n\n```go\npackage metricstore\n\nimport \"github.com/ClusterCockpit/cc-lib/v2/schema\"\n\n// ScopeQueryResult holds the fields needed to construct an APIQuery for a single scope query.\n// This is a package-independent intermediate that both metricstore and metricstoreclient\n// can convert to their respective APIQuery types.\ntype ScopeQueryResult struct {\n Metric string\n Hostname string\n Aggregate bool\n Type *string // nil for node-scope queries\n TypeIds []string\n Scope schema.MetricScope // The assigned (actual) scope\n}\n\n// BuildScopeQueries generates scope query descriptors for a given scope transformation.\n// It returns (results, nil) on success, (empty, nil) for expected exceptions,\n// and (nil, error) for unhandled cases.\nfunc BuildScopeQueries(\n nativeScope, requestedScope schema.MetricScope,\n metric, hostname string,\n topology *schema.Topology,\n hwthreads []int,\n accelerators []string,\n) ([]ScopeQueryResult, error) {\n // ... (port from metricstoreclient/buildScopeQueries, \n // omitting Resolution since callers set it)\n}\n```\n\nKey design points:\n- `Resolution` is omitted from `ScopeQueryResult` because it differs in type (`int` vs `int64`) and callers always know it.\n- The function is exported so both packages can use it.\n- Move the scope string constants (`hwthreadString`, etc.) here as well -- both packages have identical copies.\n- Move `intToStringSlice` here -- both packages have copies (the metricstore version is slightly more optimized with buffer reuse, use that).\n- Include the **MemoryDomain -> Socket** transformation from metricstoreclient.\n\n#### Step 2: Update `pkg/metricstore/query.go`\n\nRefactor `buildQueries()` and `buildNodeQueries()`:\n- Replace the inline scope-transformation if-chain (lines 317-534 in `buildQueries`, lines 1099-1314 in `buildNodeQueries`) with a call to `BuildScopeQueries()`.\n- Convert each `ScopeQueryResult` to the local `APIQuery` by adding `Resolution: resolution`.\n- Handle the return value convention: empty slice = expected exception (continue), nil = error.\n- Remove the duplicated scope string constants and `intToStringSlice` (now in `scopequery.go`).\n- Switch dedup from `map[schema.MetricScope]bool` to the labeled-loop + slice pattern used in metricstoreclient (more consistent, avoids allocation for the typical 1-3 scopes).\n\nThis change also **adds the missing MemoryDomain -> Socket transformation** to the internal store.\n\n#### Step 3: Update `internal/metricstoreclient/cc-metric-store-queries.go`\n\nRefactor `buildQueries()` and `buildNodeQueries()`:\n- Replace call to local `buildScopeQueries()` with `metricstore.BuildScopeQueries()`.\n- Convert each `ScopeQueryResult` to the local `APIQuery` by adding `Resolution: resolution`.\n- Delete the local `buildScopeQueries()` function.\n- Delete the local scope string constants and `intToStringSlice` (now in `pkg/metricstore/scopequery.go`).\n\n#### Step 4: Synchronize `sanitizeStats`\n\nTwo options:\n\n**Option A (recommended -- minimal change):** Align the metricstore `sanitizeStats` to match the metricstoreclient behavior (zero ALL if ANY is NaN). This is the safer behavior since partial NaN stats are likely corrupt. Change `pkg/metricstore/query.go` `sanitizeStats` to:\n```go\nfunc sanitizeStats(data *APIMetricData) {\n if data.Avg.IsNaN() || data.Min.IsNaN() || data.Max.IsNaN() {\n data.Avg = schema.Float(0)\n data.Min = schema.Float(0)\n data.Max = schema.Float(0)\n }\n}\n```\n\nDo NOT share the function itself since the signatures differ due to different `APIMetricData` types. Just synchronize the logic.\n\n**Option B:** Extract a shared `SanitizeStats(avg, min, max *schema.Float)` into `pkg/metricstore/scopequery.go` and have both call it. The metricstore version would wrap it:\n```go\nfunc sanitizeStats(data *APIMetricData) {\n metricstore.SanitizeStats(&data.Avg, &data.Min, &data.Max)\n}\n```\nThis is cleaner but adds an extra function call. Low cost, reasonable.\n\nI recommend **Option B** for consistency.\n\n#### Step 5: Add `hasNaNStats` to shared code (optional)\n\nMove `hasNaNStats` to `pkg/metricstore/scopequery.go` as an exported function. Currently only used in `metricstoreclient/LoadStats`, but `metricstore/LoadStats` has the same check inline (line 602). Both can use the shared version.\n\n#### Step 6: Add tests for `BuildScopeQueries`\n\nCreate `pkg/metricstore/scopequery_test.go` with table-driven tests covering all scope transformation cases, including the MemoryDomain -> Socket case. This is currently untested in both packages.\n\n### What NOT to share (and why)\n\n- **`buildQueries` / `buildNodeQueries` themselves**: These differ in topology access patterns (caching vs inline), empty-resource checks, and are methods on different receiver types. The shared `BuildScopeQueries` extracts the core logic while letting each package handle its own orchestration.\n- **`APIQuery` / `APIMetricData` types**: Different `Resolution` types (`int` vs `int64`), different `Data` types (`schema.FloatArray` vs `[]schema.Float`), and `ScaleFactor` only in internal. Unifying would require touching too much code across both packages for marginal benefit.\n- **Load* functions**: They share the same result-processing pattern but depend on package-specific types (`APIQuery`, `APIMetricData`) and fetching mechanisms (`FetchData` vs `doRequest`). Extracting generic result processors would require generics or interfaces that add complexity without proportional benefit.\n\n### Migration sequence\n\n1. Create `pkg/metricstore/scopequery.go` with `ScopeQueryResult`, `BuildScopeQueries`, `IntToStringSlice`, `SanitizeStats`, and scope string constants.\n2. Add `pkg/metricstore/scopequery_test.go`.\n3. Update `pkg/metricstore/query.go` to use the shared functions. Run `go test ./pkg/metricstore/...`.\n4. Update `internal/metricstoreclient/cc-metric-store-queries.go` to use the shared functions. Run `go test ./internal/metricstoreclient/...` (currently no tests, but compile check).\n5. Run full test suite: `make test`.\n\n### Risks and mitigations\n\n- **MemoryDomain -> Socket addition to internal store**: This is a functional change. The internal store previously returned an error for this case. The metricstoreclient handles it correctly. Adding it is a bug fix, not a regression.\n- **sanitizeStats behavior change**: Changing from \"zero each independently\" to \"zero all if any is NaN\" could change output for edge cases where only one stat is NaN. This is arguably more correct (partial NaN stats are suspect). Low risk.\n- **Import cycle risk**: None. `internal/metricstoreclient` already imports `pkg/metricstore`. The shared code goes into `pkg/metricstore`, which does not import `internal/metricstoreclient`.\n\n### Critical Files for Implementation\n- `/Users/jan/prg/ClusterCockpit/cc-backend/pkg/metricstore/query.go` - Contains the inline scope transformation to replace with shared BuildScopeQueries calls; also buildQueries and buildNodeQueries to refactor\n- `/Users/jan/prg/ClusterCockpit/cc-backend/internal/metricstoreclient/cc-metric-store-queries.go` - Contains the reference buildScopeQueries implementation to extract; buildQueries and buildNodeQueries to refactor\n- `/Users/jan/prg/ClusterCockpit/cc-backend/pkg/metricstore/api.go` - Defines the internal APIQuery/APIMetricData types; context for type differences\n- `/Users/jan/prg/ClusterCockpit/cc-backend/internal/metricstoreclient/cc-metric-store.go` - Defines external APIQuery/APIMetricData types and Load* functions with result processing to synchronize\n- `/Users/jan/prg/ClusterCockpit/cc-backend/internal/metricdispatch/metricdata.go` - The MetricDataRepository interface both packages implement; must not be broken"},{"type":"text","text":"agentId: aeb62a7c5fea57dd2 (for resuming to continue this agent's work if needed)\ntotal_tokens: 65135\ntool_uses: 15\nduration_ms: 102215"}]}]},"uuid":"f87f9792-0acc-4409-b718-c7eb078f209d","timestamp":"2026-03-04T15:26:58.686Z","toolUseResult":{"status":"completed","prompt":"I need to design a plan to synchronize and consolidate the query-building logic between two packages that implement the same MetricDataRepository interface:\n\n## Context\n\n1. **`pkg/metricstore/query.go`** (InternalMetricStore) — in-memory metric store\n2. **`internal/metricstoreclient/cc-metric-store-queries.go`** (CCMetricStore) — HTTP client to external cc-metric-store\n\nBoth implement the `MetricDataRepository` interface from `internal/metricdispatch/metricdata.go`.\n\n## Key Differences Found\n\n### buildQueries differences:\n- **pkg/metricstore**: Inline scope transformation (long chain of if-statements in the inner loop).

Let me design the plan.\n\n---\n\n## Implementation Plan: Consolidate Query-Building Logic\n\n### Summary of Differences Found\n\nAfter thorough analysis, here are all the concrete differences between the two implementations:\n\n**Structural differences:**\n1. `buildScopeQueries()` -- exists as a standalone function in `metricstoreclient`, inline in `metricstore`\n2. Scope dedup: `map[schema.MetricScope]bool` (metricstore) vs labeled-loop + `[]schema.MetricScope` (metricstoreclient)\n3. Topology access: inline `archive.GetSubCluster()` (metricstore) vs `getTopology()`/`getTopologyByNode()` with caching (metricstoreclient)\n\n**Functional differences:**\n4. **MemoryDomain -> Socket** transformation: present in `metricstoreclient/buildScopeQueries()` (lines 449-472), **missing** from `metricstore/buildQueries()` and `metricstore/buildNodeQueries()`\n5. `sanitizeStats` signature: `(data *APIMetricData)` in metricstore vs `(avg, min, max *schema.Float)` in metricstoreclient. The metricstoreclient version zeros ALL three if ANY is NaN; the metricstore version zeros each independently.\n\n**Type differences (not shareable without unification):**\n6. `APIQuery.Resolution`: `int64` (metricstore) vs `int` (metricstoreclient)\n7. `APIMetricData.Resolution`: `int64` vs `int`\n8. `APIMetricData.Data`: `schema.FloatArray` vs `[]schema.Float`\n9. `APIQuery.ScaleFactor`: present in metricstore, absent in metricstoreclient\n\n### Design Decisions\n\nGiven the constraints (separate `APIQuery` types, different resolution types, different data fetching), the plan focuses on what **can** be shared without large-scale type unification:\n\n**Share: `buildScopeQueries` logic** -- This is the highest-value target. It is pure scope-transformation logic that depends only on `schema.Topology`, `schema.MetricScope`, and string/int slices. It does NOT depend on `APIQuery` at all internally -- it only constructs the output fields.\n\n**Approach: Generic scope-query builder returning intermediate structs.** Create a shared package-level function that returns a simple intermediate type (not `APIQuery`), which each package then converts to its own `APIQuery`. This avoids coupling to either `APIQuery` type.\n\n**Alternative considered and rejected:** Making `buildScopeQueries` return `metricstoreclient.APIQuery` and importing it from `metricstore` -- this creates a wrong dependency direction (`pkg/` importing `internal/`). The reverse direction (moving to `pkg/`) is possible but `metricstoreclient` is an `internal/` package.\n\n**Best location for shared code:** A new file in `pkg/metricstore/` (e.g., `pkg/metricstore/scopequery.go`), since `metricstoreclient` already imports `pkg/metricstore`. Both packages can access code there.\n\n### Step-by-Step Plan\n\n#### Step 1: Define shared intermediate type and function in `pkg/metricstore/scopequery.go`\n\nCreate a new file `pkg/metricstore/scopequery.go` containing:\n\n```go\npackage metricstore\n\nimport \"github.com/ClusterCockpit/cc-lib/v2/schema\"\n\n// ScopeQueryResult holds the fields needed to construct an APIQuery for a single scope query.\n// This is a package-independent intermediate that both metricstore and metricstoreclient\n// can convert to their respective APIQuery types.\ntype ScopeQueryResult struct {\n Metric string\n Hostname string\n Aggregate bool\n Type *string // nil for node-scope queries\n TypeIds []string\n Scope schema.MetricScope // The assigned (actual) scope\n}\n\n// BuildScopeQueries generates scope query descriptors for a given scope transformation.\n// It returns (results, nil) on success, (empty, nil) for expected exceptions,\n// and (nil, error) for unhandled cases.\nfunc BuildScopeQueries(\n nativeScope, requestedScope schema.MetricScope,\n metric, hostname string,\n topology *schema.Topology,\n hwthreads []int,\n accelerators []string,\n) ([]ScopeQueryResult, error) {\n // ... (port from metricstoreclient/buildScopeQueries, \n // omitting Resolution since callers set it)\n}\n```\n\nKey design points:\n- `Resolution` is omitted from `ScopeQueryResult` because it differs in type (`int` vs `int64`) and callers always know it.\n- The function is exported so both packages can use it.\n- Move the scope string constants (`hwthreadString`, etc.) here as well -- both packages have identical copies.\n- Move `intToStringSlice` here -- both packages have copies (the metricstore version is slightly more optimized with buffer reuse, use that).\n- Include the **MemoryDomain -> Socket** transformation from metricstoreclient.\n\n#### Step 2: Update `pkg/metricstore/query.go`\n\nRefactor `buildQueries()` and `buildNodeQueries()`:\n- Replace the inline scope-transformation if-chain (lines 317-534 in `buildQueries`, lines 1099-1314 in `buildNodeQueries`) with a call to `BuildScopeQueries()`.\n- Convert each `ScopeQueryResult` to the local `APIQuery` by adding `Resolution: resolution`.\n- Handle the return value convention: empty slice = expected exception (continue), nil = error.\n- Remove the duplicated scope string constants and `intToStringSlice` (now in `scopequery.go`).\n- Switch dedup from `map[schema.MetricScope]bool` to the labeled-loop + slice pattern used in metricstoreclient (more consistent, avoids allocation for the typical 1-3 scopes).\n\nThis change also **adds the missing MemoryDomain -> Socket transformation** to the internal store.\n\n#### Step 3: Update `internal/metricstoreclient/cc-metric-store-queries.go`\n\nRefactor `buildQueries()` and `buildNodeQueries()`:\n- Replace call to local `buildScopeQueries()` with `metricstore.BuildScopeQueries()`.\n- Convert each `ScopeQueryResult` to the local `APIQuery` by adding `Resolution: resolution`.\n- Delete the local `buildScopeQueries()` function.\n- Delete the local scope string constants and `intToStringSlice` (now in `pkg/metricstore/scopequery.go`).\n\n#### Step 4: Synchronize `sanitizeStats`\n\nTwo options:\n\n**Option A (recommended -- minimal change):** Align the metricstore `sanitizeStats` to match the metricstoreclient behavior (zero ALL if ANY is NaN). This is the safer behavior since partial NaN stats are likely corrupt. Change `pkg/metricstore/query.go` `sanitizeStats` to:\n```go\nfunc sanitizeStats(data *APIMetricData) {\n if data.Avg.IsNaN() || data.Min.IsNaN() || data.Max.IsNaN() {\n data.Avg = schema.Float(0)\n data.Min = schema.Float(0)\n data.Max = schema.Float(0)\n }\n}\n```\n\nDo NOT share the function itself since the signatures differ due to different `APIMetricData` types. Just synchronize the logic.\n\n**Option B:** Extract a shared `SanitizeStats(avg, min, max *schema.Float)` into `pkg/metricstore/scopequery.go` and have both call it. The metricstore version would wrap it:\n```go\nfunc sanitizeStats(data *APIMetricData) {\n metricstore.SanitizeStats(&data.Avg, &data.Min, &data.Max)\n}\n```\nThis is cleaner but adds an extra function call. Low cost, reasonable.\n\nI recommend **Option B** for consistency.\n\n#### Step 5: Add `hasNaNStats` to shared code (optional)\n\nMove `hasNaNStats` to `pkg/metricstore/scopequery.go` as an exported function. Currently only used in `metricstoreclient/LoadStats`, but `metricstore/LoadStats` has the same check inline (line 602). Both can use the shared version.\n\n#### Step 6: Add tests for `BuildScopeQueries`\n\nCreate `pkg/metricstore/scopequery_test.go` with table-driven tests covering all scope transformation cases, including the MemoryDomain -> Socket case. This is currently untested in both packages.\n\n### What NOT to share (and why)\n\n- **`buildQueries` / `buildNodeQueries` themselves**: These differ in topology access patterns (caching vs inline), empty-resource checks, and are methods on different receiver types. The shared `BuildScopeQueries` extracts the core logic while letting each package handle its own orchestration.\n- **`APIQuery` / `APIMetricData` types**: Different `Resolution` types (`int` vs `int64`), different `Data` types (`schema.FloatArray` vs `[]schema.Float`), and `ScaleFactor` only in internal. Unifying would require touching too much code across both packages for marginal benefit.\n- **Load* functions**: They share the same result-processing pattern but depend on package-specific types (`APIQuery`, `APIMetricData`) and fetching mechanisms (`FetchData` vs `doRequest`). Extracting generic result processors would require generics or interfaces that add complexity without proportional benefit.\n\n### Migration sequence\n\n1. Create `pkg/metricstore/scopequery.go` with `ScopeQueryResult`, `BuildScopeQueries`, `IntToStringSlice`, `SanitizeStats`, and scope string constants.\n2. Add `pkg/metricstore/scopequery_test.go`.\n3. Update `pkg/metricstore/query.go` to use the shared functions. Run `go test ./pkg/metricstore/...`.\n4. Update `internal/metricstoreclient/cc-metric-store-queries.go` to use the shared functions. Run `go test ./internal/metricstoreclient/...` (currently no tests, but compile check).\n5. Run full test suite: `make test`.\n\n### Risks and mitigations\n\n- **MemoryDomain -> Socket addition to internal store**: This is a functional change. The internal store previously returned an error for this case. The metricstoreclient handles it correctly. Adding it is a bug fix, not a regression.\n- **sanitizeStats behavior change**: Changing from \"zero each independently\" to \"zero all if any is NaN\" could change output for edge cases where only one stat is NaN. This is arguably more correct (partial NaN stats are suspect). Low risk.\n- **Import cycle risk**: None. `internal/metricstoreclient` already imports `pkg/metricstore`. The shared code goes into `pkg/metricstore`, which does not import `internal/metricstoreclient`.\n\n### Critical Files for Implementation\n- `/Users/jan/prg/ClusterCockpit/cc-backend/pkg/metricstore/query.go` - Contains the inline scope transformation to replace with shared BuildScopeQueries calls; also buildQueries and buildNodeQueries to refactor\n- `/Users/jan/prg/ClusterCockpit/cc-backend/internal/metricstoreclient/cc-metric-store-queries.go` - Contains the reference buildScopeQueries implementation to extract; buildQueries and buildNodeQueries to refactor\n- `/Users/jan/prg/ClusterCockpit/cc-backend/pkg/metricstore/api.go` - Defines the internal APIQuery/APIMetricData types; context for type differences\n- `/Users/jan/prg/ClusterCockpit/cc-backend/internal/metricstoreclient/cc-metric-store.go` - Defines external APIQuery/APIMetricData types and Load* functions with result processing to synchronize\n- `/Users/jan/prg/ClusterCockpit/cc-backend/internal/metricdispatch/metricdata.go` - The MetricDataRepository interface both packages implement; must not be broken"}],"totalDurationMs":102215,"totalTokens":65135,"totalToolUseCount":15,"usage":{"input_tokens":1,"cache_creation_input_tokens":919,"cache_read_input_tokens":61210,"output_tokens":3005,"server_tool_use":{"web_search_requests":0,"web_fetch_requests":0},"service_tier":"standard","cache_creation":{"ephemeral_1h_input_tokens":919,"ephemeral_5m_input_tokens":0},"inference_geo":"","iterations":[],"speed":"standard"}},"sourceToolAssistantUUID":"ff830631-3e76-4c5a-9a43-d0ae540820df"} +{"parentUuid":"f87f9792-0acc-4409-b718-c7eb078f209d","isSidechain":false,"userType":"external","cwd":"/Users/jan/prg/ClusterCockpit/cc-backend","sessionId":"eec1fc87-d8f6-42f6-b296-d7a2f79af002","version":"2.1.66","gitBranch":"dev","slug":"curious-dancing-nebula","message":{"model":"claude-opus-4-6","id":"msg_01YLjMEvaoXL9SrqMHicbYqj","type":"message","role":"assistant","content":[{"type":"text","text":"\n\nNow let me write the final plan."}],"stop_reason":null,"stop_sequence":null,"usage":{"input_tokens":3,"cache_creation_input_tokens":4166,"cache_read_input_tokens":85789,"cache_creation":{"ephemeral_5m_input_tokens":0,"ephemeral_1h_input_tokens":4166},"output_tokens":2,"service_tier":"standard","inference_geo":"not_available"}},"requestId":"req_011CYiGtrFaRNc8doYxZZcxa","type":"assistant","uuid":"9b7ea6f4-8555-44c9-bc2c-d3bcde1efaf4","timestamp":"2026-03-04T15:27:02.321Z"} +{"parentUuid":"9b7ea6f4-8555-44c9-bc2c-d3bcde1efaf4","isSidechain":false,"userType":"external","cwd":"/Users/jan/prg/ClusterCockpit/cc-backend","sessionId":"eec1fc87-d8f6-42f6-b296-d7a2f79af002","version":"2.1.66","gitBranch":"dev","slug":"curious-dancing-nebula","message":{"model":"claude-opus-4-6","id":"msg_01YLjMEvaoXL9SrqMHicbYqj","type":"message","role":"assistant","content":[{"type":"tool_use","id":"toolu_01XP2qtCAUXbCvMSDxcTbeYx","name":"Write","input":{"file_path":"/Users/jan/.claude/plans/curious-dancing-nebula.md","content":"# Consolidate buildQueries / Scope Transformation Logic\n\n## Context\n\n`pkg/metricstore/query.go` (InternalMetricStore) and `internal/metricstoreclient/cc-metric-store-queries.go` (CCMetricStore) both implement the `MetricDataRepository` interface.

Return a package-independent intermediate type (`ScopeQueryResult`) that each package converts to its own `APIQuery` — this avoids coupling the two different `APIQuery` types (they differ in `Resolution` type: `int64` vs `int`, and internal has `ScaleFactor`).\n\n## Steps\n\n### 1. Create `pkg/metricstore/scopequery.go`\n\nNew file containing:\n\n- **`ScopeQueryResult`** struct — intermediate type with fields: `Metric`, `Hostname`, `Aggregate`, `Type *string`, `TypeIds []string`, `Scope schema.MetricScope` (no Resolution — callers set it)\n- **`BuildScopeQueries()`** — exported function ported from `metricstoreclient/buildScopeQueries()` (lines 257-517), returning `([]ScopeQueryResult, error)`. Returns empty slice for expected exceptions, error for unhandled cases\n- **Scope string constants** — `HWThreadString`, `CoreString`, `MemoryDomainString`, `SocketString`, `AcceleratorString` (exported, move from both packages)\n- **`IntToStringSlice()`** — exported, using the optimized buffer-reuse version from metricstore\n- **`SanitizeStats(avg, min, max *schema.Float)`** — exported, using the metricstoreclient behavior (zero ALL if ANY is NaN)\n\n### 2. Update `pkg/metricstore/query.go`\n\n- Replace inline if-chain in `buildQueries()` (lines 317-534) with call to `BuildScopeQueries()`, converting each `ScopeQueryResult` → local `APIQuery` (adding `Resolution`)\n- Replace inline if-chain in `buildNodeQueries()` (lines 1099-1316) with same pattern\n- Delete local scope string constants, `intToStringSlice`, local `sanitizeStats`\n- Update `sanitizeStats` calls in `LoadData`/`LoadScopedStats`/`LoadNodeData`/`LoadNodeListData` to use `SanitizeStats(&res.Avg, &res.Min, &res.Max)`\n- Switch scope dedup from `map[schema.MetricScope]bool` to labeled-loop + slice (matches metricstoreclient, avoids allocation for typical 1-3 scopes)\n- This **adds the missing MemoryDomain → Socket transformation** to the internal store\n\n### 3. Update `internal/metricstoreclient/cc-metric-store-queries.go`\n\n- Replace call to local `buildScopeQueries()` with `metricstore.BuildScopeQueries()`, converting each `ScopeQueryResult` → local `APIQuery` (adding `Resolution`)\n- Delete local `buildScopeQueries()` function\n- Delete local scope string constants and `intToStringSlice`\n- Update `sanitizeStats` in `cc-metric-store.go` to call `metricstore.SanitizeStats()`\n\n### 4. Add tests: `pkg/metricstore/scopequery_test.go`\n\nTable-driven tests for `BuildScopeQueries` covering all transformation cases:\n- Same-scope (HWThread→HWThread, Core→Core, Socket→Socket, Node→Node, etc.)\n- Aggregation (HWThread→Core, HWThread→Socket, HWThread→Node, Core→Socket, Core→Node, etc.)\n- Accelerator cases (Accelerator→Accelerator, Accelerator→Node)\n- MemoryDomain cases including MemoryDomain→Socket\n- Unhandled case returns error\n\n## Files Modified\n\n| File | Action |\n|------|--------|\n| `pkg/metricstore/scopequery.go` | **New** — shared types and functions |\n| `pkg/metricstore/scopequery_test.go` | **New** — tests for BuildScopeQueries |\n| `pkg/metricstore/query.go` | Refactor buildQueries/buildNodeQueries to use BuildScopeQueries; remove duplicated helpers |\n| `internal/metricstoreclient/cc-metric-store-queries.go` | Replace local buildScopeQueries with shared; remove duplicated helpers |\n| `internal/metricstoreclient/cc-metric-store.go` | Update sanitizeStats to use shared SanitizeStats |\n\n## What is NOT shared (intentionally)\n\n- **`APIQuery`/`APIMetricData` types** — different Resolution types, Data types, ScaleFactor field\n- **`buildQueries`/`buildNodeQueries` themselves** — different topology access (caching vs inline), different receiver types\n- **Load* result-processing functions** — depend on package-specific types and fetch mechanisms\n\n## Verification\n\n1. `go build ./...` — compile check\n2. `go test ./pkg/metricstore/...` — existing + new scopequery tests\n3. `go test ./internal/metricstoreclient/...` — compile check\n4. `make test` — full test suite\n"},"caller":{"type":"direct"}}],"stop_reason":"tool_use","stop_sequence":null,"usage":{"input_tokens":1,"cache_creation_input_tokens":1705,"cache_read_input_tokens":89955,"output_tokens":38,"server_tool_use":{"web_search_requests":0,"web_fetch_requests":0},"service_tier":"standard","cache_creation":{"ephemeral_1h_input_tokens":1705,"ephemeral_5m_input_tokens":0},"inference_geo":"","iterations":[],"speed":"standard"}},"requestId":"req_011CYiGvpHozAszC5Q8XpAQF","type":"assistant","uuid":"1835697e-dd3c-497f-9c3e-2a48bc029c65","timestamp":"2026-03-04T15:27:28.208Z"} +{"parentUuid":"1835697e-dd3c-497f-9c3e-2a48bc029c65","isSidechain":false,"userType":"external","cwd":"/Users/jan/prg/ClusterCockpit/cc-backend","sessionId":"eec1fc87-d8f6-42f6-b296-d7a2f79af002","version":"2.1.66","gitBranch":"dev","slug":"curious-dancing-nebula","type":"user","message":{"role":"user","content":[{"type":"tool_result","content":"The user doesn't want to proceed with this tool use.

Remove redundant inner bounds checks in `LoadData` and `LoadNodeListData`\n\nThe outer truncation (e.g., lines 120-129 in internal `LoadData`) already ensures bounds safety, making the inner `if i >= len(...)` check dead code. Remove the inner checks.\n\n**Files (4 occurrences — 2 in each package):**\n- `pkg/metricstore/query.go` — `LoadData` (lines 131-137), `LoadNodeListData` (lines 696-702)\n- `internal/metricstoreclient/cc-metric-store.go` — `LoadData` (lines 278-283), `LoadNodeListData` (lines 682-688)\n\n### 7. Add capacity hint for `assignedScope` in internal `buildQueries`/`buildNodeQueries`\n\n**File:** `pkg/metricstore/query.go:254,822`\n\nChange `assignedScope := []schema.MetricScope{}` to use `make()` with matching capacity.\n\n### 8. Add bounds check to `LoadStats` for consistency (both packages)\n\n`LoadStats` indexes `req.Queries[i]` without checking bounds, unlike all other Load functions. Add a check.\n\n**Files:**\n- `pkg/metricstore/query.go:376`\n- `internal/metricstoreclient/cc-metric-store.go:395`\n\n## Verification\n\n1. `go build ./...` — ensure compilation succeeds\n2. `go test ./pkg/metricstore/...` — run metricstore tests\n3. `go test ./internal/metricstoreclient/...` — run client tests\n4. `go vet ./pkg/metricstore/... ./internal/metricstoreclient/...` — check for issues\n"} +{"parentUuid":"1b4af328-8505-4c6a-b2d4-9c102454705c","isSidechain":false,"userType":"external","cwd":"/Users/jan/prg/ClusterCockpit/cc-backend","sessionId":"2c26c946-1def-45ad-aac8-f65c4765658b","version":"2.1.68","gitBranch":"dev","slug":"warm-floating-scone","message":{"model":"claude-opus-4-6","id":"msg_011g9AfQBbpziMeRAKPETsBo","type":"message","role":"assistant","content":[{"type":"thinking","thinking":"Let me start by reading the relevant files to understand the current code before making changes.","signature":"EogCCkYICxgCKkBW59RCY6tGSB56nAGA//z3lRvJEDn5iJLOClMZGjxNRiWuAGiCmaIgNTdta1Sy/TNzx1kW0Sge7rGR/PxRSRnzEgzVWMKKRnGC7F5gVQ8aDB6IRgIGLUck+mUAMiIwPXSOdENPofnHH9C37ntJ46QPY4BzS6csCErH0oBdUdwdHWREsXjnRxmDPUwveX44KnBZq7rE/ucs/NLtbve7FsWyZDGfGNx4ZjUMDIu8FXayWkk/mgTVUREaEua4Wq+iLifqOh7XyOWmdPdP6hWeqLgZok0w5xWaXSdVlPcdSNOa45s5wW+0+MiAPlM5CVjU7eU9PEMAJ4lRdjI1NYPgS1GxGAE="}],"stop_reason":null,"stop_sequence":null,"usage":{"input_tokens":3,"cache_creation_input_tokens":5219,"cache_read_input_tokens":20208,"cache_creation":{"ephemeral_5m_input_tokens":0,"ephemeral_1h_input_tokens":5219},"output_tokens":10,"service_tier":"standard","inference_geo":"not_available"}},"requestId":"req_011CYiM3Z8ehPsB12AQ62uTR","type":"assistant","uuid":"d7ac8dff-17df-4dda-a199-64a0acff57ff","timestamp":"2026-03-04T16:21:27.002Z"} +{"parentUuid":"d7ac8dff-17df-4dda-a199-64a0acff57ff","isSidechain":false,"userType":"external","cwd":"/Users/jan/prg/ClusterCockpit/cc-backend","sessionId":"2c26c946-1def-45ad-aac8-f65c4765658b","version":"2.1.68","gitBranch":"dev","slug":"warm-floating-scone","message":{"model":"claude-opus-4-6","id":"msg_011g9AfQBbpziMeRAKPETsBo","type":"message","role":"assistant","content":[{"type":"text","text":"I'll start by reading the key files to understand the current code."}],"stop_reason":null,"stop_sequence":null,"usage":{"input_tokens":3,"cache_creation_input_tokens":5219,"cache_read_input_tokens":20208,"cache_creation":{"ephemeral_5m_input_tokens":0,"ephemeral_1h_input_tokens":5219},"output_tokens":10,"service_tier":"standard","inference_geo":"not_available"}},"requestId":"req_011CYiM3Z8ehPsB12AQ62uTR","type":"assistant","uuid":"9d93b803-a9c4-4b1f-8066-2aa3a3ce854d","timestamp":"2026-03-04T16:21:27.552Z"} +{"parentUuid":"9d93b803-a9c4-4b1f-8066-2aa3a3ce854d","isSidechain":false,"userType":"external","cwd":"/Users/jan/prg/ClusterCockpit/cc-backend","sessionId":"2c26c946-1def-45ad-aac8-f65c4765658b","version":"2.1.68","gitBranch":"dev","slug":"warm-floating-scone","message":{"model":"claude-opus-4-6","id":"msg_011g9AfQBbpziMeRAKPETsBo","type":"message","role":"assistant","content":[{"type":"tool_use","id":"toolu_01KoYLbsxdKoLzHRtxpeDnCJ","name":"Read","input":{"file_path":"/Users/jan/prg/ClusterCockpit/cc-backend/pkg/metricstore/query.go"},"caller":{"type":"direct"}}],"stop_reason":null,"stop_sequence":null,"usage":{"input_tokens":3,"cache_creation_input_tokens":5219,"cache_read_input_tokens":20208,"cache_creation":{"ephemeral_5m_input_tokens":0,"ephemeral_1h_input_tokens":5219},"output_tokens":10,"service_tier":"standard","inference_geo":"not_available"}},"requestId":"req_011CYiM3Z8ehPsB12AQ62uTR","type":"assistant","uuid":"5a8d3ec0-23f6-42ad-9bf7-dc28fd089d24","timestamp":"2026-03-04T16:21:28.585Z"} +{"parentUuid":"5a8d3ec0-23f6-42ad-9bf7-dc28fd089d24","isSidechain":false,"userType":"external","cwd":"/Users/jan/prg/ClusterCockpit/cc-backend","sessionId":"2c26c946-1def-45ad-aac8-f65c4765658b","version":"2.1.68","gitBranch":"dev","slug":"warm-floating-scone","type":"progress","data":{"type":"hook_progress","hookEvent":"PostToolUse","hookName":"PostToolUse:Read","command":"callback"},"parentToolUseID":"toolu_01KoYLbsxdKoLzHRtxpeDnCJ","toolUseID":"toolu_01KoYLbsxdKoLzHRtxpeDnCJ","timestamp":"2026-03-04T16:21:28.771Z","uuid":"2739bf37-bec1-4dbf-9591-e5de067de986"} +{"parentUuid":"5a8d3ec0-23f6-42ad-9bf7-dc28fd089d24","isSidechain":false,"userType":"external","cwd":"/Users/jan/prg/ClusterCockpit/cc-backend","sessionId":"2c26c946-1def-45ad-aac8-f65c4765658b","version":"2.1.68","gitBranch":"dev","slug":"warm-floating-scone","type":"user","message":{"role":"user","content":[{"tool_use_id":"toolu_01KoYLbsxdKoLzHRtxpeDnCJ","type":"tool_result","content":" 1→// Copyright (C) NHR@FAU, University Erlangen-Nuremberg.\n 2→// All rights reserved.

metricstoreclient provides a client for querying the cc-metric-store time series database.\n//\n// The cc-metric-store is a high-performance time series database optimized for HPC metric data.\n// This client handles HTTP communication, query construction, scope transformations, and data retrieval\n// for job and node metrics across different metric scopes (node, socket, core, hwthread, accelerator).\n//\n// # Architecture\n//\n// The package is split into two main components:\n// - Client Operations (cc-metric-store.go): HTTP client, request handling, data loading methods\n// - Query Building (cc-metric-store-queries.go): Query construction and scope transformation logic\n//\n// # Basic Usage\n//\n//\tstore := NewCCMetricStore(\"http://localhost:8080\", \"jwt-token\")\n//\n//\t// Load job data\n//\tjobData, err := store.LoadData(job, metrics, scopes, ctx, resolution)\n//\tif err != nil {\n//\t log.Fatal(err)\n//\t}\n//\n// # Metric Scopes\n//\n// The client supports hierarchical metric scopes that map to HPC hardware topology:\n// - MetricScopeAccelerator: GPU/accelerator level metrics\n// - MetricScopeHWThread: Hardware thread (SMT) level metrics\n// - MetricScopeCore: CPU core level metrics\n// - MetricScopeSocket: CPU socket level metrics\n// - MetricScopeMemoryDomain: NUMA domain level metrics\n// - MetricScopeNode: Full node level metrics\n//\n// The client automatically handles scope transformations, aggregating finer-grained metrics\n// to coarser scopes when needed (e.g., aggregating core metrics to socket level).\n//\n// # Error Handling\n//\n// The client supports partial errors - if some queries fail, it returns both the successful\n// data and an error listing the failed queries. This allows processing partial results\n// when some nodes or metrics are temporarily unavailable.\n//\n// # API Versioning\n//\n// The client uses cc-metric-store API v2, which includes support for:\n// - Data resampling for bandwidth optimization\n// - Multi-scope queries in a single request\n// - Aggregation across hardware topology levels\npackage metricstoreclient\n\nimport

high-performance time series database optimized for HPC metric data.\n// This client handles HTTP communication, query construction, scope transformations, and data retrieval\n// for job and node metrics across different metric scopes (node, socket, core, hwthread, accelerator).\n//\n// # Architecture\n//\n// The package is split into two main components:\n// - Client Operations (cc-metric-store.go): HTTP client, request handling, data loading methods\n// - Query Building (cc-metric-store-queries.go): Query construction and scope transformation logic\n//\n// # Basic Usage\n//\n//\tstore := NewCCMetricStore(\"http://localhost:8080\", \"jwt-token\")\n//\n//\t// Load job data\n//\tjobData, err := store.LoadData(job, metrics, scopes, ctx, resolution)\n//\tif err !=

metrics\n// - MetricScopeHWThread: Hardware thread (SMT) level metrics\n// - MetricScopeCore: CPU core level metrics\n// - MetricScopeSocket: CPU socket level metrics\n// - MetricScopeMemoryDomain: NUMA domain level metrics\n// - MetricScopeNode: Full node level metrics\n//\n// The client automatically handles scope transformations, aggregating finer-grained metrics\n// to coarser scopes when needed (e.g., aggregating core metrics to socket level).\n//\n// # Error Handling\n//\n// The client supports partial errors - if some queries fail, it returns both the successful\n// data and an error listing the failed queries. This allows processing partial results\n// when some nodes or metrics are temporarily unavailable.\n//\n// # API Versioning\n//\n// The client uses cc-metric-store API v2, which includes support for:\n// - Data resampling for bandwidth optimization\n// - Multi-scope queries in a single request\n// - Aggregation across hardware topology levels\npackage metricstoreclient\n\nimport

database.\n//\n// The cc-metric-store is a high-performance time series database optimized for HPC metric data.\n// This client handles HTTP communication, query construction, scope transformations, and data retrieval\n// for job and node metrics across different metric scopes (node, socket, core, hwthread, accelerator).\n//\n// # Architecture\n//\n// The package is split into two main components:\n// - Client Operations (cc-metric-store.go): HTTP client, request handling, data loading methods\n// - Query Building (cc-metric-store-queries.go): Query construction and scope transformation logic\n//\n// # Basic Usage\n//\n//\tstore := NewCCMetricStore(\"http://localhost:8080\", \"jwt-token\")\n//\n//\t// Load job data\n//\tjobData, err := store.LoadData(job, metrics,

MetricScopeAccelerator: GPU/accelerator level metrics\n// - MetricScopeHWThread: Hardware thread (SMT) level metrics\n// - MetricScopeCore: CPU core level metrics\n// - MetricScopeSocket: CPU socket level metrics\n// - MetricScopeMemoryDomain: NUMA domain level metrics\n// - MetricScopeNode: Full node level metrics\n//\n// The client automatically handles scope transformations, aggregating finer-grained metrics\n// to coarser scopes when needed (e.g., aggregating core metrics to socket level).\n//\n// # Error Handling\n//\n// The client supports partial errors - if some queries fail, it returns both the successful\n// data and an error listing the failed queries. This allows processing partial results\n// when some nodes or metrics are temporarily unavailable.\n//\n// # API Versioning\n//\n// The client uses cc-metric-store API v2, which includes support for:\n// - Data resampling for bandwidth optimization\n// - Multi-scope queries in a single request\n// - Aggregation across hardware topology levels\npackage metricstoreclient\n\nimport

database optimized for HPC metric data.\n// This client handles HTTP communication, query construction, scope transformations, and data retrieval\n// for job and node metrics across different metric scopes (node, socket, core, hwthread, accelerator).\n//\n// # Architecture\n//\n// The package is split into two main components:\n// - Client Operations (cc-metric-store.go): HTTP client, request handling, data loading methods\n// - Query Building (cc-metric-store-queries.go): Query construction and scope transformation logic\n//\n// # Basic Usage\n//\n//\tstore :=

- MetricScopeHWThread: Hardware thread (SMT) level metrics\n// - MetricScopeCore: CPU core level metrics\n// - MetricScopeSocket: CPU socket level metrics\n// - MetricScopeMemoryDomain: NUMA domain level metrics\n// - MetricScopeNode: Full node level metrics\n//\n// The client automatically handles scope transformations, aggregating finer-grained metrics\n// to coarser scopes when needed (e.g., aggregating core metrics to socket level).\n//\n// # Error Handling\n//\n// The client supports partial errors - if some queries fail, it returns both the successful\n// data and an error listing the failed queries. This allows processing partial results\n// when some nodes or metrics are temporarily unavailable.\n//\n// # API Versioning\n//\n// The client uses cc-metric-store API v2, which includes support for:\n// - Data resampling for bandwidth optimization\n// - Multi-scope queries in a single request\n// - Aggregation across hardware topology levels\npackage metricstoreclient\n\nimport

cc-metric-store is a high-performance time series database optimized for HPC metric data.\n// This client handles HTTP communication, query construction, scope transformations, and data retrieval\n// for job and node metrics across different metric scopes (node, socket, core, hwthread, accelerator).\n//\n// # Architecture\n//\n// The package is split into two main components:\n// - Client Operations (cc-metric-store.go): HTTP client, request handling, data loading methods\n// - Query Building (cc-metric-store-queries.go): Query construction and scope transformation logic\n//\n// # Basic Usage\n//\n//\tstore := NewCCMetricStore(\"http://localhost:8080\", \"jwt-token\")\n//\n//\t// Load job data\n//\tjobData, err := store.LoadData(job, metrics, scopes, ctx, resolution)\n//\tif err != nil {\n//\t log.Fatal(err)\n//\t}\n//\n// # Metric Scopes\n//\n// The client supports hierarchical metric scopes that map to HPC hardware topology:\n// - MetricScopeAccelerator: GPU/accelerator level metrics\n// - MetricScopeHWThread: Hardware thread (SMT) level metrics\n// - MetricScopeCore: CPU core level metrics\n// - MetricScopeSocket: CPU socket level metrics\n// - MetricScopeMemoryDomain: NUMA domain level metrics\n// - MetricScopeNode: Full node level metrics\n//\n// The client automatically handles scope transformations, aggregating finer-grained metrics\n// to coarser scopes when needed (e.g., aggregating core metrics to socket level).\n//\n// # Error Handling\n//\n// The client supports partial errors - if some queries fail, it returns both the successful\n// data and an error listing the failed queries. This allows processing partial results\n// when some nodes or metrics are temporarily unavailable.\n//\n// # API Versioning\n//\n// The client uses cc-metric-store API v2, which includes support for:\n// - Data resampling for bandwidth optimization\n// - Multi-scope queries in a single request\n// - Aggregation across hardware topology levels\npackage metricstoreclient\n\nimport

database.\n//\n// The cc-metric-store is a high-performance time series database optimized for HPC metric data.\n// This client handles HTTP communication, query construction, scope transformations, and data retrieval\n// for job and node metrics across different metric scopes (node, socket, core, hwthread, accelerator).\n//\n// # Architecture\n//\n// The package is split into two main components:\n// - Client Operations (cc-metric-store.go): HTTP client, request handling, data loading methods\n// - Query Building (cc-metric-store-queries.go): Query construction and scope transformation logic\n//\n// # Basic Usage\n//\n//\tstore := NewCCMetricStore(\"http://localhost:8080\", \"jwt-token\")\n//\n//\t// Load job data\n//\tjobData, err := store.LoadData(job, metrics,

MetricScopeAccelerator: GPU/accelerator level metrics\n// - MetricScopeHWThread: Hardware thread (SMT) level metrics\n// - MetricScopeCore: CPU core level metrics\n// - MetricScopeSocket: CPU socket level metrics\n// - MetricScopeMemoryDomain: NUMA domain level metrics\n// - MetricScopeNode: Full node level metrics\n//\n// The client automatically handles scope transformations, aggregating finer-grained metrics\n// to coarser scopes when needed (e.g., aggregating core metrics to socket level).\n//\n// # Error Handling\n//\n// The client supports partial errors - if some queries fail, it returns both the successful\n// data and an error listing the failed queries. This allows processing partial results\n// when some nodes or metrics are temporarily unavailable.\n//\n// # API Versioning\n//\n// The client uses cc-metric-store API v2, which includes support for:\n// - Data resampling for bandwidth optimization\n// - Multi-scope queries in a single request\n// - Aggregation across hardware topology levels\npackage metricstoreclient\n\nimport

cc-metric-store is a high-performance time series database optimized for HPC metric data.\n// This client handles HTTP communication, query construction, scope transformations, and data retrieval\n// for job and node metrics across different metric scopes (node, socket, core, hwthread, accelerator).\n//\n// # Architecture\n//\n// The package is split into two main components:\n// - Client Operations (cc-metric-store.go): HTTP client, request handling, data loading methods\n// - Query Building (cc-metric-store-queries.go): Query construction and scope transformation logic\n//\n// # Basic Usage\n//\n//\tstore := NewCCMetricStore(\"http://localhost:8080\", \"jwt-token\")\n//\n//\t// Load job data\n//\tjobData, err := store.LoadData(job, metrics, scopes, ctx, resolution)\n//\tif

level metrics\n// - MetricScopeHWThread: Hardware thread (SMT) level metrics\n// - MetricScopeCore: CPU core level metrics\n// - MetricScopeSocket: CPU socket level metrics\n// - MetricScopeMemoryDomain: NUMA domain level metrics\n// - MetricScopeNode: Full node level metrics\n//\n// The client automatically handles scope transformations, aggregating finer-grained metrics\n// to coarser scopes when needed (e.g., aggregating core metrics to socket level).\n//\n// # Error Handling\n//\n// The client supports partial errors - if some queries fail, it returns both the successful\n// data and an error listing the failed queries. This allows processing partial results\n// when some nodes or metrics are temporarily unavailable.\n//\n// # API Versioning\n//\n// The client uses cc-metric-store API v2, which includes support for:\n// - Data resampling for bandwidth optimization\n// - Multi-scope queries in a single request\n// - Aggregation across hardware topology levels\npackage metricstoreclient\n\nimport

package) scope\n// - MemoryDomain (NUMA domain) scope\n// - Node (full system) scope\n//\n// Transformations follow these rules:\n// - Same scope: Return data as-is (e.g., Core → Core)\n// - Coarser scope: Aggregate data (e.g., Core → Socket with Aggregate=true)\n// - Finer scope: Error - cannot increase granularity\n//\n// # Query Building\n//\n// buildQueries and buildNodeQueries are the main entry points, handling job-specific\n// and node-specific query construction respectively.

handles the complex mapping between requested metric scopes and native hardware topology,\n// automatically aggregating or filtering metrics as needed.\n//\n// # Scope Transformations\n//\n// The buildScopeQueries function implements the core scope transformation algorithm.\n// It handles 25+ different transformation cases, mapping between:\n// - Accelerator (GPU) scope\n// - HWThread (hardware thread/SMT) scope\n// - Core (CPU core) scope\n// - Socket (CPU package) scope\n// - MemoryDomain (NUMA domain) scope\n// - Node (full system) scope\n//\n// Transformations follow these rules:\n// - Same scope: Return data as-is (e.g., Core → Core)\n// - Coarser scope: Aggregate data (e.g., Core → Socket with Aggregate=true)\n// - Finer scope: Error - cannot increase granularity\n//\n// # Query Building\n//\n// buildQueries and buildNodeQueries are the main entry points, handling job-specific\n// and node-specific query construction respectively. They:\n// - Validate metric configurations\n// - Handle subcluster-specific metric filtering\n// - Detect and skip duplicate scope requests\n// - Call buildScopeQueries for each metric/scope/host

the following plan:\n\n# Plan: Trim Float Precision in JobClass Hint Messages\n\n## Context\nThe `JobClassTagger` generates hint messages via Go `text/template` rendering. Template variables like `{{.cpu_load.avg}}`, `{{.mem_bw_pct}}`, `{{.memory_usage_pct}}` are float64 values that render with full precision (e.g., `12.345678901234`), making messages hard to read. We need to automatically round floats to a reasonable precision before template rendering.\n\n## Approach\nAdd a helper function that recursively walks the env map and rounds all `float64` values to 2 decimal places. Create a rounded copy of the env for template execution only — rule evaluation continues to use full-precision values.\n\n## File to Modify\n- `internal/tagger/classifyJob.go`\n\n## Changes\n\n### 1. Add a `roundEnv` helper function\nRecursively walks a `map[string]any`, and for any `float64` value, rounds it to 2 decimal places. For nested `map[string]any` or `map[string]float64` values, recurse. Returns a new map (does not mutate the original).\n\n```go\nfunc roundEnv(env map[string]any) map[string]any {\n rounded := make(map[string]any, len(env))\n for k, v := range env {\n switch val := v.(type) {\n case float64:\n rounded[k] = math.Round(val*100) / 100\n case map[string]any:\n rounded[k] = roundEnv(val)\n case map[string]float64:\n rm := make(map[string]float64, len(val))\n for mk, mv := range val {\n rm[mk] = math.Round(mv*100) / 100\n }\n rounded[k] = rm\n default:\n rounded[k] = v\n }\n }\n return rounded\n}\n```\n\n### 2. Use rounded env for template execution in `Match()`\nAt line ~411, before `ri.hint.Execute(&msg, env)`, pass `roundEnv(env)` instead:\n\n```go\nif err := ri.hint.Execute(&msg, roundEnv(env)); err != nil {\n```\n\n### 3. Add `\"math\"` to imports\n\n## Verification\n- Run `go build ./...` to verify compilation\n- Run `go test ./internal/tagger/...` to verify existing tests pass\n- The test at line 88 uses `\"hint\": \"High FLOPS: {{.avg_flops}}\"` with a computed variable — this will exercise the rounding path\n\n\nIf you need specific details from before exiting plan mode (like exact code snippets, error messages, or content you generated), read the full transcript at: /Users/jan/.claude/projects/-Users-jan-prg-ClusterCockpit-cc-backend/71261f70-ba9c-4de4-9871-5921e6a371a1.jsonl"},"uuid":"84d926c5-84cd-4199-a1cb-52b035dcf5cf","timestamp":"2026-03-10T05:00:09.373Z","planContent":"# Plan: Trim Float Precision in JobClass Hint Messages\n\n## Context\nThe `JobClassTagger` generates hint messages via Go `text/template` rendering.

(hpc_user, job_state)\n8. `job_list_users_start` - (start_time, hpc_user, job_state)\n\n#### **Comprehensive Indexes Added in Migration 08 (08_add-footprint.up.sql):**\nThe migration dropped old indexes and created a much more extensive set of 80+ indexes organized by filter type:\n\n**Cluster Filter:**\n- `jobs_cluster` - (cluster)\n- `jobs_cluster_user` - (cluster, hpc_user)\n- `jobs_cluster_project` - (cluster, project)\n- `jobs_cluster_subcluster` - (cluster, subcluster)\n\n**Cluster Filter with Sorting:**\n- `jobs_cluster_starttime` -

(cluster, job_state, start_time, duration)\n\n---\n\n### **Direct Answer to Your Questions:**\n\n1. **Is there an index on `job_state`?** \n - **YES** - Multiple indexes include `job_state`:\n - `jobs_jobstate` -

**YES** - `jobs_jobstate_starttime` - (job_state, start_time) - explicitly created for this combination\n\n---\n\n### **Node State Indexes (Migration 10):**\n- `nodes_cluster` - (cluster)\n- `nodes_cluster_subcluster` -

(tag_id) on jobtag table\n\n---\n\n## `rows.Close()` Analysis\n\nI reviewed all `.Query()` calls in the repository files. Here are my findings:\n\n### **All `Query()` calls have proper `defer rows.Close()`:**\n\n**Files checked:**\n- `internal/repository/job.go` - All 8 Query() calls have defer rows.Close()\n- `internal/repository/jobFind.go` - All 4 Query() calls have defer rows.Close()\n- `internal/repository/jobQuery.go` - Query() call has defer rows.Close()\n- `internal/repository/jobCreate.go` - Query() call has defer rows.Close()\n- `internal/repository/tags.go` - All 4 Query() calls have defer rows.Close()\n- `internal/repository/node.go` - All Query() calls have defer rows.Close()\n- `internal/repository/stats.go` - All Query() calls have defer rows.Close()\n\n**Note:** In `job.go` (line 603-610), there's a conditional defer in `FindColumnValues()`:\n```go\nrows, err := ...Query()\nif err != nil && err != sql.ErrNoRows {\n return emptyResult, fmt.Errorf(...)\n} else if err == nil {\n defer rows.Close() // Conditional defer - only called when err is nil\n // process rows\n}\n```\nThis is safe because `defer rows.Close()` is only executed when the error is nil (i.e., when rows is valid).\n\n### **FindJobIdsByTag Function:**\nLocated at `/Users/jan/prg/CC/cc-backend/internal/repository/job.go:747`\n\nThe function properly uses:\n```go\nrows, err := query.RunWith(r.stmtCache).Query()\nif err != nil {\n return nil, fmt.Errorf(...)\n}\ndefer rows.Close() // ✓ Properly deferred\n```\n\n---\n\n## Summary\n\n**All database resources are properly managed.** No missing `rows.Close()` calls were found. The codebase follows Go best practices by using `defer` statements to ensure row sets are closed even if errors occur during iteration.\n\nThe database schema includes extensive indexes optimized for filtering and sorting by cluster, job_state, start_time, and user—including the specific composite index `(job_state, start_time)` for efficient queries combining these conditions."},{"type":"text","text":"agentId: a7b417d75bd07c822 (for resuming to continue this agent's work if needed)\ntotal_tokens: 60120\ntool_uses: 26\nduration_ms: 112747"}]}]},"uuid":"f1fecc74-12f7-481d-b004-ff9199a1ca15","timestamp":"2026-03-11T04:15:42.843Z","toolUseResult":{"status":"completed","prompt":"In /Users/jan/prg/CC/cc-backend, find all database index definitions.

Here's a summary of findings and fixes:\n\n---\n\n## Findings\n\n### Bug 1: Missing `defer rows.Close()` in `user.go:GetLdapUsernames()` (line 100)\n**Fixed.** Every call leaked a database connection and its buffers.\n\n### Bug 2: SQLite never runs `ANALYZE` — wrong index selection\n**Fixed.** Added `ANALYZE` to `setupSqlite()` in `dbConnection.go`.\n\nWithout statistics in `sqlite_stat1`, SQLite's query planner **guessed** and chose `jobs_jobstate_energy` (a terrible index for this query) instead of scanning `jobs_starttime` in reverse. The result:\n\n| | Before ANALYZE | After ANALYZE |\n|---|---|---|\n| Index used | `jobs_jobstate_energy` | `jobs_starttime` |\n| Sort | **TEMP B-TREE** (materializes ALL rows) | None (index order) |\n| Memory | Proportional to total matching rows | Constant |\n| I/O | Full scan of all matching rows | Stops at OFFSET+LIMIT |\n\n### Bug 3: `IN` clause + `ORDER BY` is fundamentally incompatible with composite indexes\n\nEven with the \"correct\" index `(job_state, start_time)`, SQLite **cannot** merge-sort across 3 separate index range scans for `IN ('completed','running','failed')`. It always falls back to a temp B-tree sort. The only efficient plan is to use the standalone `jobs_starttime` index — which SQLite does automatically **after ANALYZE** because it realizes the 3 states cover virtually all rows, making the WHERE clause nearly a no-op.\n\n### Observation: 79 indexes on the `job` table\nThis is excessive and actively harmful — it confuses the query planner (especially without ANALYZE) and slows writes. The `jobs_jobstate_starttime` index from migration 08 is also missing from the actual DB (only the 3-column `jobs_jobstate_starttime_duration` exists).

The hardcoded defaults (200MB cache per connection, 1GB soft heap limit) are conservative. On the production server with 512GB RAM, these could be tuned higher for better query performance. Additionally, `RepositoryConfig` and `SetConfig()` exist but are **never wired up** — there's currently no way to override any repository defaults from config.json.\n\n## Current State (already implemented on this branch)\n\n- `_cache_size = -200000` (200MB per connection, hardcoded) — **too low for 80GB DB, will be made configurable**\n- `soft_heap_limit = 1073741824` (1GB process-wide, hardcoded) — **too low, will be made configurable**\n- `ConnectionMaxIdleTime = 10 * time.Minute` (hardcoded default)\n- `MaxOpenConnections = 4` (hardcoded default)\n- Context propagation to all query call sites (already done)\n\n## Problem\n\n`repository.SetConfig()` exists but is never called from `main.go`. The `initDatabase()` function (line 110) just calls `repository.Connect(config.Keys.DB)` directly. There's no `\"db-config\"` section in `ProgramConfig` or the JSON schema.\n\n## Proposed Changes\n\n### 1. Add SQLite memory fields to `RepositoryConfig`\n\n**File:** `internal/repository/config.go`\n\nAdd two new fields with sensible defaults:\n\n```go\ntype RepositoryConfig struct {\n // ... existing fields ...\n\n // DbCacheSizeMB is the SQLite page cache size per connection in MB.\n // Uses negative PRAGMA cache_size notation (KiB). With MaxOpenConnections=4\n // and DbCacheSizeMB=200, total page cache is up to 800MB.\n // Default: 200 (MB)\n DbCacheSizeMB int\n\n // DbSoftHeapLimitMB is the process-wide SQLite soft heap limit in MB.\n // SQLite will try to release cache pages to stay under this limit.\n // It's a soft limit — queries won't fail, but cache eviction becomes more aggressive.\n // Default: 1024 (1GB)\n DbSoftHeapLimitMB int\n}\n```\n\nUpdate `DefaultConfig()`:\n```go\nDbCacheSizeMB: 2048, // 2GB per connection\nDbSoftHeapLimitMB: 16384, // 16GB process-wide\n```\n\n**Rationale for defaults:** With an 80GB production database on a 512GB server, we want the cache to hold a significant portion of the DB. At 4 connections × 2GB = 8GB default page cache, plus 16GB soft heap limit. The previous 200MB/1GB hardcoded values were too conservative and would hurt query performance by forcing excessive cache eviction. These defaults use ~5% of a 512GB server — still safe for smaller machines, while enabling good performance on production.\n\n### 2. Use config values in `Connect()` and `setupSqlite()`\n\n**File:** `internal/repository/dbConnection.go`\n\nIn `Connect()`, replace the hardcoded cache_size:\n```go\ncacheSizeKiB := repoConfig.DbCacheSizeMB * 1024 // Convert MB to KiB\nconnectionURLParams.Add(\"_cache_size\", fmt.Sprintf(\"-%d\", cacheSizeKiB))\n```\n\nChange `setupSqlite()` to accept the config and use it for soft_heap_limit:\n```go\nfunc setupSqlite(db *sql.DB, cfg *RepositoryConfig) error {\n pragmas := []string{\n \"temp_store = memory\",\n fmt.Sprintf(\"soft_heap_limit = %d\", cfg.DbSoftHeapLimitMB*1024*1024),\n }\n // ...\n}\n```\n\nUpdate the call site in `Connect()`:\n```go\nerr = setupSqlite(dbHandle.DB, &opts) // was: setupSqlite(dbHandle.DB)\n```\n\n### 3. Add `\"db-config\"` section to `ProgramConfig` and JSON schema\n\n**File:** `internal/config/config.go`\n\nAdd a new struct and field to `ProgramConfig`:\n\n```go\ntype DbConfig struct {\n CacheSizeMB int `json:\"cache-size-mb\"`\n SoftHeapLimitMB int `json:\"soft-heap-limit-mb\"`\n MaxOpenConnections int `json:\"max-open-connections\"`\n MaxIdleConnections int `json:\"max-idle-connections\"`\n ConnectionMaxIdleTimeMins int `json:\"max-idle-time-minutes\"`\n}\n\ntype ProgramConfig struct {\n // ... existing fields ...\n DbConfig *DbConfig `json:\"db-config\"`\n}\n```\n\n**File:** `internal/config/schema.go`\n\nAdd the schema section for validation.\n\n### 4. Wire `SetConfig()` in `initDatabase()`\n\n**File:** `cmd/cc-backend/main.go`\n\n```go\nfunc initDatabase() error {\n if config.Keys.DbConfig != nil {\n cfg := repository.DefaultConfig()\n dc := config.Keys.DbConfig\n if dc.CacheSizeMB > 0 {\n cfg.DbCacheSizeMB = dc.CacheSizeMB\n }\n if dc.SoftHeapLimitMB > 0 {\n cfg.DbSoftHeapLimitMB = dc.SoftHeapLimitMB\n }\n if dc.MaxOpenConnections > 0 {\n cfg.MaxOpenConnections = dc.MaxOpenConnections\n }\n if dc.MaxIdleConnections > 0 {\n cfg.MaxIdleConnections = dc.MaxIdleConnections\n }\n if dc.ConnectionMaxIdleTimeMins > 0 {\n cfg.ConnectionMaxIdleTime = time.Duration(dc.ConnectionMaxIdleTimeMins) * time.Minute\n }\n repository.SetConfig(cfg)\n }\n repository.Connect(config.Keys.DB)\n return nil\n}\n```\n\n### 5. Log effective values on startup\n\n**File:** `internal/repository/dbConnection.go`\n\nAfter setting PRAGMAs, log the effective values so operators can verify:\n```go\ncclog.Infof(\"SQLite config: cache_size=%dMB/conn, soft_heap_limit=%dMB, max_conns=%d\",\n repoConfig.DbCacheSizeMB, repoConfig.DbSoftHeapLimitMB, repoConfig.MaxOpenConnections)\n```\n\n## Example config.json (for 512GB server with 80GB database)\n\n```json\n{\n \"main\": {\n \"db\": \"./var/job.db\",\n \"db-config\": {\n \"cache-size-mb\": 16384,\n \"soft-heap-limit-mb\": 131072,\n \"max-open-connections\": 8,\n \"max-idle-time-minutes\": 30\n }\n }\n}\n```\n\nThis would give: 8 connections × 16GB cache = 128GB max page cache, with a 128GB soft heap limit. The entire 80GB database can be cached in memory. On a 512GB server that's ~25% of RAM.\n\n**Sizing guidance (for documentation):**\n- `cache-size-mb`: Set to `DB_size / max-open-connections` to allow the entire DB to be cached. E.g., 80GB DB with 8 connections → 10GB per connection minimum.\n- `soft-heap-limit-mb`: Set to total desired SQLite memory budget. Should be ≥ `cache-size-mb × max-open-connections` to avoid cache thrashing.\n\n## Files to Modify\n\n| File | Changes |\n|------|---------|\n| `internal/repository/config.go` | Add `DbCacheSizeMB`, `DbSoftHeapLimitMB` fields + defaults |\n| `internal/repository/dbConnection.go` | Use config values instead of hardcoded; pass config to `setupSqlite`; add startup log |\n| `internal/config/config.go` | Add `DbConfig` struct and field to `ProgramConfig` |\n| `internal/config/schema.go` | Add `\"db-config\"` JSON schema section |\n| `cmd/cc-backend/main.go` | Wire `SetConfig()` in `initDatabase()` |\n\n## Verification\n\n1. `go build ./...` — compiles\n2. `go test ./internal/repository/... ./internal/config/...` — tests pass\n3. Without `db-config` in config.json: defaults apply (200MB cache, 1GB heap) — backwards compatible\n4.

Wire `SetConfig()` in `initDatabase()`\n\n**File:** `cmd/cc-backend/main.go`\n\n```go\nfunc initDatabase() error {\n if config.Keys.DbConfig != nil {\n cfg := repository.DefaultConfig()\n dc := config.Keys.DbConfig\n if dc.CacheSizeMB > 0 {\n cfg.DbCacheSizeMB = dc.CacheSizeMB\n }\n if dc.SoftHeapLimitMB > 0 {\n cfg.DbSoftHeapLimitMB = dc.SoftHeapLimitMB\n }\n if dc.MaxOpenConnections > 0 {\n cfg.MaxOpenConnections = dc.MaxOpenConnections\n }\n if dc.MaxIdleConnections > 0 {\n cfg.MaxIdleConnections = dc.MaxIdleConnections\n }\n if dc.ConnectionMaxIdleTimeMins > 0 {\n cfg.ConnectionMaxIdleTime = time.Duration(dc.ConnectionMaxIdleTimeMins) * time.Minute\n }\n repository.SetConfig(cfg)\n }\n repository.Connect(config.Keys.DB)\n return nil\n}\n```\n\n### 5.

Add SQLite memory fields to `RepositoryConfig` + +**File:** `internal/repository/config.go` + +Add two new fields with sensible defaults: + +```go +type RepositoryConfig struct { + // ... existing fields ... + + // DbCacheSizeMB is the SQLite page cache size per connection in MB. + // Uses negative PRAGMA cache_size notation (KiB). With MaxOpenConnections=4 + // and DbCacheSizeMB=200, total page cache is up to 800MB. + // Default: 200 (MB) + DbCacheSizeMB int + + // DbSoftHeapLimitMB is the process-wide SQLite soft heap limit in MB. + // SQLite will try to release cache pages to stay under this limit. + // It's a soft limit — queries won't fail, but cache eviction becomes more aggressive. + // Default: 1024 (1GB) + DbSoftHeapLimitMB int +} +``` + +Update `DefaultConfig()`: +```go +DbCacheSizeMB: 2048, // 2GB per connection +DbSoftHeapLimitMB: 16384, // 16GB process-wide +``` + +**Rationale for defaults:** With an 80GB production database on a 512GB server, we want the cache to hold a significant portion of the DB. At 4 connections × 2GB = 8GB default page cache, plus 16GB soft heap limit. The previous 200MB/1GB hardcoded values were too conservative and would hurt query performance by forcing excessive cache eviction. These defaults use ~5% of a 512GB server — still safe for smaller machines, while enabling good performance on production. + +### 2. Use config values in `Connect()` and `setupSqlite()` + +**File:** `internal/repository/dbConnection.go` + +In `Connect()`, replace the hardcoded cache_size: +```go +cacheSizeKiB := repoConfig.DbCacheSizeMB * 1024 // Convert MB to KiB +connectionURLParams.Add("_cache_size", fmt.Sprintf("-%d", cacheSizeKiB)) +``` + +Change `setupSqlite()` to accept the config and use it for soft_heap_limit: +```go +func setupSqlite(db *sql.DB, cfg *RepositoryConfig) error { + pragmas := []string{ + "temp_store = memory", + fmt.Sprintf("soft_heap_limit = %d", cfg.DbSoftHeapLimitMB*1024*1024), + } + // ... +} +``` + +Update the call site in `Connect()`: +```go +err = setupSqlite(dbHandle.DB, &opts) // was: setupSqlite(dbHandle.DB) +``` + +### 3.

Wire `SetConfig()` in `initDatabase()` + +**File:** `cmd/cc-backend/main.go` + +```go +func initDatabase() error { + if config.Keys.DbConfig != nil { + cfg := repository.DefaultConfig() + dc := config.Keys.DbConfig + if dc.CacheSizeMB > 0 { + cfg.DbCacheSizeMB = dc.CacheSizeMB + } + if dc.SoftHeapLimitMB > 0 { + cfg.DbSoftHeapLimitMB = dc.SoftHeapLimitMB + } + if dc.MaxOpenConnections > 0 { + cfg.MaxOpenConnections = dc.MaxOpenConnections + } + if dc.MaxIdleConnections > 0 { + cfg.MaxIdleConnections = dc.MaxIdleConnections + } + if dc.ConnectionMaxIdleTimeMins > 0 { + cfg.ConnectionMaxIdleTime = time.Duration(dc.ConnectionMaxIdleTimeMins) * time.Minute + } + repository.SetConfig(cfg) + } + repository.Connect(config.Keys.DB) + return nil +} +``` + +### 5.

The entire 80GB database can be cached in memory. On a 512GB server that's ~25% of RAM. + +**Sizing guidance (for documentation):** +- `cache-size-mb`: Set to `DB_size / max-open-connections` to allow the entire DB to be cached. E.g., 80GB DB with 8 connections → 10GB per connection minimum. +- `soft-heap-limit-mb`: Set to total desired SQLite memory budget.

The process stays bloated until restarted. This is caused by three compounding issues in the current SQLite configuration.\n\n## Root Cause Analysis\n\n### 1. `_cache_size=1000000000` is effectively unlimited (~4TB)\n\n**File:** `internal/repository/dbConnection.go:82`\n\n```go\nconnectionURLParams.Add(\"_cache_size\", \"1000000000\")\n```\n\nSQLite's `cache_size` PRAGMA interprets **positive values as page count** (default page size = 4KB). So 1,000,000,000 pages × 4KB = ~4TB. In practice, this means \"never evict cached pages.\" After a full-table scan of 20M rows, every page touched stays in SQLite's page cache. With 4 connections (`MaxOpenConns=4`), each can independently cache gigabytes.\n\nFor comparison, the SQLite archive backend in `pkg/archive/sqliteBackend.go` uses `PRAGMA cache_size=-64000` (64MB — negative = KiB).\n\n### 2. No query context/timeout — queries run indefinitely\n\n**File:** `internal/repository/jobQuery.go:87`\n\n```go\nrows, err := query.RunWith(r.stmtCache).Query() // No context!\n```\n\nThe `ctx` parameter is available but never passed to the database layer. Squirrel supports `.QueryContext(ctx)` but it's not used. If the HTTP request times out or the client disconnects, the query keeps running and scanning pages into cache.\n\n### 3. No SQLite memory limit — no `soft_heap_limit` or `shrink_memory`\n\nSQLite has built-in memory management PRAGMAs that are not configured:\n- **`soft_heap_limit`** — asks SQLite to keep heap usage below N bytes (best-effort, releases cache pages to stay under limit)\n- **`hard_heap_limit`** — hard cap, queries fail with SQLITE_NOMEM if exceeded\n- **`shrink_memory`** — immediately releases all unused memory back to the OS\n\nNone of these are set, so SQLite allocates freely and never releases.\n\n### 4. `temp_store = memory` amplifies the problem\n\n**File:** `internal/repository/dbConnection.go:41`\n\nTemporary B-tree sorts (exactly what happens during ORDER BY on a full-table scan) are stored in RAM. With 20M rows and no sort optimization, this can be gigabytes of temporary memory on top of the page cache.\n\n### 5. Connections live for 1 hour after use\n\n`ConnMaxIdleTime = 1 hour` means a connection that just did a massive full-table scan sits idle in the pool for up to an hour, holding all its cached pages.\n\n## Proposed Changes\n\n### Fix 1: Set reasonable `cache_size` (high impact, low risk)\n\n**File:** `internal/repository/dbConnection.go:82`\n\nChange from `1000000000` (1B pages ≈ 4TB) to `-200000` (200MB in KiB notation, per connection):\n\n```go\nconnectionURLParams.Add(\"_cache_size\", \"-200000\") // 200MB per connection\n```\n\nWith 4 max connections: 4 × 200MB = 800MB max page cache. This is generous enough for normal queries but prevents runaway memory after full-table scans.\n\n### Fix 2: Add `soft_heap_limit` (high impact, low risk)\n\n**File:** `internal/repository/dbConnection.go`, in `setupSqlite()`:\n\n```go\n\"soft_heap_limit = 1073741824\", // 1GB soft limit across all connections\n```\n\nThis is a **process-wide** limit (not per-connection). SQLite will try to release cache pages to stay under 1GB total. It's a soft limit — it won't abort queries, just evicts cache more aggressively.\n\n### Fix 3: Pass context to database queries (medium impact, medium effort)\n\nChange `.Query()` to `.QueryContext(ctx)`, `.QueryRow()` to `.QueryRowContext(ctx)`, and `.Scan()` to `.ScanContext(ctx)` for all query methods that already receive a `ctx` parameter. This allows HTTP request cancellation to stop the SQLite query.\n\n**Note:** The `stmtCache` from squirrel supports `QueryContext`/`QueryRowContext`. Only methods that already have `ctx` are changed — no signature changes needed.\n\n**Call sites to update** (methods that have `ctx` and call `.Query()`/`.QueryRow()`/`.Scan()`):\n\n| File | Method | Line | Change |\n|------|--------|------|--------|\n| `jobQuery.go` | `QueryJobs` | 87 | `.Query()` → `.QueryContext(ctx)` |\n| `jobQuery.go` | `CountJobs` | 129 | `.Scan()` → `.ScanContext(ctx)` |\n| `stats.go` | `JobsStatsGrouped` | 233 | `.Query()` → `.QueryContext(ctx)` |\n| `stats.go` | `JobsStats` | 358 | `.QueryRow()` → `.QueryRowContext(ctx)` |\n| `stats.go` | `JobCountGrouped` | 443 | `.Query()` → `.QueryContext(ctx)` |\n| `stats.go` | `AddJobCountGrouped` | 504 | `.Query()` → `.QueryContext(ctx)` |\n| `stats.go` | `AddJobCount` | 569 | `.Scan()` → `.ScanContext(ctx)` |\n| `stats.go` | `jobsStatisticsHistogram` | 758 | `.Query()` → `.QueryContext(ctx)` |\n| `stats.go` | `jobsDurationStatisticsHistogram` | 832 | `.Query()` → `.QueryContext(ctx)` |\n| `stats.go` | `jobsMetricStatisticsHistogram` | 962 | `.Query()` → `.QueryContext(ctx)` |\n| `jobFind.go` | `FindByID` | 174 | `.QueryRow()` → `.QueryRowContext(ctx)` |\n| `jobFind.go` | `FindByJobID` | 220 | `.QueryRow()` → `.QueryRowContext(ctx)` |\n| `job.go` | `CountGroupedJobs` | 410 | `.Scan()` → `.ScanContext(ctx)` (needs ctx added to signature) |\n| `job.go` | `GetJobList` | 751 | `.Query()` → `.QueryContext(ctx)` (needs ctx added to signature) |\n\nMethods without `ctx` in their signature (e.g., `GetJobList`, `CountGroupedJobs`) can either have `ctx` added or be left for a follow-up. The priority is the methods already accepting `ctx`.\n\n### Fix 4: Reduce `ConnMaxIdleTime`\n\n**File:** `internal/repository/config.go`\n\nReduce `ConnectionMaxIdleTime` from 1 hour to 10 minutes. Idle connections with cached pages are released sooner.\n\n## Scope — All Four Fixes\n\nAll fixes are complementary, independent, and low-risk. No disadvantages to applying all together.\n\n## Files to Modify\n\n- `internal/repository/dbConnection.go` — cache_size, soft_heap_limit (Fixes 1 & 2)\n- `internal/repository/jobQuery.go` — QueryContext (Fix 3)\n- `internal/repository/job.go` — QueryContext for other query methods (Fix 3)\n- `internal/repository/stats.go` — QueryContext for stats queries (Fix 3)\n- `internal/repository/config.go` — ConnMaxIdleTime (Fix 4, optional)\n\n## Verification\n\n1. `go build ./...` — compiles\n2. `go test ./internal/repository/...` — tests pass\n3.

With 4 connections (`MaxOpenConns=4`), each can independently cache gigabytes.\n\nFor comparison, the SQLite archive backend in `pkg/archive/sqliteBackend.go` uses `PRAGMA cache_size=-64000` (64MB — negative = KiB).\n\n### 2. No query context/timeout — queries run indefinitely\n\n**File:** `internal/repository/jobQuery.go:87`\n\n```go\nrows, err := query.RunWith(r.stmtCache).Query() // No context!\n```\n\nThe `ctx` parameter is available but never passed to the database layer. Squirrel supports `.QueryContext(ctx)` but it's not used. If the HTTP request times out or the client disconnects, the query keeps running and scanning pages into cache.\n\n### 3. No SQLite memory limit — no `soft_heap_limit` or `shrink_memory`\n\nSQLite has built-in memory management PRAGMAs that are not configured:\n- **`soft_heap_limit`** — asks SQLite to keep heap usage below N bytes (best-effort, releases cache pages to stay under limit)\n- **`hard_heap_limit`** — hard cap, queries fail with SQLITE_NOMEM if exceeded\n- **`shrink_memory`** — immediately releases all unused memory back to the OS\n\nNone of these are set, so SQLite allocates freely and never releases.\n\n### 4. `temp_store = memory` amplifies the problem\n\n**File:** `internal/repository/dbConnection.go:41`\n\nTemporary B-tree sorts (exactly what happens during ORDER BY on a full-table scan) are stored in RAM. With 20M rows and no sort optimization, this can be gigabytes of temporary memory on top of the page cache.\n\n### 5. Connections live for 1 hour after use\n\n`ConnMaxIdleTime = 1 hour` means a connection that just did a massive full-table scan sits idle in the pool for up to an hour, holding all its cached pages.\n\n## Proposed Changes\n\n### Fix 1: Set reasonable `cache_size` (high impact, low risk)\n\n**File:** `internal/repository/dbConnection.go:82`\n\nChange from `1000000000` (1B pages ≈ 4TB) to `-200000` (200MB in KiB notation, per connection):\n\n```go\nconnectionURLParams.Add(\"_cache_size\", \"-200000\") // 200MB per connection\n```\n\nWith 4 max connections: 4 × 200MB = 800MB max page cache. This is generous enough for normal queries but prevents runaway memory after full-table scans.\n\n### Fix 2: Add `soft_heap_limit` (high impact, low risk)\n\n**File:** `internal/repository/dbConnection.go`, in `setupSqlite()`:\n\n```go\n\"soft_heap_limit = 1073741824\", // 1GB soft limit across all connections\n```\n\nThis is a **process-wide** limit (not per-connection). SQLite will try to release cache pages to stay under 1GB total. It's a soft limit — it won't abort queries, just evicts cache more aggressively.\n\n### Fix 3: Pass context to database queries (medium impact, medium effort)\n\nChange `.Query()` to `.QueryContext(ctx)`, `.QueryRow()` to `.QueryRowContext(ctx)`, and `.Scan()` to `.ScanContext(ctx)` for all query methods that already receive a `ctx` parameter. This allows HTTP request cancellation to stop the SQLite query.\n\n**Note:** The `stmtCache` from squirrel supports `QueryContext`/`QueryRowContext`. Only methods that already have `ctx` are changed — no signature changes needed.\n\n**Call sites to update** (methods that have `ctx` and call `.Query()`/`.QueryRow()`/`.Scan()`):\n\n| File | Method | Line | Change |\n|------|--------|------|--------|\n| `jobQuery.go` | `QueryJobs` | 87 | `.Query()` → `.QueryContext(ctx)` |\n| `jobQuery.go` | `CountJobs` | 129 | `.Scan()` → `.ScanContext(ctx)` |\n| `stats.go` | `JobsStatsGrouped` | 233 | `.Query()` → `.QueryContext(ctx)` |\n| `stats.go` | `JobsStats` | 358 | `.QueryRow()` → `.QueryRowContext(ctx)` |\n| `stats.go` | `JobCountGrouped` | 443 | `.Query()` → `.QueryContext(ctx)` |\n| `stats.go` | `AddJobCountGrouped` | 504 | `.Query()` → `.QueryContext(ctx)` |\n| `stats.go` | `AddJobCount` | 569 | `.Scan()` → `.ScanContext(ctx)` |\n| `stats.go` | `jobsStatisticsHistogram` | 758 | `.Query()` → `.QueryContext(ctx)` |\n| `stats.go` | `jobsDurationStatisticsHistogram` | 832 | `.Query()` → `.QueryContext(ctx)` |\n| `stats.go` | `jobsMetricStatisticsHistogram` | 962 | `.Query()` → `.QueryContext(ctx)` |\n| `jobFind.go` | `FindByID` | 174 | `.QueryRow()` → `.QueryRowContext(ctx)` |\n| `jobFind.go` | `FindByJobID` | 220 | `.QueryRow()` → `.QueryRowContext(ctx)` |\n| `job.go` | `CountGroupedJobs` | 410 | `.Scan()` → `.ScanContext(ctx)` (needs ctx added to signature) |\n| `job.go` | `GetJobList` | 751 | `.Query()` → `.QueryContext(ctx)` (needs ctx added to signature) |\n\nMethods without `ctx` in their signature (e.g., `GetJobList`, `CountGroupedJobs`) can either have `ctx` added or be left for a follow-up. The priority is the methods already accepting `ctx`.\n\n### Fix 4: Reduce `ConnMaxIdleTime`\n\n**File:** `internal/repository/config.go`\n\nReduce `ConnectionMaxIdleTime` from 1 hour to 10 minutes. Idle connections with cached pages are released sooner.\n\n## Scope — All Four Fixes\n\nAll fixes are complementary, independent, and low-risk. No disadvantages to applying all together.\n\n## Files to Modify\n\n- `internal/repository/dbConnection.go` — cache_size, soft_heap_limit (Fixes 1 & 2)\n- `internal/repository/jobQuery.go` — QueryContext (Fix 3)\n- `internal/repository/job.go` — QueryContext for other query methods (Fix 3)\n- `internal/repository/stats.go` — QueryContext for stats queries (Fix 3)\n- `internal/repository/config.go` — ConnMaxIdleTime (Fix 4, optional)\n\n## Verification\n\n1. `go build ./...` — compiles\n2. `go test ./internal/repository/...` — tests pass\n3. Monitor RSS memory before/after on production:\n - Trigger a heavy query, observe memory spike\n - Verify memory drops back down within seconds (not hours)\n4. `PRAGMA cache_size;` in sqlite3 CLI on running DB — should show `-200000`\n5. `PRAGMA soft_heap_limit;` — should show `1073741824`\n"} +{"parentUuid":"4a724aea-ee79-41a7-929d-fa3f906ac8b9","isSidechain":false,"userType":"external","cwd":"/Users/jan/prg/CC/cc-backend","sessionId":"520afa6a-6a70-437b-96c1-35c40ed3ec48","version":"2.1.72","gitBranch":"optimize-db-indices","slug":"refactored-wishing-journal","message":{"model":"claude-opus-4-6","id":"msg_01PRqzmUw2xM1Ra5kk6M4d2E","type":"message","role":"assistant","content":[{"type":"thinking","thinking":"","signature":"EoICCkYICxgCKkBHgN2UeZvCwmGQLUT1lci1RmXS8GvFO6QBbR0lTwucDfKJuxDQuAs0c5iaIbFwKKwuw2UPqq/nDgNaNrcpYcpHEgw8CBV0zTgUoz64jMAaDBbkztA7pDku4Xic7iIwL1kuLcdfEMbYki/6ssZFVP2WAMSg9KVIJVChV0ubqHzjC2BKqhlI126oGnx1XnCJKmqjQ4iBv8+LhF4RfOZpfVfzeg+D8aGuPl79aJ7dWgzL9PkGD+CVqmpYcM0s+dsh8azEbyNAsDJ05jTyW7KxYngoq7k36ohFz/UoF57opUDcMXPfZlRbKYkMLZY/cpdAWIzh7jmagVNfqfDuGAE="}],"stop_reason":null,"stop_sequence":null,"usage":{"input_tokens":3,"cache_creation_input_tokens":8833,"cache_read_input_tokens":8781,"cache_creation":{"ephemeral_5m_input_tokens":0,"ephemeral_1h_input_tokens":8833},"output_tokens":9,"service_tier":"standard","inference_geo":"not_available"}},"requestId":"req_011CYvhsLHSzP7FPK81HS9pG","type":"assistant","uuid":"57154933-cba3-43d3-b80e-2848f9685fe7","timestamp":"2026-03-11T05:01:39.634Z"} +{"parentUuid":"57154933-cba3-43d3-b80e-2848f9685fe7","isSidechain":false,"userType":"external","cwd":"/Users/jan/prg/CC/cc-backend","sessionId":"520afa6a-6a70-437b-96c1-35c40ed3ec48","version":"2.1.72","gitBranch":"optimize-db-indices","slug":"refactored-wishing-journal","message":{"model":"claude-opus-4-6","id":"msg_01PRqzmUw2xM1Ra5kk6M4d2E","type":"message","role":"assistant","content":[{"type":"tool_use","id":"toolu_01BVouxo65S9Ysq9RgPFEKPu","name":"Read","input":{"file_path":"/Users/jan/prg/CC/cc-backend/internal/repository/dbConnection.go"},"caller":{"type":"direct"}}],"stop_reason":null,"stop_sequence":null,"usage":{"input_tokens":3,"cache_creation_input_tokens":8833,"cache_read_input_tokens":8781,"cache_creation":{"ephemeral_5m_input_tokens":0,"ephemeral_1h_input_tokens":8833},"output_tokens":9,"service_tier":"standard","inference_geo":"not_available"}},"requestId":"req_011CYvhsLHSzP7FPK81HS9pG","type":"assistant","uuid":"45a469f0-4916-43d0-8046-d2d200e01fbc","timestamp":"2026-03-11T05:01:40.051Z"} +{"parentUuid":"45a469f0-4916-43d0-8046-d2d200e01fbc","isSidechain":false,"userType":"external","cwd":"/Users/jan/prg/CC/cc-backend","sessionId":"520afa6a-6a70-437b-96c1-35c40ed3ec48","version":"2.1.72","gitBranch":"optimize-db-indices","slug":"refactored-wishing-journal","type":"progress","data":{"type":"hook_progress","hookEvent":"PostToolUse","hookName":"PostToolUse:Read","command":"callback"},"parentToolUseID":"toolu_01BVouxo65S9Ysq9RgPFEKPu","toolUseID":"toolu_01BVouxo65S9Ysq9RgPFEKPu","timestamp":"2026-03-11T05:01:40.077Z","uuid":"96e3441e-29d9-4b04-bbe7-65ce3b14da71"} +{"parentUuid":"45a469f0-4916-43d0-8046-d2d200e01fbc","isSidechain":false,"userType":"external","cwd":"/Users/jan/prg/CC/cc-backend","sessionId":"520afa6a-6a70-437b-96c1-35c40ed3ec48","version":"2.1.72","gitBranch":"optimize-db-indices","slug":"refactored-wishing-journal","type":"user","message":{"role":"user","content":[{"tool_use_id":"toolu_01BVouxo65S9Ysq9RgPFEKPu","type":"tool_result","content":" 1→// Copyright (C) NHR@FAU, University Erlangen-Nuremberg.\n 2→// All rights reserved.

tests pass. Here's a summary of all changes:\n\n### Fix 1: Cache size (`dbConnection.go:82`)\nChanged `_cache_size` from `1000000000` (~4TB) to `-200000` (200MB per connection in KiB notation).

Monitor RSS memory before/after on production:\n - Trigger a heavy query, observe memory spike\n - Verify memory drops back down within seconds (not hours)\n4. `PRAGMA cache_size;` in sqlite3 CLI on running DB — should show `-200000`\n5. `PRAGMA soft_heap_limit;` — should show `1073741824`\n","numLines":128,"startLine":1,"totalLines":128}},"sourceToolAssistantUUID":"0207d447-0f95-4741-9e3f-357c5927b88d"} +{"parentUuid":"0c26389c-193b-4713-8ceb-5410d277773c","isSidechain":false,"userType":"external","cwd":"/Users/jan/prg/CC/cc-backend","sessionId":"520afa6a-6a70-437b-96c1-35c40ed3ec48","version":"2.1.72","gitBranch":"optimize-db-indices","slug":"refactored-wishing-journal","message":{"model":"claude-opus-4-6","id":"msg_01Ty3nZThiDynrRqBk1xwS31","type":"message","role":"assistant","content":[{"type":"thinking","thinking":"","signature":"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"}],"stop_reason":null,"stop_sequence":null,"usage":{"input_tokens":1,"cache_creation_input_tokens":2547,"cache_read_input_tokens":59738,"cache_creation":{"ephemeral_5m_input_tokens":2547,"ephemeral_1h_input_tokens":0},"output_tokens":8,"service_tier":"standard","inference_geo":"not_available"}},"requestId":"req_011CYviBCVPgMZuoywhNg8Vz","type":"assistant","uuid":"9a9b97a6-3d5d-416d-8e46-c998c035966c","timestamp":"2026-03-11T05:05:43.076Z"} +{"parentUuid":"9a9b97a6-3d5d-416d-8e46-c998c035966c","isSidechain":false,"userType":"external","cwd":"/Users/jan/prg/CC/cc-backend","sessionId":"520afa6a-6a70-437b-96c1-35c40ed3ec48","version":"2.1.72","gitBranch":"optimize-db-indices","slug":"refactored-wishing-journal","message":{"model":"claude-opus-4-6","id":"msg_01Ty3nZThiDynrRqBk1xwS31","type":"message","role":"assistant","content":[{"type":"text","text":"Good question.

Currently, the system uses only default values from `DefaultConfig()`.\n\n### 2. **RepositoryConfig Structure** \n(Location: `/Users/jan/prg/CC/cc-backend/internal/repository/config.go`, lines 12-37)\n\n```go\ntype RepositoryConfig struct {\n CacheSize int // Bytes, default: 1MB (1024 * 1024)\n MaxOpenConnections int // Default: 4\n MaxIdleConnections int // Default: 4\n ConnectionMaxLifetime time.Duration // Default: 1 hour\n ConnectionMaxIdleTime time.Duration // Default: 10 minutes\n MinRunningJobDuration int // Seconds, default: 600 (10 minutes)\n}\n```\n\n**Default values** (lines 43-49):\n- CacheSize: 1MB\n- MaxOpenConnections: 4\n- MaxIdleConnections: 4\n- ConnectionMaxLifetime: time.Hour\n- ConnectionMaxIdleTime: 10 * time.Minute\n- MinRunningJobDuration: 600 seconds\n\n### 3. **How SetConfig and GetConfig Work**\n\n**SetConfig** (lines 59-63): Sets package-level `repoConfig` variable (initialized at line 54)\n**GetConfig** (lines 66-68): Returns the current configuration\n**DefaultConfig** (lines 41-50): Factory function for defaults\n\n### 4. **How Connect() Uses repoConfig**\n(Location: `/Users/jan/prg/CC/cc-backend/internal/repository/dbConnection.go`, lines 63-114)\n\nThe `Connect()` function reads from package-level `repoConfig`:\n- Line 70: `MaxOpenConnections: repoConfig.MaxOpenConnections`\n- Line 71: `MaxIdleConnections: repoConfig.MaxIdleConnections`\n- Line 72: `ConnectionMaxLifetime: repoConfig.ConnectionMaxLifetime`\n- Line 73: `ConnectionMaxIdleTime: repoConfig.ConnectionMaxIdleTime`\n\nThese are passed to `DatabaseOptions` struct (lines 31-37), then applied to sqlx.DB (lines 103-106):\n```go\ndbHandle.SetMaxOpenConns(opts.MaxOpenConnections)\ndbHandle.SetMaxIdleConns(opts.MaxIdleConnections)\ndbHandle.SetConnMaxLifetime(opts.ConnectionMaxLifetime)\ndbHandle.SetConnMaxIdleTime(opts.ConnectionMaxIdleTime)\n```\n\n### 5. **Missing Integration Point: No JSON Config Section**\n\nThe main config structure (`ProgramConfig` in `/Users/jan/prg/CC/cc-backend/internal/config/config.go`) does **NOT** have a repository field. The JSON schema (`internal/config/schema.go`) also has no repository section.\n\n### 6. **How Configuration Is Currently Loaded**\n(Location: `/Users/jan/prg/CC/cc-backend/cmd/cc-backend/main.go`)\n\n- Line 99: `ccconf.Init(flagConfigFile)` - Loads config via cc-lib\n- Line 101: `cfg := ccconf.GetPackageConfig(\"main\")` - Gets \"main\" section\n- Line 106: `config.Init(cfg)` - Parses into `ProgramConfig` struct\n- Line 111: `repository.Connect(config.Keys.DB)` - **Calls Connect() WITHOUT calling SetConfig()**\n\n### 7. **Byte-Size Config Pattern in Codebase**\n\nThe codebase uses **integer fields in MB** for byte-size configs:\n- `MaxFileSizeMB` in `/Users/jan/prg/CC/cc-backend/internal/config/config.go` (line 93)\n- Same in `/Users/jan/prg/CC/cc-backend/internal/taskmanager/taskManager.go` (line 18)\n- JSON schema documents as `\"type\": \"integer\"` with description mentioning \"MB\"\n\nExample from config schema (schema.go, lines 174-176):\n```json\n\"max-file-size-mb\": {\n \"description\": \"Maximum parquet file size in MB (default: 128).\",\n \"type\": \"integer\"\n}\n```\n\n### 8. **Duration Parsing Pattern**\n\nDuration values use **ISO 8601 string format** parseable by `time.ParseDuration()`:\n- `session-max-age` in schema (line 56): `\"string parsable by time.ParseDuration()\"`\n- Example from config: `\"max-age\": \"2000h\"` in auth section\n\n### 9. **Current Flow: config.json → main → initDatabase()**\n\n```\nconfig.json (main section)\n ↓\nccconf.Init() [cc-lib]\n ↓\nccconf.GetPackageConfig(\"main\")\n ↓\nconfig.Init() → ProgramConfig struct\n ↓\ninitDatabase() calls repository.Connect(config.Keys.DB)\n ↓ [NO SetConfig call]\n ↓\nConnect() uses default repoConfig\n```\n\n### Key Files\n- **Config definition**: `/Users/jan/prg/CC/cc-backend/internal/repository/config.go` (69 lines)\n- **DB connection usage**: `/Users/jan/prg/CC/cc-backend/internal/repository/dbConnection.go` (146 lines)\n- **Main initialization**: `/Users/jan/prg/CC/cc-backend/cmd/cc-backend/main.go` (520 lines)\n- **Config struct**: `/Users/jan/prg/CC/cc-backend/internal/config/config.go` (148 lines)\n- **JSON schema**: `/Users/jan/prg/CC/cc-backend/internal/config/schema.go` (182 lines)\n\n### Summary\nCurrently, `SetConfig()` is intended to be called **before `Connect()`** but is never used.

The process stays bloated until restarted. This is caused by three compounding issues in the current SQLite configuration.\n\n## Root Cause Analysis\n\n### 1. `_cache_size=1000000000` is effectively unlimited (~4TB)\n\n**File:** `internal/repository/dbConnection.go:82`\n\n```go\nconnectionURLParams.Add(\"_cache_size\", \"1000000000\")\n```\n\nSQLite's `cache_size` PRAGMA interprets **positive values as page count** (default page size = 4KB). So 1,000,000,000 pages × 4KB = ~4TB. In practice, this means \"never evict cached pages.\" After a full-table scan of 20M rows, every page touched stays in SQLite's page cache. With 4 connections (`MaxOpenConns=4`), each can independently cache gigabytes.\n\nFor comparison, the SQLite archive backend in `pkg/archive/sqliteBackend.go` uses `PRAGMA cache_size=-64000` (64MB — negative = KiB).\n\n### 2. No query context/timeout — queries run indefinitely\n\n**File:** `internal/repository/jobQuery.go:87`\n\n```go\nrows, err := query.RunWith(r.stmtCache).Query() // No context!\n```\n\nThe `ctx` parameter is available but never passed to the database layer. Squirrel supports `.QueryContext(ctx)` but it's not used. If the HTTP request times out or the client disconnects, the query keeps running and scanning pages into cache.\n\n### 3. No SQLite memory limit — no `soft_heap_limit` or `shrink_memory`\n\nSQLite has built-in memory management PRAGMAs that are not configured:\n- **`soft_heap_limit`** — asks SQLite to keep heap usage below N bytes (best-effort, releases cache pages to stay under limit)\n- **`hard_heap_limit`** — hard cap, queries fail with SQLITE_NOMEM if exceeded\n- **`shrink_memory`** — immediately releases all unused memory back to the OS\n\nNone of these are set, so SQLite allocates freely and never releases.\n\n### 4. `temp_store = memory` amplifies the problem\n\n**File:** `internal/repository/dbConnection.go:41`\n\nTemporary B-tree sorts (exactly what happens during ORDER BY on a full-table scan) are stored in RAM. With 20M rows and no sort optimization, this can be gigabytes of temporary memory on top of the page cache.\n\n### 5. Connections live for 1 hour after use\n\n`ConnMaxIdleTime = 1 hour` means a connection that just did a massive full-table scan sits idle in the pool for up to an hour, holding all its cached pages.\n\n## Proposed Changes\n\n### Fix 1: Set reasonable `cache_size` (high impact, low risk)\n\n**File:** `internal/repository/dbConnection.go:82`\n\nChange from `1000000000` (1B pages ≈ 4TB) to `-200000` (200MB in KiB notation, per connection):\n\n```go\nconnectionURLParams.Add(\"_cache_size\", \"-200000\") // 200MB per connection\n```\n\nWith 4 max connections: 4 × 200MB = 800MB max page cache. This is generous enough for normal queries but prevents runaway memory after full-table scans.\n\n### Fix 2: Add `soft_heap_limit` (high impact, low risk)\n\n**File:** `internal/repository/dbConnection.go`, in `setupSqlite()`:\n\n```go\n\"soft_heap_limit = 1073741824\", // 1GB soft limit across all connections\n```\n\nThis is a **process-wide** limit (not per-connection). SQLite will try to release cache pages to stay under 1GB total.

The process stays bloated until restarted. This is caused by three compounding issues in the current SQLite configuration.\n\n## Root Cause Analysis\n\n### 1. `_cache_size=1000000000` is effectively unlimited (~4TB)\n\n**File:** `internal/repository/dbConnection.go:82`\n\n```go\nconnectionURLParams.Add(\"_cache_size\", \"1000000000\")\n```\n\nSQLite's `cache_size` PRAGMA interprets **positive values as page count** (default page size = 4KB). So 1,000,000,000 pages × 4KB = ~4TB. In practice, this means \"never evict cached pages.\" After a full-table scan of 20M rows, every page touched stays in SQLite's page cache. With 4 connections (`MaxOpenConns=4`), each can independently cache gigabytes.\n\nFor comparison, the SQLite archive backend in `pkg/archive/sqliteBackend.go` uses `PRAGMA cache_size=-64000` (64MB — negative = KiB).\n\n### 2. No query context/timeout — queries run indefinitely\n\n**File:** `internal/repository/jobQuery.go:87`\n\n```go\nrows, err := query.RunWith(r.stmtCache).Query() // No context!\n```\n\nThe `ctx` parameter is available but never passed to the database layer. Squirrel supports `.QueryContext(ctx)` but it's not used. If the HTTP request times out or the client disconnects, the query keeps running and scanning pages into cache.\n\n### 3. No SQLite memory limit — no `soft_heap_limit` or `shrink_memory`\n\nSQLite has built-in memory management PRAGMAs that are not configured:\n- **`soft_heap_limit`** — asks SQLite to keep heap usage below N bytes (best-effort, releases cache pages to stay under limit)\n- **`hard_heap_limit`** — hard cap, queries fail with SQLITE_NOMEM if exceeded\n- **`shrink_memory`** — immediately releases all unused memory back to the OS\n\nNone of these are set, so SQLite allocates freely and never releases.\n\n### 4. `temp_store = memory` amplifies the problem\n\n**File:** `internal/repository/dbConnection.go:41`\n\nTemporary B-tree sorts (exactly what happens during ORDER BY on a full-table scan) are stored in RAM. With 20M rows and no sort optimization, this can be gigabytes of temporary memory on top of the page cache.\n\n### 5. Connections live for 1 hour after use\n\n`ConnMaxIdleTime = 1 hour` means a connection that just did a massive full-table scan sits idle in the pool for up to an hour, holding all its cached pages.\n\n## Proposed Changes\n\n### Fix 1: Set reasonable `cache_size` (high impact, low risk)\n\n**File:** `internal/repository/dbConnection.go:82`\n\nChange from `1000000000` (1B pages ≈ 4TB) to `-200000` (200MB in KiB notation, per connection):\n\n```go\nconnectionURLParams.Add(\"_cache_size\", \"-200000\") // 200MB per connection\n```\n\nWith 4 max connections: 4 × 200MB = 800MB max page cache. This is generous enough for normal queries but prevents runaway memory after full-table scans.\n\n### Fix 2: Add `soft_heap_limit` (high impact, low risk)\n\n**File:** `internal/repository/dbConnection.go`, in `setupSqlite()`:\n\n```go\n\"soft_heap_limit = 1073741824\", // 1GB soft limit across all connections\n```\n\nThis is a **process-wide** limit (not per-connection). SQLite will try to release cache pages to stay under 1GB total. It's a soft limit — it won't abort queries, just evicts cache more aggressively.\n\n### Fix 3: Pass context to database queries (medium impact, medium effort)\n\nChange `.Query()` to `.QueryContext(ctx)`, `.QueryRow()` to `.QueryRowContext(ctx)`, and `.Scan()` to `.ScanContext(ctx)` for all query methods that already receive a `ctx` parameter. This allows HTTP request cancellation to stop the SQLite query.\n\n**Note:** The `stmtCache` from squirrel supports `QueryContext`/`QueryRowContext`.

Check startup log shows effective values","originalFile":"# Fix SQLite Memory Not Released After Query Timeout\n\n## Context\n\nOn the production 20M-row database, when a query runs into a timeout (due to full-table scan with wrong index), the memory allocated by SQLite is **not released afterwards**. The process stays bloated until restarted. This is caused by three compounding issues in the current SQLite configuration.\n\n## Root Cause Analysis\n\n### 1. `_cache_size=1000000000` is effectively unlimited (~4TB)\n\n**File:** `internal/repository/dbConnection.go:82`\n\n```go\nconnectionURLParams.Add(\"_cache_size\", \"1000000000\")\n```\n\nSQLite's `cache_size` PRAGMA interprets **positive values as page count** (default page size = 4KB). So 1,000,000,000 pages × 4KB = ~4TB. In practice, this means \"never evict cached pages.\" After a full-table scan of 20M rows, every page touched stays in SQLite's page cache. With 4 connections (`MaxOpenConns=4`), each can independently cache gigabytes.\n\nFor comparison, the SQLite archive backend in `pkg/archive/sqliteBackend.go` uses `PRAGMA cache_size=-64000` (64MB — negative = KiB).\n\n### 2. No query context/timeout — queries run indefinitely\n\n**File:** `internal/repository/jobQuery.go:87`\n\n```go\nrows, err := query.RunWith(r.stmtCache).Query() // No context!\n```\n\nThe `ctx` parameter is available but never passed to the database layer. Squirrel supports `.QueryContext(ctx)` but it's not used. If the HTTP request times out or the client disconnects, the query keeps running and scanning pages into cache.\n\n### 3. No SQLite memory limit — no `soft_heap_limit` or `shrink_memory`\n\nSQLite has built-in memory management PRAGMAs that are not configured:\n- **`soft_heap_limit`** — asks SQLite to keep heap usage below N bytes (best-effort, releases cache pages to stay under limit)\n- **`hard_heap_limit`** — hard cap, queries fail with SQLITE_NOMEM if exceeded\n- **`shrink_memory`** — immediately releases all unused memory back to the OS\n\nNone of these are set, so SQLite allocates freely and never releases.\n\n### 4. `temp_store = memory` amplifies the problem\n\n**File:** `internal/repository/dbConnection.go:41`\n\nTemporary B-tree sorts (exactly what happens during ORDER BY on a full-table scan) are stored in RAM. With 20M rows and no sort optimization, this can be gigabytes of temporary memory on top of the page cache.\n\n### 5. Connections live for 1 hour after use\n\n`ConnMaxIdleTime = 1 hour` means a connection that just did a massive full-table scan sits idle in the pool for up to an hour, holding all its cached pages.\n\n## Proposed Changes\n\n### Fix 1: Set reasonable `cache_size` (high impact, low risk)\n\n**File:** `internal/repository/dbConnection.go:82`\n\nChange from `1000000000` (1B pages ≈ 4TB) to `-200000` (200MB in KiB notation, per connection):\n\n```go\nconnectionURLParams.Add(\"_cache_size\", \"-200000\") // 200MB per connection\n```\n\nWith 4 max connections: 4 × 200MB = 800MB max page cache. This is generous enough for normal queries but prevents runaway memory after full-table scans.\n\n### Fix 2: Add `soft_heap_limit` (high impact, low risk)\n\n**File:** `internal/repository/dbConnection.go`, in `setupSqlite()`:\n\n```go\n\"soft_heap_limit = 1073741824\", // 1GB soft limit across all connections\n```\n\nThis is a **process-wide** limit (not per-connection). SQLite will try to release cache pages to stay under 1GB total. It's a soft limit — it won't abort queries, just evicts cache more aggressively.\n\n### Fix 3: Pass context to database queries (medium impact, medium effort)\n\nChange `.Query()` to `.QueryContext(ctx)`, `.QueryRow()` to `.QueryRowContext(ctx)`, and `.Scan()` to `.ScanContext(ctx)` for all query methods that already receive a `ctx` parameter. This allows HTTP request cancellation to stop the SQLite query.\n\n**Note:** The `stmtCache` from squirrel supports `QueryContext`/`QueryRowContext`. Only methods that already have `ctx` are changed — no signature changes needed.\n\n**Call sites to update** (methods that have `ctx` and call `.Query()`/`.QueryRow()`/`.Scan()`):\n\n| File | Method | Line | Change |\n|------|--------|------|--------|\n| `jobQuery.go` | `QueryJobs` | 87 | `.Query()` → `.QueryContext(ctx)` |\n| `jobQuery.go` | `CountJobs` | 129 | `.Scan()` → `.ScanContext(ctx)` |\n| `stats.go` | `JobsStatsGrouped` | 233 | `.Query()` → `.QueryContext(ctx)` |\n| `stats.go` | `JobsStats` | 358 | `.QueryRow()` → `.QueryRowContext(ctx)` |\n| `stats.go` | `JobCountGrouped` | 443 | `.Query()` → `.QueryContext(ctx)` |\n| `stats.go` | `AddJobCountGrouped` | 504 | `.Query()` → `.QueryContext(ctx)` |\n| `stats.go` | `AddJobCount` | 569 | `.Scan()` → `.ScanContext(ctx)` |\n| `stats.go` | `jobsStatisticsHistogram` | 758 | `.Query()` → `.QueryContext(ctx)` |\n| `stats.go` | `jobsDurationStatisticsHistogram` | 832 | `.Query()` → `.QueryContext(ctx)` |\n| `stats.go` | `jobsMetricStatisticsHistogram` | 962 | `.Query()` → `.QueryContext(ctx)` |\n| `jobFind.go` | `FindByID` | 174 | `.QueryRow()` → `.QueryRowContext(ctx)` |\n| `jobFind.go` | `FindByJobID` | 220 | `.QueryRow()` → `.QueryRowContext(ctx)` |\n| `job.go` | `CountGroupedJobs` | 410 | `.Scan()` → `.ScanContext(ctx)` (needs ctx added to signature) |\n| `job.go` | `GetJobList` | 751 | `.Query()` → `.QueryContext(ctx)` (needs ctx added to signature) |\n\nMethods without `ctx` in their signature (e.g., `GetJobList`, `CountGroupedJobs`) can either have `ctx` added or be left for a follow-up. The priority is the methods already accepting `ctx`.\n\n### Fix 4: Reduce `ConnMaxIdleTime`\n\n**File:** `internal/repository/config.go`\n\nReduce `ConnectionMaxIdleTime` from 1 hour to 10 minutes. Idle connections with cached pages are released sooner.\n\n## Scope — All Four Fixes\n\nAll fixes are complementary, independent, and low-risk.

The hardcoded defaults (200MB cache per connection, 1GB soft heap limit) are conservative. On the production server with 512GB RAM, these could be tuned higher for better query performance. Additionally, `RepositoryConfig` and `SetConfig()` exist but are **never wired up** — there's currently no way to override any repository defaults from config.json.\n\n## Current State (already implemented)\n\n- `_cache_size = -200000` (200MB per connection, hardcoded in `dbConnection.go:82`)\n- `soft_heap_limit = 1073741824` (1GB process-wide, hardcoded in `setupSqlite()`)\n- `ConnectionMaxIdleTime = 10 * time.Minute` (hardcoded default in `config.go`)\n- `MaxOpenConnections = 4` (hardcoded default in `config.go`)\n- Context propagation to all query call sites (already done)\n\n## Problem\n\n`repository.SetConfig()` exists but is never called from `main.go`. The `initDatabase()` function (line 110) just calls `repository.Connect(config.Keys.DB)` directly. There's no `\"db-config\"` section in `ProgramConfig` or the JSON schema.\n\n## Proposed Changes\n\n### 1. Add SQLite memory fields to `RepositoryConfig`\n\n**File:** `internal/repository/config.go`\n\nAdd two new fields with sensible defaults:\n\n```go\ntype RepositoryConfig struct {\n // ... existing fields ...\n\n // DbCacheSizeMB is the SQLite page cache size per connection in MB.\n // Uses negative PRAGMA cache_size notation (KiB). With MaxOpenConnections=4\n // and DbCacheSizeMB=200, total page cache is up to 800MB.\n // Default: 200 (MB)\n DbCacheSizeMB int\n\n // DbSoftHeapLimitMB is the process-wide SQLite soft heap limit in MB.\n // SQLite will try to release cache pages to stay under this limit.\n // It's a soft limit — queries won't fail, but cache eviction becomes more aggressive.\n // Default: 1024 (1GB)\n DbSoftHeapLimitMB int\n}\n```\n\nUpdate `DefaultConfig()`:\n```go\nDbCacheSizeMB: 200, // 200MB per connection\nDbSoftHeapLimitMB: 1024, // 1GB process-wide\n```\n\n### 2. Use config values in `Connect()` and `setupSqlite()`\n\n**File:** `internal/repository/dbConnection.go`\n\nIn `Connect()`, replace the hardcoded cache_size:\n```go\ncacheSizeKiB := repoConfig.DbCacheSizeMB * 1024 // Convert MB to KiB\nconnectionURLParams.Add(\"_cache_size\", fmt.Sprintf(\"-%d\", cacheSizeKiB))\n```\n\nChange `setupSqlite()` to accept the config and use it for soft_heap_limit:\n```go\nfunc setupSqlite(db *sql.DB, cfg *RepositoryConfig) error {\n pragmas := []string{\n \"temp_store = memory\",\n fmt.Sprintf(\"soft_heap_limit = %d\", cfg.DbSoftHeapLimitMB*1024*1024),\n }\n // ...\n}\n```\n\nUpdate the call site in `Connect()`:\n```go\nerr = setupSqlite(dbHandle.DB, &opts) // was: setupSqlite(dbHandle.DB)\n```\n\n### 3. Add `\"db-config\"` section to `ProgramConfig` and JSON schema\n\n**File:** `internal/config/config.go`\n\nAdd a new struct and field to `ProgramConfig`:\n\n```go\ntype DbConfig struct {\n CacheSizeMB int `json:\"cache-size-mb\"`\n SoftHeapLimitMB int `json:\"soft-heap-limit-mb\"`\n MaxOpenConnections int `json:\"max-open-connections\"`\n MaxIdleConnections int `json:\"max-idle-connections\"`\n ConnectionMaxIdleTimeMins int `json:\"max-idle-time-minutes\"`\n}\n\ntype ProgramConfig struct {\n // ... existing fields ...\n DbConfig *DbConfig `json:\"db-config\"`\n}\n```\n\n**File:** `internal/config/schema.go`\n\nAdd the schema section for validation.\n\n### 4. Wire `SetConfig()` in `initDatabase()`\n\n**File:** `cmd/cc-backend/main.go`\n\n```go\nfunc initDatabase() error {\n if config.Keys.DbConfig != nil {\n cfg := repository.DefaultConfig()\n dc := config.Keys.DbConfig\n if dc.CacheSizeMB > 0 {\n cfg.DbCacheSizeMB = dc.CacheSizeMB\n }\n if dc.SoftHeapLimitMB > 0 {\n cfg.DbSoftHeapLimitMB = dc.SoftHeapLimitMB\n }\n if dc.MaxOpenConnections > 0 {\n cfg.MaxOpenConnections = dc.MaxOpenConnections\n }\n if dc.MaxIdleConnections > 0 {\n cfg.MaxIdleConnections = dc.MaxIdleConnections\n }\n if dc.ConnectionMaxIdleTimeMins > 0 {\n cfg.ConnectionMaxIdleTime = time.Duration(dc.ConnectionMaxIdleTimeMins) * time.Minute\n }\n repository.SetConfig(cfg)\n }\n repository.Connect(config.Keys.DB)\n return nil\n}\n```\n\n### 5. Log effective values on startup\n\n**File:** `internal/repository/dbConnection.go`\n\nAfter setting PRAGMAs, log the effective values so operators can verify:\n```go\ncclog.Infof(\"SQLite config: cache_size=%dMB/conn, soft_heap_limit=%dMB, max_conns=%d\",\n repoConfig.DbCacheSizeMB, repoConfig.DbSoftHeapLimitMB, repoConfig.MaxOpenConnections)\n```\n\n## Example config.json (for 512GB server)\n\n```json\n{\n \"main\": {\n \"db\": \"./var/job.db\",\n \"db-config\": {\n \"cache-size-mb\": 2048,\n \"soft-heap-limit-mb\": 16384,\n \"max-open-connections\": 8,\n \"max-idle-time-minutes\": 30\n }\n }\n}\n```\n\nThis would give: 8 connections × 2GB cache = 16GB max page cache, with a 16GB soft heap limit. On a 512GB server that's ~3% of RAM — plenty of headroom.\n\n## Files to Modify\n\n| File | Changes |\n|------|---------|\n| `internal/repository/config.go` | Add `DbCacheSizeMB`, `DbSoftHeapLimitMB` fields + defaults |\n| `internal/repository/dbConnection.go` | Use config values instead of hardcoded; pass config to `setupSqlite`; add startup log |\n| `internal/config/config.go` | Add `DbConfig` struct and field to `ProgramConfig` |\n| `internal/config/schema.go` | Add `\"db-config\"` JSON schema section |\n| `cmd/cc-backend/main.go` | Wire `SetConfig()` in `initDatabase()` |\n\n## Verification\n\n1. `go build ./...` — compiles\n2. `go test ./internal/repository/... ./internal/config/...` — tests pass\n3.

The `initDatabase()` function (line 110) just calls `repository.Connect(config.Keys.DB)` directly. There's no `\"db-config\"` section in `ProgramConfig` or the JSON schema.\n\n## Proposed Changes\n\n### 1. Add SQLite memory fields to `RepositoryConfig`\n\n**File:** `internal/repository/config.go`\n\nAdd two new fields with sensible defaults:\n\n```go\ntype RepositoryConfig struct {\n // ... existing fields ...\n\n // DbCacheSizeMB is the SQLite page cache size per connection in MB.\n // Uses negative PRAGMA cache_size notation (KiB). With MaxOpenConnections=4\n // and DbCacheSizeMB=200, total page cache is up to 800MB.\n // Default: 200 (MB)\n DbCacheSizeMB int\n\n // DbSoftHeapLimitMB is the process-wide SQLite soft heap limit in MB.\n // SQLite will try to release cache pages to stay under this limit.\n // It's a soft limit — queries won't fail, but cache eviction becomes more aggressive.\n // Default: 1024 (1GB)\n DbSoftHeapLimitMB int\n}\n```\n\nUpdate `DefaultConfig()`:\n```go\nDbCacheSizeMB: 2048, // 2GB per connection\nDbSoftHeapLimitMB: 16384, // 16GB process-wide\n```\n\n**Rationale for defaults:** With an 80GB production database on a 512GB server, we want the cache to hold a significant portion of the DB. At 4 connections × 2GB = 8GB default page cache, plus 16GB soft heap limit. The previous 200MB/1GB hardcoded values were too conservative and would hurt query performance by forcing excessive cache eviction. These defaults use ~5% of a 512GB server — still safe for smaller machines, while enabling good performance on production.\n\n### 2. Use config values in `Connect()` and `setupSqlite()`\n\n**File:** `internal/repository/dbConnection.go`\n\nIn `Connect()`, replace the hardcoded cache_size:\n```go\ncacheSizeKiB := repoConfig.DbCacheSizeMB * 1024 // Convert MB to KiB\nconnectionURLParams.Add(\"_cache_size\", fmt.Sprintf(\"-%d\", cacheSizeKiB))\n```\n\nChange `setupSqlite()` to accept the config and use it for soft_heap_limit:\n```go\nfunc setupSqlite(db *sql.DB, cfg *RepositoryConfig) error {\n pragmas := []string{\n \"temp_store = memory\",\n fmt.Sprintf(\"soft_heap_limit = %d\", cfg.DbSoftHeapLimitMB*1024*1024),\n }\n // ...\n}\n```\n\nUpdate the call site in `Connect()`:\n```go\nerr = setupSqlite(dbHandle.DB, &opts) // was: setupSqlite(dbHandle.DB)\n```\n\n### 3. Add `\"db-config\"` section to `ProgramConfig` and JSON schema\n\n**File:** `internal/config/config.go`\n\nAdd a new struct and field to `ProgramConfig`:\n\n```go\ntype DbConfig struct {\n CacheSizeMB int `json:\"cache-size-mb\"`\n SoftHeapLimitMB int `json:\"soft-heap-limit-mb\"`\n MaxOpenConnections int `json:\"max-open-connections\"`\n MaxIdleConnections int `json:\"max-idle-connections\"`\n ConnectionMaxIdleTimeMins int `json:\"max-idle-time-minutes\"`\n}\n\ntype ProgramConfig struct {\n // ... existing fields ...\n DbConfig *DbConfig `json:\"db-config\"`\n}\n```\n\n**File:** `internal/config/schema.go`\n\nAdd the schema section for validation.\n\n### 4. Wire `SetConfig()` in `initDatabase()`\n\n**File:** `cmd/cc-backend/main.go`\n\n```go\nfunc initDatabase() error {\n if config.Keys.DbConfig != nil {\n cfg := repository.DefaultConfig()\n dc := config.Keys.DbConfig\n if dc.CacheSizeMB > 0 {\n cfg.DbCacheSizeMB = dc.CacheSizeMB\n }\n if dc.SoftHeapLimitMB > 0 {\n cfg.DbSoftHeapLimitMB = dc.SoftHeapLimitMB\n }\n if dc.MaxOpenConnections > 0 {\n cfg.MaxOpenConnections = dc.MaxOpenConnections\n }\n if dc.MaxIdleConnections > 0 {\n cfg.MaxIdleConnections = dc.MaxIdleConnections\n }\n if dc.ConnectionMaxIdleTimeMins > 0 {\n cfg.ConnectionMaxIdleTime = time.Duration(dc.ConnectionMaxIdleTimeMins) * time.Minute\n }\n repository.SetConfig(cfg)\n }\n repository.Connect(config.Keys.DB)\n return nil\n}\n```\n\n### 5. Log effective values on startup\n\n**File:** `internal/repository/dbConnection.go`\n\nAfter setting PRAGMAs, log the effective values so operators can verify:\n```go\ncclog.Infof(\"SQLite config: cache_size=%dMB/conn, soft_heap_limit=%dMB, max_conns=%d\",\n repoConfig.DbCacheSizeMB, repoConfig.DbSoftHeapLimitMB, repoConfig.MaxOpenConnections)\n```\n\n## Example config.json (for 512GB server with 80GB database)\n\n```json\n{\n \"main\": {\n \"db\": \"./var/job.db\",\n \"db-config\": {\n \"cache-size-mb\": 16384,\n \"soft-heap-limit-mb\": 131072,\n \"max-open-connections\": 8,\n \"max-idle-time-minutes\": 30\n }\n }\n}\n```\n\nThis would give: 8 connections × 16GB cache = 128GB max page cache, with a 128GB soft heap limit. The entire 80GB database can be cached in memory. On a 512GB server that's ~25% of RAM.\n\n**Sizing guidance (for documentation):**\n- `cache-size-mb`: Set to `DB_size / max-open-connections` to allow the entire DB to be cached. E.g., 80GB DB with 8 connections → 10GB per connection minimum.\n- `soft-heap-limit-mb`: Set to total desired SQLite memory budget. Should be ≥ `cache-size-mb × max-open-connections` to avoid cache thrashing.\n\n## Files to Modify\n\n| File | Changes |\n|------|---------|\n| `internal/repository/config.go` | Add `DbCacheSizeMB`, `DbSoftHeapLimitMB` fields + defaults |\n| `internal/repository/dbConnection.go` | Use config values instead of hardcoded; pass config to `setupSqlite`; add startup log |\n| `internal/config/config.go` | Add `DbConfig` struct and field to `ProgramConfig` |\n| `internal/config/schema.go` | Add `\"db-config\"` JSON schema section |\n| `cmd/cc-backend/main.go` | Wire `SetConfig()` in `initDatabase()` |\n\n## Verification\n\n1. `go build ./...` — compiles\n2. `go test ./internal/repository/... ./internal/config/...` — tests pass\n3.

On a 512GB server that's ~25% of RAM.\n\n**Sizing guidance (for documentation):**\n- `cache-size-mb`: Set to `DB_size / max-open-connections` to allow the entire DB to be cached. E.g., 80GB DB with 8 connections → 10GB per connection minimum.\n- `soft-heap-limit-mb`: Set to total desired SQLite memory budget. Should be ≥ `cache-size-mb × max-open-connections` to avoid cache thrashing.\n\n## Files to Modify\n\n| File | Changes |\n|------|---------|\n| `internal/repository/config.go` | Add `DbCacheSizeMB`, `DbSoftHeapLimitMB` fields + defaults |\n| `internal/repository/dbConnection.go` | Use config values instead of hardcoded; pass config to `setupSqlite`; add startup log |\n| `internal/config/config.go` | Add `DbConfig` struct and field to `ProgramConfig` |\n| `internal/config/schema.go` | Add `\"db-config\"` JSON schema section |\n| `cmd/cc-backend/main.go` | Wire `SetConfig()` in `initDatabase()` |\n\n## Verification\n\n1. `go build ./...` — compiles\n2. `go test ./internal/repository/... ./internal/config/...` — tests pass\n3. Without `db-config` in config.json: defaults apply (200MB cache, 1GB heap) — backwards compatible\n4. With `db-config`: verify with `PRAGMA cache_size;` and `PRAGMA soft_heap_limit;` in sqlite3 CLI\n5. Check startup log shows effective values\n"},"caller":{"type":"direct"}}],"stop_reason":"tool_use","stop_sequence":null,"usage":{"input_tokens":3,"cache_creation_input_tokens":831,"cache_read_input_tokens":76058,"output_tokens":39,"server_tool_use":{"web_search_requests":0,"web_fetch_requests":0},"service_tier":"standard","cache_creation":{"ephemeral_1h_input_tokens":0,"ephemeral_5m_input_tokens":831},"inference_geo":"","iterations":[],"speed":"standard"}},"requestId":"req_011CYviQoUvhoXvjVDZ2FyXX","type":"assistant","uuid":"a75bcb1d-fa24-448d-ab80-1449274f64e8","timestamp":"2026-03-11T05:08:45.604Z"} +{"parentUuid":"a75bcb1d-fa24-448d-ab80-1449274f64e8","isSidechain":false,"userType":"external","cwd":"/Users/jan/prg/CC/cc-backend","sessionId":"520afa6a-6a70-437b-96c1-35c40ed3ec48","version":"2.1.72","gitBranch":"optimize-db-indices","slug":"refactored-wishing-journal","type":"user","message":{"role":"user","content":[{"type":"tool_result","content":"The user doesn't want to proceed with this tool use.

With MaxOpenConnections=4\n // and DbCacheSizeMB=200, total page cache is up to 800MB.\n // Default: 200 (MB)\n DbCacheSizeMB int\n\n // DbSoftHeapLimitMB is the process-wide SQLite soft heap limit in MB.\n // SQLite will try to release cache pages to stay under this limit.\n // It's a soft limit — queries won't fail, but cache eviction becomes more aggressive.\n // Default: 1024 (1GB)\n DbSoftHeapLimitMB int\n}\n```\n\nUpdate `DefaultConfig()`:\n```go\nDbCacheSizeMB: 2048, // 2GB per connection\nDbSoftHeapLimitMB: 16384, // 16GB process-wide\n```\n\n**Rationale for defaults:** With an 80GB production database on a 512GB server, we want the cache to hold a significant portion of the DB. At 4 connections × 2GB = 8GB default page cache, plus 16GB soft heap limit. The previous 200MB/1GB hardcoded values were too conservative and would hurt query performance by forcing excessive cache eviction. These defaults use ~5% of a 512GB server — still safe for smaller machines, while enabling good performance on production.\n\n### 2. Use config values in `Connect()` and `setupSqlite()`\n\n**File:** `internal/repository/dbConnection.go`\n\nIn `Connect()`, replace the hardcoded cache_size:\n```go\ncacheSizeKiB := repoConfig.DbCacheSizeMB * 1024 // Convert MB to KiB\nconnectionURLParams.Add(\"_cache_size\", fmt.Sprintf(\"-%d\", cacheSizeKiB))\n```\n\nChange `setupSqlite()` to accept the config and use it for soft_heap_limit:\n```go\nfunc setupSqlite(db *sql.DB, cfg *RepositoryConfig) error {\n pragmas := []string{\n \"temp_store = memory\",\n fmt.Sprintf(\"soft_heap_limit = %d\", cfg.DbSoftHeapLimitMB*1024*1024),\n }\n // ...\n}\n```\n\nUpdate the call site in `Connect()`:\n```go\nerr = setupSqlite(dbHandle.DB, &opts) // was: setupSqlite(dbHandle.DB)\n```\n\n### 3. Add `\"db-config\"` section to `ProgramConfig` and JSON schema\n\n**File:** `internal/config/config.go`\n\nAdd a new struct and field to `ProgramConfig`:\n\n```go\ntype DbConfig struct {\n CacheSizeMB int `json:\"cache-size-mb\"`\n SoftHeapLimitMB int `json:\"soft-heap-limit-mb\"`\n MaxOpenConnections int `json:\"max-open-connections\"`\n MaxIdleConnections int `json:\"max-idle-connections\"`\n ConnectionMaxIdleTimeMins int `json:\"max-idle-time-minutes\"`\n}\n\ntype ProgramConfig struct {\n // ... existing fields ...\n DbConfig *DbConfig `json:\"db-config\"`\n}\n```\n\n**File:** `internal/config/schema.go`\n\nAdd the schema section for validation.\n\n### 4. Wire `SetConfig()` in `initDatabase()`\n\n**File:** `cmd/cc-backend/main.go`\n\n```go\nfunc initDatabase() error {\n if config.Keys.DbConfig != nil {\n cfg := repository.DefaultConfig()\n dc := config.Keys.DbConfig\n if dc.CacheSizeMB > 0 {\n cfg.DbCacheSizeMB = dc.CacheSizeMB\n }\n if dc.SoftHeapLimitMB > 0 {\n cfg.DbSoftHeapLimitMB = dc.SoftHeapLimitMB\n }\n if dc.MaxOpenConnections > 0 {\n cfg.MaxOpenConnections = dc.MaxOpenConnections\n }\n if dc.MaxIdleConnections > 0 {\n cfg.MaxIdleConnections = dc.MaxIdleConnections\n }\n if dc.ConnectionMaxIdleTimeMins > 0 {\n cfg.ConnectionMaxIdleTime = time.Duration(dc.ConnectionMaxIdleTimeMins) * time.Minute\n }\n repository.SetConfig(cfg)\n }\n repository.Connect(config.Keys.DB)\n return nil\n}\n```\n\n### 5. Log effective values on startup\n\n**File:** `internal/repository/dbConnection.go`\n\nAfter setting PRAGMAs, log the effective values so operators can verify:\n```go\ncclog.Infof(\"SQLite config: cache_size=%dMB/conn, soft_heap_limit=%dMB, max_conns=%d\",\n repoConfig.DbCacheSizeMB, repoConfig.DbSoftHeapLimitMB, repoConfig.MaxOpenConnections)\n```\n\n## Example config.json (for 512GB server with 80GB database)\n\n```json\n{\n \"main\": {\n \"db\": \"./var/job.db\",\n \"db-config\": {\n \"cache-size-mb\": 16384,\n \"soft-heap-limit-mb\": 131072,\n \"max-open-connections\": 8,\n \"max-idle-time-minutes\": 30\n }\n }\n}\n```\n\nThis would give: 8 connections × 16GB cache = 128GB max page cache, with a 128GB soft heap limit. The entire 80GB database can be cached in memory. On a 512GB server that's ~25% of RAM.\n\n**Sizing guidance (for documentation):**\n- `cache-size-mb`: Set to `DB_size / max-open-connections` to allow the entire DB to be cached. E.g., 80GB DB with 8 connections → 10GB per connection minimum.\n- `soft-heap-limit-mb`: Set to total desired SQLite memory budget. Should be ≥ `cache-size-mb × max-open-connections` to avoid cache thrashing.\n\n## Files to Modify\n\n| File | Changes |\n|------|---------|\n| `internal/repository/config.go` | Add `DbCacheSizeMB`, `DbSoftHeapLimitMB` fields + defaults |\n| `internal/repository/dbConnection.go` | Use config values instead of hardcoded; pass config to `setupSqlite`; add startup log |\n| `internal/config/config.go` | Add `DbConfig` struct and field to `ProgramConfig` |\n| `internal/config/schema.go` | Add `\"db-config\"` JSON schema section |\n| `cmd/cc-backend/main.go` | Wire `SetConfig()` in `initDatabase()` |\n\n## Verification\n\n1. `go build ./...` — compiles\n2. `go test ./internal/repository/... ./internal/config/...` — tests pass\n3. Without `db-config` in config.json: defaults apply (200MB cache, 1GB heap) — backwards compatible\n4. With `db-config`: verify with `PRAGMA cache_size;` and `PRAGMA soft_heap_limit;` in sqlite3 CLI\n5.

The hardcoded defaults (200MB cache per connection, 1GB soft heap limit) are conservative. On the production server with 512GB RAM, these could be tuned higher for better query performance. Additionally, `RepositoryConfig` and `SetConfig()` exist but are **never wired up** — there's currently no way to override any repository defaults from config.json.\n\n## Current State (already implemented on this branch)\n\n- `_cache_size = -200000` (200MB per connection, hardcoded) — **too low for 80GB DB, will be made configurable**\n- `soft_heap_limit = 1073741824` (1GB process-wide, hardcoded) — **too low, will be made configurable**\n- `ConnectionMaxIdleTime = 10 * time.Minute` (hardcoded default)\n- `MaxOpenConnections = 4` (hardcoded default)\n- Context propagation to all query call sites (already done)\n\n## Problem\n\n`repository.SetConfig()` exists but is never called from `main.go`. The `initDatabase()` function (line 110) just calls `repository.Connect(config.Keys.DB)` directly. There's no `\"db-config\"` section in `ProgramConfig` or the JSON schema.\n\n## Proposed Changes\n\n### 1.

Wire `SetConfig()` in `initDatabase()`\n\n**File:** `cmd/cc-backend/main.go`\n\n```go\nfunc initDatabase() error {\n if config.Keys.DbConfig != nil {\n cfg := repository.DefaultConfig()\n dc := config.Keys.DbConfig\n if dc.CacheSizeMB > 0 {\n cfg.DbCacheSizeMB = dc.CacheSizeMB\n }\n if dc.SoftHeapLimitMB > 0 {\n cfg.DbSoftHeapLimitMB = dc.SoftHeapLimitMB\n }\n if dc.MaxOpenConnections > 0 {\n cfg.MaxOpenConnections = dc.MaxOpenConnections\n }\n if dc.MaxIdleConnections > 0 {\n cfg.MaxIdleConnections = dc.MaxIdleConnections\n }\n if dc.ConnectionMaxIdleTimeMins > 0 {\n cfg.ConnectionMaxIdleTime = time.Duration(dc.ConnectionMaxIdleTimeMins) * time.Minute\n }\n repository.SetConfig(cfg)\n }\n repository.Connect(config.Keys.DB)\n return nil\n}\n```\n\n### 5.

It also\nincludes a web interface for ClusterCockpit. This implementation replaces the\nprevious PHP Symfony based ClusterCockpit web interface. The reasons for\nswitching from PHP Symfony to a Golang based solution are explained\n[here](https://github.com/ClusterCockpit/ClusterCockpit/wiki/Why-we-switched-from-PHP-Symfony-to-a-Golang-based-solution).\n\n## Overview\n\nThis is a Golang web backend for the ClusterCockpit job-specific performance\nmonitoring framework. It provides a REST API and an optional NATS-based messaging\nAPI for integrating ClusterCockpit with an HPC cluster batch system and external\nanalysis scripts. Data exchange between the web front-end and the back-end is\nbased on a GraphQL API. The web frontend is also served by the backend using\n[Svelte](https://svelte.dev/) components. Layout and styling are based on\n[Bootstrap 5](https://getbootstrap.com/) using\n[Bootstrap Icons](https://icons.getbootstrap.com/).\n\nThe backend uses [SQLite 3](https://sqlite.org/) as the relational SQL database.\nWhile there are metric data backends for the InfluxDB and Prometheus time series\ndatabases, the only tested and supported setup is to use cc-metric-store as the\nmetric data backend. Documentation on how to integrate ClusterCockpit with other\ntime series databases will be added in the future.\n\nFor real-time integration with HPC systems, the backend can subscribe to\n[NATS](https://nats.io/) subjects to receive job start/stop events and node\nstate updates, providing an alternative to REST API polling.\n\nCompleted batch jobs are stored in a file-based job archive according to\n[this specification](https://github.com/ClusterCockpit/cc-specifications/tree/master/job-archive).\nThe backend supports authentication via local accounts, an external LDAP\ndirectory, and JWT tokens. Authorization for APIs is implemented with\n[JWT](https://jwt.io/) tokens created with public/private key encryption.\n\nYou find a detailed documentation on the [ClusterCockpit\nWebpage](https://clustercockpit.org).\n\n## Build requirements\n\nClusterCockpit requires a current version of the golang toolchain and node.js.\nYou can check `go.mod` to see what is the current minimal golang version needed.\nHomebrew and Archlinux usually have current golang versions. For other Linux\ndistros this often means that you have to install the golang compiler yourself.\nFortunately, this is easy with golang. Since much of the functionality is based\non the Go standard library, it is crucial for security and performance to use a\ncurrent version of golang. In addition, an old golang toolchain may limit the supported\nversions of third-party packages.\n\n## How to try ClusterCockpit with a demo setup\n\nWe provide a shell script that downloads demo data and automatically starts the\ncc-backend. You will need `wget`, `go`, `node`, `npm` in your path to\nstart the demo. The demo downloads 32MB of data (223MB on disk).\n\n```sh\ngit clone https://github.com/ClusterCockpit/cc-backend.git\ncd ./cc-backend\n./startDemo.sh\n```\n\nYou can also try the demo using the latest release binary.\nCreate a folder and put the release binary `cc-backend` into this folder.\nExecute the following steps:\n\n```shell\n./cc-backend -init\nvim config.json (Add a second cluster entry and name the clusters alex and fritz)\nwget https://hpc-mover.rrze.uni-erlangen.de/HPC-Data/0x7b58aefb/eig7ahyo6fo2bais0ephuf2aitohv1ai/job-archive-demo.tar\ntar xf job-archive-demo.tar\n./cc-backend -init-db -add-user demo:admin:demo -loglevel info\n./cc-backend -server -dev -loglevel info\n```\n\nYou can access the web interface at [http://localhost:8080](http://localhost:8080).\nCredentials for login are `demo:demo`.\nPlease note that some views do not work without a metric backend (e.g., the\nAnalysis, Systems and Status views).\n\n## How to build and run\n\nThere is a Makefile to automate the build of cc-backend. The Makefile supports\nthe following targets:\n\n- `make`: Initialize `var` directory and build svelte frontend and backend\n binary. Note that there is no proper prerequisite handling. Any change of\n frontend source files will result in a complete rebuild.\n- `make clean`: Clean go build cache and remove binary.\n- `make test`: Run the tests that are also run in the GitHub workflow setup.\n\nA common workflow for setting up cc-backend from scratch is:\n\n```sh\ngit clone https://github.com/ClusterCockpit/cc-backend.git\n\n# Build binary\ncd ./cc-backend/\nmake\n\n# EDIT THE .env FILE BEFORE YOU DEPLOY (Change the secrets)!\n# If authentication is disabled, it can be empty.\ncp configs/env-template.txt .env\nvim .env\n\ncp configs/config.json .\nvim config.json\n\n#Optional: Link an existing job archive:\nln -s ./var/job-archive\n\n# This will first initialize the job.db database by traversing all\n# `meta.json` files in the job-archive and add a new user.\n./cc-backend -init-db -add-user :admin:\n\n# Start a HTTP server (HTTPS can be enabled in the configuration, the default port is 8080).\n# The --dev flag enables GraphQL Playground (http://localhost:8080/playground) and Swagger UI (http://localhost:8080/swagger).\n./cc-backend -server -dev\n\n# Show other options:\n./cc-backend -help\n```\n\n## Project file structure\n\n- [`.github/`](https://github.com/ClusterCockpit/cc-backend/tree/master/.github)\n GitHub Actions workflows and dependabot configuration for CI/CD.\n- [`api/`](https://github.com/ClusterCockpit/cc-backend/tree/master/api)\n contains the API schema files for the REST and GraphQL APIs.

Add SQLite memory fields to `RepositoryConfig` + +**File:** `internal/repository/config.go` + +Add two new fields with sensible defaults: + +```go +type RepositoryConfig struct { + // ... existing fields ... + + // DbCacheSizeMB is the SQLite page cache size per connection in MB. + // Uses negative PRAGMA cache_size notation (KiB). With MaxOpenConnections=4 + // and DbCacheSizeMB=200, total page cache is up to 800MB. + // Default: 200 (MB) + DbCacheSizeMB int + + // DbSoftHeapLimitMB is the process-wide SQLite soft heap limit in MB. + // SQLite will try to release cache pages to stay under this limit. + // It's a soft limit — queries won't fail, but cache eviction becomes more aggressive. + // Default: 1024 (1GB) + DbSoftHeapLimitMB int +} +``` + +Update `DefaultConfig()`: +```go +DbCacheSizeMB: 2048, // 2GB per connection +DbSoftHeapLimitMB: 16384, // 16GB process-wide +``` + +**Rationale for defaults:** With an 80GB production database on a 512GB server, we want the cache to hold a significant portion of the DB. At 4 connections × 2GB = 8GB default page cache, plus 16GB soft heap limit. The previous 200MB/1GB hardcoded values were too conservative and would hurt query performance by forcing excessive cache eviction. These defaults use ~5% of a 512GB server — still safe for smaller machines, while enabling good performance on production. + +### 2. Use config values in `Connect()` and `setupSqlite()` + +**File:** `internal/repository/dbConnection.go` + +In `Connect()`, replace the hardcoded cache_size: +```go +cacheSizeKiB := repoConfig.DbCacheSizeMB * 1024 // Convert MB to KiB +connectionURLParams.Add("_cache_size", fmt.Sprintf("-%d", cacheSizeKiB)) +``` + +Change `setupSqlite()` to accept the config and use it for soft_heap_limit: +```go +func setupSqlite(db *sql.DB, cfg *RepositoryConfig) error { + pragmas := []string{ + "temp_store = memory", + fmt.Sprintf("soft_heap_limit = %d", cfg.DbSoftHeapLimitMB*1024*1024), + } + // ... +} +``` + +Update the call site in `Connect()`: +```go +err = setupSqlite(dbHandle.DB, &opts) // was: setupSqlite(dbHandle.DB) +``` + +### 3. Add `"db-config"` section to `ProgramConfig` and JSON schema + +**File:** `internal/config/config.go` + +Add a new struct and field to `ProgramConfig`: + +```go +type DbConfig struct { + CacheSizeMB int `json:"cache-size-mb"` + SoftHeapLimitMB int `json:"soft-heap-limit-mb"` + MaxOpenConnections int `json:"max-open-connections"` + MaxIdleConnections int `json:"max-idle-connections"` + ConnectionMaxIdleTimeMins int `json:"max-idle-time-minutes"` +} + +type ProgramConfig struct { + // ... existing fields ... + DbConfig *DbConfig `json:"db-config"` +} +``` + +**File:** `internal/config/schema.go` + +Add the schema section for validation. + +### 4. Wire `SetConfig()` in `initDatabase()` + +**File:** `cmd/cc-backend/main.go` + +```go +func initDatabase() error { + if config.Keys.DbConfig != nil { + cfg := repository.DefaultConfig() + dc := config.Keys.DbConfig + if dc.CacheSizeMB > 0 { + cfg.DbCacheSizeMB = dc.CacheSizeMB + } + if dc.SoftHeapLimitMB > 0 { + cfg.DbSoftHeapLimitMB = dc.SoftHeapLimitMB + } + if dc.MaxOpenConnections > 0 { + cfg.MaxOpenConnections = dc.MaxOpenConnections + } + if dc.MaxIdleConnections > 0 { + cfg.MaxIdleConnections = dc.MaxIdleConnections + } + if dc.ConnectionMaxIdleTimeMins > 0 { + cfg.ConnectionMaxIdleTime = time.Duration(dc.ConnectionMaxIdleTimeMins) * time.Minute + } + repository.SetConfig(cfg) + } + repository.Connect(config.Keys.DB) + return nil +} +``` + +### 5. Log effective values on startup + +**File:** `internal/repository/dbConnection.go` + +After setting PRAGMAs, log the effective values so operators can verify: +```go +cclog.Infof("SQLite config: cache_size=%dMB/conn, soft_heap_limit=%dMB, max_conns=%d", + repoConfig.DbCacheSizeMB, repoConfig.DbSoftHeapLimitMB, repoConfig.MaxOpenConnections) +``` + +## Example config.json (for 512GB server with 80GB database) + +```json +{ + "main": { + "db": "./var/job.db", + "db-config": { + "cache-size-mb": 16384, + "soft-heap-limit-mb": 131072, + "max-open-connections": 8, + "max-idle-time-minutes": 30 + } + } +} +``` + +This would give: 8 connections × 16GB cache = 128GB max page cache, with a 128GB soft heap limit. The entire 80GB database can be cached in memory. On a 512GB server that's ~25% of RAM. + +**Sizing guidance (for documentation):** +- `cache-size-mb`: Set to `DB_size / max-open-connections` to allow the entire DB to be cached. E.g., 80GB DB with 8 connections → 10GB per connection minimum. +- `soft-heap-limit-mb`: Set to total desired SQLite memory budget.

Additionally, `RepositoryConfig` and `SetConfig()` exist but are **never wired up** — there's currently no way to override any repository defaults from config.json.\n\n## Current State (already implemented on this branch)\n\n- `_cache_size = -200000` (200MB per connection, hardcoded) — **too low for 80GB DB, will be made configurable**\n- `soft_heap_limit = 1073741824` (1GB process-wide, hardcoded) — **too low, will be made configurable**\n- `ConnectionMaxIdleTime = 10 * time.Minute` (hardcoded default)\n- `MaxOpenConnections = 4` (hardcoded default)\n- Context propagation to all query call sites (already done)\n\n## Problem\n\n`repository.SetConfig()` exists but is never called from `main.go`. The `initDatabase()` function (line 110) just calls `repository.Connect(config.Keys.DB)` directly. There's no `\"db-config\"` section in `ProgramConfig` or the JSON schema.\n\n## Proposed Changes\n\n### 1. Add SQLite memory fields to `RepositoryConfig`\n\n**File:** `internal/repository/config.go`\n\nAdd two new fields with sensible defaults:\n\n```go\ntype RepositoryConfig struct {\n // ... existing fields ...\n\n // DbCacheSizeMB is the SQLite page cache size per connection in MB.\n // Uses negative PRAGMA cache_size notation (KiB). With MaxOpenConnections=4\n // and DbCacheSizeMB=200, total page cache is up to 800MB.\n // Default: 200 (MB)\n DbCacheSizeMB int\n\n // DbSoftHeapLimitMB is the process-wide SQLite soft heap limit in MB.\n // SQLite will try to release cache pages to stay under this limit.\n // It's a soft limit — queries won't fail, but cache eviction becomes more aggressive.\n // Default: 1024 (1GB)\n DbSoftHeapLimitMB int\n}\n```\n\nUpdate `DefaultConfig()`:\n```go\nDbCacheSizeMB: 2048, // 2GB per connection\nDbSoftHeapLimitMB: 16384, // 16GB process-wide\n```\n\n**Rationale for defaults:** With an 80GB production database on a 512GB server, we want the cache to hold a significant portion of the DB. At 4 connections × 2GB = 8GB default page cache, plus 16GB soft heap limit. The previous 200MB/1GB hardcoded values were too conservative and would hurt query performance by forcing excessive cache eviction. These defaults use ~5% of a 512GB server — still safe for smaller machines, while enabling good performance on production.\n\n### 2. Use config values in `Connect()` and `setupSqlite()`\n\n**File:** `internal/repository/dbConnection.go`\n\nIn `Connect()`, replace the hardcoded cache_size:\n```go\ncacheSizeKiB := repoConfig.DbCacheSizeMB * 1024 // Convert MB to KiB\nconnectionURLParams.Add(\"_cache_size\", fmt.Sprintf(\"-%d\", cacheSizeKiB))\n```\n\nChange `setupSqlite()` to accept the config and use it for soft_heap_limit:\n```go\nfunc setupSqlite(db *sql.DB, cfg *RepositoryConfig) error {\n pragmas := []string{\n \"temp_store = memory\",\n fmt.Sprintf(\"soft_heap_limit = %d\", cfg.DbSoftHeapLimitMB*1024*1024),\n }\n // ...\n}\n```\n\nUpdate the call site in `Connect()`:\n```go\nerr = setupSqlite(dbHandle.DB, &opts) // was: setupSqlite(dbHandle.DB)\n```\n\n### 3. Add `\"db-config\"` section to `ProgramConfig` and JSON schema\n\n**File:** `internal/config/config.go`\n\nAdd a new struct and field to `ProgramConfig`:\n\n```go\ntype DbConfig struct {\n CacheSizeMB int `json:\"cache-size-mb\"`\n SoftHeapLimitMB int `json:\"soft-heap-limit-mb\"`\n MaxOpenConnections int `json:\"max-open-connections\"`\n MaxIdleConnections int `json:\"max-idle-connections\"`\n ConnectionMaxIdleTimeMins int `json:\"max-idle-time-minutes\"`\n}\n\ntype ProgramConfig struct {\n // ... existing fields ...\n DbConfig *DbConfig `json:\"db-config\"`\n}\n```\n\n**File:** `internal/config/schema.go`\n\nAdd the schema section for validation.\n\n### 4. Wire `SetConfig()` in `initDatabase()`\n\n**File:** `cmd/cc-backend/main.go`\n\n```go\nfunc initDatabase() error {\n if config.Keys.DbConfig != nil {\n cfg := repository.DefaultConfig()\n dc := config.Keys.DbConfig\n if dc.CacheSizeMB > 0 {\n cfg.DbCacheSizeMB = dc.CacheSizeMB\n }\n if dc.SoftHeapLimitMB > 0 {\n cfg.DbSoftHeapLimitMB = dc.SoftHeapLimitMB\n }\n if dc.MaxOpenConnections > 0 {\n cfg.MaxOpenConnections = dc.MaxOpenConnections\n }\n if dc.MaxIdleConnections > 0 {\n cfg.MaxIdleConnections = dc.MaxIdleConnections\n }\n if dc.ConnectionMaxIdleTimeMins > 0 {\n cfg.ConnectionMaxIdleTime = time.Duration(dc.ConnectionMaxIdleTimeMins) * time.Minute\n }\n repository.SetConfig(cfg)\n }\n repository.Connect(config.Keys.DB)\n return nil\n}\n```\n\n### 5. Log effective values on startup\n\n**File:** `internal/repository/dbConnection.go`\n\nAfter setting PRAGMAs, log the effective values so operators can verify:\n```go\ncclog.Infof(\"SQLite config: cache_size=%dMB/conn, soft_heap_limit=%dMB, max_conns=%d\",\n repoConfig.DbCacheSizeMB, repoConfig.DbSoftHeapLimitMB, repoConfig.MaxOpenConnections)\n```\n\n## Example config.json (for 512GB server with 80GB database)\n\n```json\n{\n \"main\": {\n \"db\": \"./var/job.db\",\n \"db-config\": {\n \"cache-size-mb\": 16384,\n \"soft-heap-limit-mb\": 131072,\n \"max-open-connections\": 8,\n \"max-idle-time-minutes\": 30\n }\n }\n}\n```\n\nThis would give: 8 connections × 16GB cache = 128GB max page cache, with a 128GB soft heap limit. The entire 80GB database can be cached in memory. On a 512GB server that's ~25% of RAM.\n\n**Sizing guidance (for documentation):**\n- `cache-size-mb`: Set to `DB_size / max-open-connections` to allow the entire DB to be cached. E.g., 80GB DB with 8 connections → 10GB per connection minimum.\n- `soft-heap-limit-mb`: Set to total desired SQLite memory budget. Should be ≥ `cache-size-mb × max-open-connections` to avoid cache thrashing.\n\n## Files to Modify\n\n| File | Changes |\n|------|---------|\n| `internal/repository/config.go` | Add `DbCacheSizeMB`, `DbSoftHeapLimitMB` fields + defaults |\n| `internal/repository/dbConnection.go` | Use config values instead of hardcoded; pass config to `setupSqlite`; add startup log |\n| `internal/config/config.go` | Add `DbConfig` struct and field to `ProgramConfig` |\n| `internal/config/schema.go` | Add `\"db-config\"` JSON schema section |\n| `cmd/cc-backend/main.go` | Wire `SetConfig()` in `initDatabase()` |\n\n## Verification\n\n1. `go build ./...` — compiles\n2. `go test ./internal/repository/... ./internal/config/...` — tests pass\n3. Without `db-config` in config.json: defaults apply (200MB cache, 1GB heap) — backwards compatible\n4.

It also\nincludes a web interface for ClusterCockpit. This implementation replaces the\nprevious PHP Symfony based ClusterCockpit web interface. The reasons for\nswitching from PHP Symfony to a Golang based solution are explained\n[here](https://github.com/ClusterCockpit/ClusterCockpit/wiki/Why-we-switched-from-PHP-Symfony-to-a-Golang-based-solution).\n\n## Overview\n\nThis is a Golang web backend for the ClusterCockpit job-specific performance\nmonitoring framework. It provides a REST API and an optional NATS-based messaging\nAPI for integrating ClusterCockpit with an HPC cluster batch system and external\nanalysis scripts. Data exchange between the web front-end and the back-end is\nbased on a GraphQL API. The web frontend is also served by the backend using\n[Svelte](https://svelte.dev/) components. Layout and styling are based on\n[Bootstrap 5](https://getbootstrap.com/) using\n[Bootstrap Icons](https://icons.getbootstrap.com/).\n\nThe backend uses [SQLite 3](https://sqlite.org/) as the relational SQL database.\nWhile there are metric data backends for the InfluxDB and Prometheus time series\ndatabases, the only tested and supported setup is to use cc-metric-store as the\nmetric data backend. Documentation on how to integrate ClusterCockpit with other\ntime series databases will be added in the future.\n\nFor real-time integration with HPC systems, the backend can subscribe to\n[NATS](https://nats.io/) subjects to receive job start/stop events and node\nstate updates, providing an alternative to REST API polling.\n\nCompleted batch jobs are stored in a file-based job archive according to\n[this specification](https://github.com/ClusterCockpit/cc-specifications/tree/master/job-archive).\nThe backend supports authentication via local accounts, an external LDAP\ndirectory, and JWT tokens. Authorization for APIs is implemented with\n[JWT](https://jwt.io/) tokens created with public/private key encryption.\n\nYou find a detailed documentation on the [ClusterCockpit\nWebpage](https://clustercockpit.org).\n\n## Build requirements\n\nClusterCockpit requires a current version of the golang toolchain and node.js.\nYou can check `go.mod` to see what is the current minimal golang version needed.\nHomebrew and Archlinux usually have current golang versions. For other Linux\ndistros this often means that you have to install the golang compiler yourself.\nFortunately, this is easy with golang. Since much of the functionality is based\non the Go standard library, it is crucial for security and performance to use a\ncurrent version of golang. In addition, an old golang toolchain may limit the supported\nversions of third-party packages.\n\n## How to try ClusterCockpit with a demo setup\n\nWe provide a shell script that downloads demo data and automatically starts the\ncc-backend. You will need `wget`, `go`, `node`, `npm` in your path to\nstart the demo. The demo downloads 32MB of data (223MB on disk).\n\n```sh\ngit clone https://github.com/ClusterCockpit/cc-backend.git\ncd ./cc-backend\n./startDemo.sh\n```\n\nYou can also try the demo using the latest release binary.\nCreate a folder and put the release binary `cc-backend` into this folder.\nExecute the following steps:\n\n```shell\n./cc-backend -init\nvim config.json (Add a second cluster entry and name the clusters alex and fritz)\nwget https://hpc-mover.rrze.uni-erlangen.de/HPC-Data/0x7b58aefb/eig7ahyo6fo2bais0ephuf2aitohv1ai/job-archive-demo.tar\ntar xf job-archive-demo.tar\n./cc-backend -init-db -add-user demo:admin:demo -loglevel info\n./cc-backend -server -dev -loglevel info\n```\n\nYou can access the web interface at [http://localhost:8080](http://localhost:8080).\nCredentials for login are `demo:demo`.\nPlease note that some views do not work without a metric backend (e.g., the\nAnalysis, Systems and Status views).\n\n## How to build and run\n\nThere is a Makefile to automate the build of cc-backend. The Makefile supports\nthe following targets:\n\n- `make`: Initialize `var` directory and build svelte frontend and backend\n binary. Note that there is no proper prerequisite handling. Any change of\n frontend source files will result in a complete rebuild.\n- `make clean`: Clean go build cache and remove binary.\n- `make test`: Run the tests that are also run in the GitHub workflow setup.\n\nA common workflow for setting up cc-backend from scratch is:\n\n```sh\ngit clone https://github.com/ClusterCockpit/cc-backend.git\n\n# Build binary\ncd ./cc-backend/\nmake\n\n# EDIT THE .env FILE BEFORE YOU DEPLOY (Change the secrets)!\n# If authentication is disabled, it can be empty.\ncp configs/env-template.txt .env\nvim .env\n\ncp configs/config.json .\nvim config.json\n\n#Optional: Link an existing job archive:\nln -s ./var/job-archive\n\n# This will first initialize the job.db database by traversing all\n# `meta.json` files in the job-archive and add a new user.\n./cc-backend -init-db -add-user :admin:\n\n# Start a HTTP server (HTTPS can be enabled in the configuration, the default port is 8080).\n# The --dev flag enables GraphQL Playground (http://localhost:8080/playground) and Swagger UI (http://localhost:8080/swagger).\n./cc-backend -server -dev\n\n# Show other options:\n./cc-backend -help\n```\n\n## Project file structure\n\n- [`.github/`](https://github.com/ClusterCockpit/cc-backend/tree/master/.github)\n GitHub Actions workflows and dependabot configuration for CI/CD.\n- [`api/`](https://github.com/ClusterCockpit/cc-backend/tree/master/api)\n contains the API schema files for the REST and GraphQL APIs.

For large installations, SQLite memory","+usage can be tuned via the optional `db-config` section in config.json under","+`main`:","+","+```json","+{","+ \"main\": {","+ \"db\": \"./var/job.db\",","+ \"db-config\": {","+ \"cache-size-mb\": 2048,","+ \"soft-heap-limit-mb\": 16384,","+ \"max-open-connections\": 4,","+ \"max-idle-connections\": 4,","+ \"max-idle-time-minutes\": 10","+ }","+ }","+}","+```","+","+All fields are optional. If `db-config` is omitted entirely, built-in defaults","+are used.","+","+### Options","+","+| Option | Default | Description |","+|--------|---------|-------------|","+| `cache-size-mb` | 2048 | SQLite page cache size per connection in MB. Maps to `PRAGMA cache_size`. Total cache memory is up to `cache-size-mb × max-open-connections`. |","+| `soft-heap-limit-mb` | 16384 | Process-wide SQLite soft heap limit in MB.

Each connection gets its own independent page cache. With `max-open-connections = 8` and `cache-size-mb = 10240` (10GB), you get up to 8 × 10GB = 80GB of total cache across all connections.\n\nIn practice, different connections tend to cache **different pages** — one connection might cache pages for a large job listing query, while another caches pages for a statistics aggregation. The caches naturally spread across the database. So the total memory available for caching is the sum across all connections, not the per-connection value.\n\nThat said, it's an approximation — there's no guarantee of zero overlap. Two connections running similar queries will cache the same pages redundantly. The formula `DB_size / max-open-connections` gives enough per-connection cache that, in the best case, the union of all connection caches can cover the entire database. In the worst case (all connections caching identical pages), you'd only cache `cache-size-mb` worth of unique data.\n\nWant me to clarify this nuance in the README sizing

With multiple connections, the total\nmemory available for caching is the sum across all connections.\n\nIn practice, different connections tend to cache **different pages** (e.g., one\nhandles a job listing query while another runs a statistics aggregation), so\ntheir caches naturally spread across the database. The formula\n`DB_size / max-open-connections` gives enough per-connection cache that the\ncombined caches can cover the entire database.\n\nHowever, this is a best-case estimate. Connections running similar queries will\ncache the same pages redundantly. In the worst case (all connections caching\nidentical pages), only `cache-size-mb` worth of unique data is cached rather\nthan `cache-size-mb × max-open-connections`. For workloads with diverse\nconcurrent queries, cache overlap is typically low.\n\n**Rules of thumb:**\n\n- **cache-size-mb**: Set to `DB_size_in_MB / max-open-connections` to allow the\n entire database to be cached in memory. For example, an 80GB database with 8\n connections needs at least 10240 MB (10GB) per connection. If your workload\n has many similar concurrent queries, consider setting it higher to account for\n cache overlap between connections.\n- **soft-heap-limit-mb**: Should be >= `cache-size-mb × max-open-connections` to\n avoid cache thrashing. This is the total SQLite memory budget for the process.\n- On small installations the defaults work well. On servers with large databases\n (tens of GB) and plenty of RAM, increasing these values significantly improves\n query performance by reducing disk I/O.\n\n### Example: Large Server (512GB RAM, 80GB database)\n\n```json\n{\n \"main\": {\n \"db-config\": {\n \"cache-size-mb\": 16384,\n \"soft-heap-limit-mb\": 131072,\n \"max-open-connections\": 8,\n \"max-idle-time-minutes\": 30\n }\n }\n}\n```\n\nThis allows the entire 80GB database to be cached (8 × 16GB = 128GB page cache)\nwith a 128GB soft heap limit, using about 25% of available RAM.\n\nThe effective configuration is logged at startup for verification.\n\n## Project file structure"},"caller":{"type":"direct"}}],"stop_reason":"tool_use","stop_sequence":null,"usage":{"input_tokens":1,"cache_creation_input_tokens":2854,"cache_read_input_tokens":48488,"output_tokens":1901,"server_tool_use":{"web_search_requests":0,"web_fetch_requests":0},"service_tier":"standard","cache_creation":{"ephemeral_1h_input_tokens":0,"ephemeral_5m_input_tokens":2854},"inference_geo":"","iterations":[],"speed":"standard"}},"requestId":"req_011CYvwXTjzC9f1ZhJxmVJig","type":"assistant","uuid":"b09b97ee-8129-4d81-9079-dda7175ca305","timestamp":"2026-03-11T08:01:26.861Z"} +{"parentUuid":"b09b97ee-8129-4d81-9079-dda7175ca305","isSidechain":false,"userType":"external","cwd":"/Users/jan/prg/CC/cc-backend","sessionId":"50b2b10a-1be0-441f-aafb-3c5828f0fcc9","version":"2.1.72","gitBranch":"dev","slug":"refactored-wishing-journal","type":"progress","data":{"type":"hook_progress","hookEvent":"PostToolUse","hookName":"PostToolUse:Edit","command":"callback"},"parentToolUseID":"toolu_0121qHYMAEME3XEu6e441FDJ","toolUseID":"toolu_0121qHYMAEME3XEu6e441FDJ","timestamp":"2026-03-11T09:41:35.168Z","uuid":"0d3351d0-2cab-4280-80a9-32d189daace0"} +{"parentUuid":"b09b97ee-8129-4d81-9079-dda7175ca305","isSidechain":false,"userType":"external","cwd":"/Users/jan/prg/CC/cc-backend","sessionId":"50b2b10a-1be0-441f-aafb-3c5828f0fcc9","version":"2.1.72","gitBranch":"dev","slug":"refactored-wishing-journal","type":"user","message":{"role":"user","content":[{"tool_use_id":"toolu_0121qHYMAEME3XEu6e441FDJ","type":"tool_result","content":"The file /Users/jan/prg/CC/cc-backend/README.md has been updated successfully."}]},"uuid":"43cb79e5-f967-4fd1-a54c-75cb702bcbcb","timestamp":"2026-03-11T09:41:35.167Z","toolUseResult":{"filePath":"/Users/jan/prg/CC/cc-backend/README.md","oldString":"## Project file structure","newString":"## Database Configuration\n\ncc-backend uses SQLite as its database.

It also\nincludes a web interface for ClusterCockpit. This implementation replaces the\nprevious PHP Symfony based ClusterCockpit web interface. The reasons for\nswitching from PHP Symfony to a Golang based solution are explained\n[here](https://github.com/ClusterCockpit/ClusterCockpit/wiki/Why-we-switched-from-PHP-Symfony-to-a-Golang-based-solution).\n\n## Overview\n\nThis is a Golang web backend for the ClusterCockpit job-specific performance\nmonitoring framework. It provides a REST API and an optional NATS-based messaging\nAPI for integrating ClusterCockpit with an HPC cluster batch system and external\nanalysis scripts. Data exchange between the web front-end and the back-end is\nbased on a GraphQL API. The web frontend is also served by the backend using\n[Svelte](https://svelte.dev/) components. Layout and styling are based on\n[Bootstrap 5](https://getbootstrap.com/) using\n[Bootstrap Icons](https://icons.getbootstrap.com/).\n\nThe backend uses [SQLite 3](https://sqlite.org/) as the relational SQL database.\nWhile there are metric data backends for the InfluxDB and Prometheus time series\ndatabases, the only tested and supported setup is to use cc-metric-store as the\nmetric data backend. Documentation on how to integrate ClusterCockpit with other\ntime series databases will be added in the future.\n\nFor real-time integration with HPC systems, the backend can subscribe to\n[NATS](https://nats.io/) subjects to receive job start/stop events and node\nstate updates, providing an alternative to REST API polling.\n\nCompleted batch jobs are stored in a file-based job archive according to\n[this specification](https://github.com/ClusterCockpit/cc-specifications/tree/master/job-archive).\nThe backend supports authentication via local accounts, an external LDAP\ndirectory, and JWT tokens. Authorization for APIs is implemented with\n[JWT](https://jwt.io/) tokens created with public/private key encryption.\n\nYou find a detailed documentation on the [ClusterCockpit\nWebpage](https://clustercockpit.org).\n\n## Build requirements\n\nClusterCockpit requires a current version of the golang toolchain and node.js.\nYou can check `go.mod` to see what is the current minimal golang version needed.\nHomebrew and Archlinux usually have current golang versions. For other Linux\ndistros this often means that you have to install the golang compiler yourself.\nFortunately, this is easy with golang. Since much of the functionality is based\non the Go standard library, it is crucial for security and performance to use a\ncurrent version of golang. In addition, an old golang toolchain may limit the supported\nversions of third-party packages.\n\n## How to try ClusterCockpit with a demo setup\n\nWe provide a shell script that downloads demo data and automatically starts the\ncc-backend. You will need `wget`, `go`, `node`, `npm` in your path to\nstart the demo. The demo downloads 32MB of data (223MB on disk).\n\n```sh\ngit clone https://github.com/ClusterCockpit/cc-backend.git\ncd ./cc-backend\n./startDemo.sh\n```\n\nYou can also try the demo using the latest release binary.\nCreate a folder and put the release binary `cc-backend` into this folder.\nExecute the following steps:\n\n```shell\n./cc-backend -init\nvim config.json (Add a second cluster entry and name the clusters alex and fritz)\nwget https://hpc-mover.rrze.uni-erlangen.de/HPC-Data/0x7b58aefb/eig7ahyo6fo2bais0ephuf2aitohv1ai/job-archive-demo.tar\ntar xf job-archive-demo.tar\n./cc-backend -init-db -add-user demo:admin:demo -loglevel info\n./cc-backend -server -dev -loglevel info\n```\n\nYou can access the web interface at [http://localhost:8080](http://localhost:8080).\nCredentials for login are `demo:demo`.\nPlease note that some views do not work without a metric backend (e.g., the\nAnalysis, Systems and Status views).\n\n## How to build and run\n\nThere is a Makefile to automate the build of cc-backend. The Makefile supports\nthe following targets:\n\n- `make`: Initialize `var` directory and build svelte frontend and backend\n binary. Note that there is no proper prerequisite handling. Any change of\n frontend source files will result in a complete rebuild.\n- `make clean`: Clean go build cache and remove binary.\n- `make test`: Run the tests that are also run in the GitHub workflow setup.\n\nA common workflow for setting up cc-backend from scratch is:\n\n```sh\ngit clone https://github.com/ClusterCockpit/cc-backend.git\n\n# Build binary\ncd ./cc-backend/\nmake\n\n# EDIT THE .env FILE BEFORE YOU DEPLOY (Change the secrets)!\n# If authentication is disabled, it can be empty.\ncp configs/env-template.txt .env\nvim .env\n\ncp configs/config.json .\nvim config.json\n\n#Optional: Link an existing job archive:\nln -s ./var/job-archive\n\n# This will first initialize the job.db database by traversing all\n# `meta.json` files in the job-archive and add a new user.\n./cc-backend -init-db -add-user :admin:\n\n# Start a HTTP server (HTTPS can be enabled in the configuration, the default port is 8080).\n# The --dev flag enables GraphQL Playground (http://localhost:8080/playground) and Swagger UI (http://localhost:8080/swagger).\n./cc-backend -server -dev\n\n# Show other options:\n./cc-backend -help\n```\n\n## Project file structure\n\n- [`.github/`](https://github.com/ClusterCockpit/cc-backend/tree/master/.github)\n GitHub Actions workflows and dependabot configuration for CI/CD.\n- [`api/`](https://github.com/ClusterCockpit/cc-backend/tree/master/api)\n contains the API schema files for the REST and GraphQL APIs.

With multiple connections, the total","+memory available for caching is the sum across all connections.","+","+In practice, different connections tend to cache **different pages** (e.g., one","+handles a job listing query while another runs a statistics aggregation), so","+their caches naturally spread across the database. The formula","+`DB_size / max-open-connections` gives enough per-connection cache that the","+combined caches can cover the entire database.","+","+However, this is a best-case estimate. Connections running similar queries will","+cache the same pages redundantly. In the worst case (all connections caching","+identical pages), only `cache-size-mb` worth of unique data is cached rather","+than `cache-size-mb × max-open-connections`. For workloads with diverse","+concurrent queries, cache overlap is typically low.","+","+**Rules of thumb:**","+","+- **cache-size-mb**: Set to `DB_size_in_MB / max-open-connections` to allow the","+ entire database to be cached in memory. For example, an 80GB database with 8","+ connections needs at least 10240 MB (10GB) per connection. If your workload","+ has many similar concurrent queries, consider setting it higher to account for","+ cache overlap between connections.","+- **soft-heap-limit-mb**: Should be >= `cache-size-mb × max-open-connections` to","+ avoid cache thrashing. This is the total SQLite memory budget for the process.","+- On small installations the defaults work well.

At 4 connections × 2GB = 8GB default page cache, plus 16GB soft heap limit. The previous 200MB/1GB hardcoded values were too conservative and would hurt query performance by forcing excessive cache eviction. These defaults use ~5% of a 512GB server — still safe for smaller machines, while enabling good performance on production. + +### 2. Use config values in `Connect()` and `setupSqlite()` + +**File:** `internal/repository/dbConnection.go` + +In `Connect()`, replace the hardcoded cache_size: +```go +cacheSizeKiB := repoConfig.DbCacheSizeMB * 1024 // Convert MB to KiB +connectionURLParams.Add("_cache_size", fmt.Sprintf("-%d", cacheSizeKiB)) +``` + +Change `setupSqlite()` to accept the config and use it for soft_heap_limit: +```go +func setupSqlite(db *sql.DB, cfg *RepositoryConfig) error { + pragmas := []string{ + "temp_store = memory", + fmt.Sprintf("soft_heap_limit = %d", cfg.DbSoftHeapLimitMB*1024*1024), + } + // ... +} +``` + +Update the call site in `Connect()`: +```go +err = setupSqlite(dbHandle.DB, &opts) // was: setupSqlite(dbHandle.DB) +``` + +### 3. Add `"db-config"` section to `ProgramConfig` and JSON schema + +**File:** `internal/config/config.go` + +Add a new struct and field to `ProgramConfig`: + +```go +type DbConfig struct { + CacheSizeMB int `json:"cache-size-mb"` + SoftHeapLimitMB int `json:"soft-heap-limit-mb"` + MaxOpenConnections int `json:"max-open-connections"` + MaxIdleConnections int `json:"max-idle-connections"` + ConnectionMaxIdleTimeMins int `json:"max-idle-time-minutes"` +} + +type ProgramConfig struct { + // ... existing fields ... + DbConfig *DbConfig `json:"db-config"` +} +``` + +**File:** `internal/config/schema.go` + +Add the schema section for validation. + +### 4. Wire `SetConfig()` in `initDatabase()` + +**File:** `cmd/cc-backend/main.go` + +```go +func initDatabase() error { + if config.Keys.DbConfig != nil { + cfg := repository.DefaultConfig() + dc := config.Keys.DbConfig + if dc.CacheSizeMB > 0 { + cfg.DbCacheSizeMB = dc.CacheSizeMB + } + if dc.SoftHeapLimitMB > 0 { + cfg.DbSoftHeapLimitMB = dc.SoftHeapLimitMB + } + if dc.MaxOpenConnections > 0 { + cfg.MaxOpenConnections = dc.MaxOpenConnections + } + if dc.MaxIdleConnections > 0 { + cfg.MaxIdleConnections = dc.MaxIdleConnections + } + if dc.ConnectionMaxIdleTimeMins > 0 { + cfg.ConnectionMaxIdleTime = time.Duration(dc.ConnectionMaxIdleTimeMins) * time.Minute + } + repository.SetConfig(cfg) + } + repository.Connect(config.Keys.DB) + return nil +} +``` + +### 5. Log effective values on startup + +**File:** `internal/repository/dbConnection.go` + +After setting PRAGMAs, log the effective values so operators can verify: +```go +cclog.Infof("SQLite config: cache_size=%dMB/conn, soft_heap_limit=%dMB, max_conns=%d", + repoConfig.DbCacheSizeMB, repoConfig.DbSoftHeapLimitMB, repoConfig.MaxOpenConnections) +``` + +## Example config.json (for 512GB server with 80GB database) + +```json +{ + "main": { + "db": "./var/job.db", + "db-config": { + "cache-size-mb": 16384, + "soft-heap-limit-mb": 131072, + "max-open-connections": 8, + "max-idle-time-minutes": 30 + } + } +} +``` + +This would give: 8 connections × 16GB cache = 128GB max page cache, with a 128GB soft heap limit. The entire 80GB database can be cached in memory. On a 512GB server that's ~25% of RAM. + +**Sizing guidance (for documentation):** +- `cache-size-mb`: Set to `DB_size / max-open-connections` to allow the entire DB to be cached. E.g., 80GB DB with 8 connections → 10GB per connection minimum. +- `soft-heap-limit-mb`: Set to total desired SQLite memory budget. Should be ≥ `cache-size-mb × max-open-connections` to avoid cache thrashing. + +## Files to Modify + +| File | Changes | +|------|---------| +| `internal/repository/config.go` | Add `DbCacheSizeMB`, `DbSoftHeapLimitMB` fields + defaults | +| `internal/repository/dbConnection.go` | Use config values instead of hardcoded; pass config to `setupSqlite`; add startup log | +| `internal/config/config.go` | Add `DbConfig` struct and field to `ProgramConfig` | +| `internal/config/schema.go` | Add `"db-config"` JSON schema section | +| `cmd/cc-backend/main.go` | Wire `SetConfig()` in `initDatabase()` | + +## Verification + +1. `go build ./...` — compiles +2. `go test ./internal/repository/... ./internal/config/...` — tests pass +3.

Statistics can be computed:\n// - Overall (JobsStats): Single aggregate across all matching jobs\n// - Grouped (JobsStatsGrouped): Aggregated by user, project, cluster, or subcluster\n// - Counts (JobCountGrouped, AddJobCount): Simple job counts with optional filtering\n//\n// All statistics methods support filtering via JobFilter and respect security contexts.\n//\n// # Histograms\n//\n// Histogram methods generate distribution data for visualization:\n// - Duration, nodes, cores, accelerators (AddHistograms)\n// - Job metrics like CPU load, memory usage (AddMetricHistograms)\n//\n// Histograms use intelligent binning:\n// - Duration: Variable bin sizes (1m, 10m, 1h, 6h, 12h, 24h) with zero-padding\n// - Resources: Natural value-based bins\n// - Metrics: Normalized to peak values with configurable bin counts\n//\n// # Running vs. Completed Jobs\n//\n// Statistics handle running jobs specially:\n// - Duration calculated as (now - start_time) for running jobs\n// - Metric histograms for running jobs load data from metric backend instead of footprint\n// - Job state filtering distinguishes running/completed jobs\n//\n// # Performance Considerations\n//\n// - All queries use prepared statements via stmtCache\n// - Complex aggregations use SQL for efficiency\n// - Histogram pre-initialization ensures consistent bin ranges\n// - Metric histogram queries limited to 5000 jobs for running job analysis\n\npackage repository\n\nimport (\n\t\"context\"\n\t\"database/sql\"\n\t\"fmt\"\n\t\"time\"\n\n\t\"github.com/ClusterCockpit/cc-backend/internal/config\"\n\t\"github.com/ClusterCockpit/cc-backend/internal/graph/model\"\n\t\"github.com/ClusterCockpit/cc-backend/internal/metricdispatch\"\n\t\"github.com/ClusterCockpit/cc-backend/pkg/archive\"\n\tcclog \"github.com/ClusterCockpit/cc-lib/v2/ccLogger\"\n\t\"github.com/ClusterCockpit/cc-lib/v2/schema\"\n\tsq \"github.com/Masterminds/squirrel\"\n)\n\n// groupBy2column maps GraphQL Aggregate enum values to their corresponding database column names.\n// Used by JobsStatsGrouped and JobCountGrouped to translate user-facing grouping dimensions\n// into SQL GROUP BY clauses.

For project/cluster/subcluster grouping, it selects `'' as name` with no join.\n\n### Fix 3: O(1) map lookup for histogram bin matching\nBoth `jobsDurationStatisticsHistogram` and `jobsMetricStatisticsHistogram` now pre-build a `binMap` after initializing the points slice, replacing the O(n×bins) inner loop with a single map lookup per result row.\n\n### Fix 4: Single

The problem: O(n × bins) inner loop\n\nAfter querying the database, the code needs to match each query result row to its pre-initialized bin. The original code did this with a nested loop:\n\n```go\n// For each row returned by the query...\nfor rows.Next() {\n rows.Scan(&point.Value, &point.Count)\n\n // ...scan every bin to find the matching one\n for _, e := range points {\n if e.Value == (point.Value * binSizeSeconds) {\n e.Count = point.Count\n break\n }\n }\n}\n```\n\nIf the query returns `R` rows and there are `B` bins, this is **O(R × B)** — every result row triggers a full scan of the `points` slice until it finds its match. For the duration histogram with 48 bins, each of the up to 48 result rows scans up to 48 entries = up to 2,304 comparisons. Small here, but the pattern is still wasteful.\n\n### The fix: build a reverse index first\n\n```go\n// Build map once: bin value (seconds) → slice index\nbinMap := make(map[int]int, len(points))\nfor i, p := range points {\n binMap[p.Value] = i // e.g. 3600 → 0, 7200 → 1, ...\n}\n\n// Then during row scan: one map lookup per row\nfor rows.Next() {\n rows.Scan(&point.Value, &point.Count)\n if idx, ok := binMap[point.Value * binSizeSeconds]; ok {\n points[idx].Count = point.Count\n }\n}\n```\n\nBuilding the map is **O(B)** once. Each result row lookup is **O(1)** average. Total: **O(B + R)** instead of **O(R × B)**.\n\n### Why it also fixes a correctness subtlety\n\nThe original loop used `break` to stop after the first match — relying on the assumption that bin values are unique (which they are, since they're `1×size, 2×size, ...`). The map makes this uniqueness structural rather than implicit.\n\n### Practical impact\n\nFor histograms the bins are small (max ~72), so the raw speedup here is modest. The more significant benefit is in `jobsMetricStatisticsHistogram`, which is called once per metric per stats request — if someone requests 10 metrics, that's 10 × O(R×B) inner loops replaced with 10 × O(B+R). It also makes the code clearly correct on inspection rather than requiring mental simulation of the loop."}],"stop_reason":"end_turn","stop_sequence":null,"usage":{"input_tokens":3,"cache_creation_input_tokens":491,"cache_read_input_tokens":50088,"output_tokens":673,"server_tool_use":{"web_search_requests":0,"web_fetch_requests":0},"service_tier":"standard","cache_creation":{"ephemeral_1h_input_tokens":491,"ephemeral_5m_input_tokens":0},"inference_geo":"","iterations":[],"speed":"standard"}},"requestId":"req_011CYwRUJur2VkCyUXpuvc9o","type":"assistant","uuid":"cc70951b-99f4-4ae6-9b6d-a7ec9e9bfbaa","timestamp":"2026-03-11T14:07:26.672Z"}

Cluster information is now derived from the job archive.\n- **`apiAllowedIPs` is now optional**: If not specified, defaults to not\n restricted.\n\n### Architecture changes\n\n- **Web framework replaced**: Migrated from `gorilla/mux` to `chi` as the HTTP\n router. This should be transparent to users but affects how middleware and\n routes are composed. A proper 404 handler is now in place.\n- **MetricStore moved**: The `metricstore` package has been moved from `internal/`\n to `pkg/` as it is now part of the public API.\n- **MySQL/MariaDB support removed**: Only SQLite is now supported as the database backend.\n- **Archive to Cleanup renaming**: Archive-related functions have been refactored\n and renamed to \"Cleanup\" for clarity.\n- **`minRunningFor` filter removed**: This undocumented filter has been removed\n from the API and frontend.\n\n### Dependency changes\n\n- **cc-lib v2.8.0**: Switched to cc-lib version 2 with updated APIs\n- **cclib NATS client**: Now using the cclib NATS client implementation\n- Removed obsolete `util.Float` usage from cclib\n\n## Major new features\n\n### NATS API Integration\n\n- **Real-time

classification**: Automatic detection of pathological jobs\n- **omit-tagged**: Option to exclude tagged jobs from retention/cleanup operations (`none`, `all`, or `user`)\n- **Admin UI trigger**: Taggers can be run on-demand from the admin web interface\n without restarting the backend\n\n### Archive Backends\n\n- **Parquet archive format**: New Parquet file format for job archiving, providing\n columnar storage with efficient compression for analytical workloads\n- **S3 backend**: Full support for S3-compatible object storage\n- **SQLite backend**: Full support for SQLite backend using blobs\n- **Performance improvements**: Fixed performance bugs in archive backends\n- **Better error handling**: Improved error messages and fallback handling\n- **Zstd compression**: Parquet writers use zstd compression for better\n compression ratios compared to the previous snappy default\n- **Optimized sort order**: Job and nodestate Parquet files are sorted by\n cluster, subcluster, and start time for efficient range queries\n\n### Unified Archive Retention and Format Conversion\n\n- **Uniform retention policy**: Job archive retention now supports both JSON and\n Parquet as target formats under a single, consistent policy configuration\n- **Archive manager tool**: The `tools/archive-manager` utility now supports\n format conversion between JSON and Parquet job archives\n- **Parquet reader**: Full Parquet archive reader implementation for reading back\n archived job data\n\n## New features and improvements\n\n### Frontend\n\n- **Loading indicators**: Added

names\n- If using NATS, configure the new `nats` and `api-subjects` sections\n- If using S3 archive backend, configure the new `archive` section options\n- Test the new public dashboard at `/public` route\n- Review cron worker configuration if you need different frequencies\n- If using the archive retention feature, configure the `target-format` option\n to choose between `json` (default) and `parquet` output formats\n- Consider enabling nodestate retention if you track node states over time\n\n## Known issues\n\n- The new dynamic memory management is not bullet proof yet across restarts. We\n will fix that in a subsequent patch release\n- Currently energy footprint metrics of type energy are ignored for calculating\n total energy.\n- With energy footprint metrics of type power the unit is ignored and it is\n assumed the metric has the unit Watt.\n","structuredPatch":[{"oldStart":6,"oldLines":6,"newStart":6,"newLines":38,"lines":[" implementation of ClusterCockpit."," For release specific notes visit the [ClusterCockpit Documentation](https://clusterockpit.org/docs/release/)."," ","+## Changes in 1.5.1","+","+### Database","+","+- **New migration (version 11)**: Optimized database index count for better performance","+- **ANALYZE on startup**: Database statistics are now refreshed on startup for improved query planning","+- **SQLite configuration hardening**: Sanitized SQLite configuration with new configurable options; fixes large heap allocations in the SQLite driver","+- **Query cancellation**: Long-running database queries can now be cancelled","+- **Resource leak fix**: Added missing `defer Close()` calls for all query result sets","+","+### Bug fixes","+","+- **Segfault when taggers misconfigured**: Fixed crash when `enable-job-taggers` is set but tagger rule directories are missing","+- **GroupBy stats query complexity**: Reduced complexity for `groupBy` statistics queries","+- **Ranged filter conditions**: Fixed GT and LT conditions in ranged filters","+- **Energy filter preset**: Reduced energy filter preset to a more practical default","+- **JSON validity check**: Fixed wrong field being checked for JSON validity","+- **Tagger float rounding**: Fixed rounding of floats in tagger messages","+- **Node view null safety**: Added null-safe checks in node view to prevent runtime errors","+","+### Frontend","+","+- **Bumped patch versions**: Updated frontend dependencies to latest patch versions","+","+### Documentation","+","+- **New DB config options**: Added new database configuration options to README","+","+---","+","+*The sections below document all features and changes introduced in the 1.5.0 major release, which 1.5.1 is based on.*","+"," ##

The `BuildWhereClause` now inlines the literal state value (`job.job_state = 'running'`) so SQLite matches the partial index instead of using a parameterized placeholder.\n\n2. **Request-scoped cache** — `stats_cache.go` provides a `statsGroupCache` injected per GraphQL operation via `AroundOperations` middleware. When the same `(filter, groupBy)` pair is requested multiple times (e.g. topUserJobs, topUserNodes, topUserAccs), the DB query runs only once; sort+page is done in Go.\n\n3. **Parallel histograms** — `AddHistograms` now runs all 4 histogram queries concurrently using `errgroup.WithContext`.\n\n4. **Frontend consolidation** — `UsageDash.svelte` sends 2 GraphQL aliases (allUsers, allProjects)

The `BuildWhereClause` now inlines the literal state value (`job.job_state = 'running'`) so SQLite matches the partial index instead of using a parameterized placeholder.\n\n2. **Request-scoped cache** — `stats_cache.go` provides a `statsGroupCache` injected per GraphQL operation via `AroundOperations` middleware. When the same `(filter, groupBy)` pair is requested multiple times (e.g. topUserJobs, topUserNodes, topUserAccs), the DB query runs only once; sort+page is done in Go.\n\n3. **Parallel histograms** — `AddHistograms` now runs all 4 histogram queries concurrently using `errgroup.WithContext`.\n\n4. **Frontend consolidation** — `UsageDash.svelte` sends 2 GraphQL aliases (allUsers, allProjects)

All values come from either hardcoded constants or validated GraphQL enums\n2. **Mixed parameterization approach** - 5 use parameterized queries (Squirrel with ?), 9 use inlined literals\n3. **Intentional inlining in jobQuery.go:204** - Comment documents this is safe for SQLite partial index optimization\n4. **Consistent \"running\" state usage** - Almost all filters target the hardcoded \"running\" state for specific queries\n5. **One minor issue in job.go:817** - Missing \"job.\" table prefix in UpdateDuration query (though still safe as it's unambiguous)"}],"totalDurationMs":53390,"totalTokens":66263,"totalToolUseCount":17,"usage":{"input_tokens":5,"cache_creation_input_tokens":9264,"cache_read_input_tokens":53822,"output_tokens":3172,"server_tool_use":{"web_search_requests":0,"web_fetch_requests":0},"service_tier":"standard","cache_creation":{"ephemeral_1h_input_tokens":0,"ephemeral_5m_input_tokens":9264},"inference_geo":"","iterations":[],"speed":"standard"}},"sourceToolAssistantUUID":"8cbf0c52-c5b0-4c92-a63e-ba22eb7416fd","userType":"external","cwd":"/Users/jan/prg/ClusterCockpit/cc-backend","sessionId":"889ef150-c6ca-4f35-81e5-c19dc95fe399","version":"2.1.74","gitBranch":"hotfix","slug":"recursive-giggling-volcano"} +{"parentUuid":"eab5e799-0172-4a96-ad80-8a9ebe391648","isSidechain":false,"message":{"model":"claude-opus-4-6","id":"msg_01LunFsBm6KQMnHbRchWL5Qj","type":"message","role":"assistant","content":[{"type":"tool_use","id":"toolu_016KHumoJ75SUh7X9K1dBwVa","name":"Read","input":{"file_path":"/Users/jan/.claude/plans/recursive-giggling-volcano.md"},"caller":{"type":"direct"}}],"stop_reason":"tool_use","stop_sequence":null,"usage":{"input_tokens":1,"cache_creation_input_tokens":3603,"cache_read_input_tokens":96447,"output_tokens":69,"server_tool_use":{"web_search_requests":0,"web_fetch_requests":0},"service_tier":"standard","cache_creation":{"ephemeral_1h_input_tokens":0,"ephemeral_5m_input_tokens":3603},"inference_geo":"","iterations":[],"speed":"standard"}},"requestId":"req_011CZ1DTLFJVo71xZC2C7HHC","type":"assistant","uuid":"1da6cc18-dc56-4b07-a55d-7c7ec3c68593","timestamp":"2026-03-13T14:12:02.412Z","userType":"external","cwd":"/Users/jan/prg/ClusterCockpit/cc-backend","sessionId":"889ef150-c6ca-4f35-81e5-c19dc95fe399","version":"2.1.74","gitBranch":"hotfix","slug":"recursive-giggling-volcano"} +{"parentUuid":"1da6cc18-dc56-4b07-a55d-7c7ec3c68593","isSidechain":false,"type":"progress","data":{"type":"hook_progress","hookEvent":"PostToolUse","hookName":"PostToolUse:Read","command":"callback"},"parentToolUseID":"toolu_016KHumoJ75SUh7X9K1dBwVa","toolUseID":"toolu_016KHumoJ75SUh7X9K1dBwVa","timestamp":"2026-03-13T14:12:02.443Z","uuid":"cd5ff376-d254-40fb-8a96-f6c329a0d77d","userType":"external","cwd":"/Users/jan/prg/ClusterCockpit/cc-backend","sessionId":"889ef150-c6ca-4f35-81e5-c19dc95fe399","version":"2.1.74","gitBranch":"hotfix","slug":"recursive-giggling-volcano"} +{"parentUuid":"1da6cc18-dc56-4b07-a55d-7c7ec3c68593","isSidechain":false,"promptId":"cef5abc9-1504-479e-870d-845cb284bb17","type":"user","message":{"role":"user","content":[{"tool_use_id":"toolu_016KHumoJ75SUh7X9K1dBwVa","type":"tool_result","content":" 1→# Usage Dashboard Query Optimization\n 2→\n 3→## Change 1: Partial indexes for running jobs\n 4→\n 5→- **New `internal/repository/migrations/sqlite3/14_running-partial-indexes.up.sql`** — partial covering indexes `WHERE job_state = 'running'` for user/project/subcluster groupings.

Only running jobs in B-tree (tiny vs millions).\n- **New `internal/repository/migrations/sqlite3/14_running-partial-indexes.down.sql`** — drop them.\n- **`internal/repository/migration.go:30`** — `Version` 13 → 14.\n- **`internal/repository/jobQuery.go:200-202`** — inline literal state value (`fmt.Sprintf(\"job.job_state = '%s'\", singleStat)`) so SQLite matches partial indexes. Safe: values from validated GraphQL enum.\n\n## Change 2: Request-scoped cache for grouped stats (6 SQL → 2)\n\n- **`internal/graph/stats_cache.go`** (new) — define `statsGroupCache` type (wraps `sync.Map`), context key, `getOrCompute` method using `sync.Once` per cache entry.\n- **`cmd/cc-backend/server.go:87-88`** — add `graphQLServer.AroundOperations` middleware to inject empty cache into context per request.\n- **`internal/graph/schema.resolvers.go:671-678`** — in `JobsStatistics`, when `groupBy != nil`: check cache for (filter+groupBy) key → on miss, call `JobsStatsGrouped` with nil sortBy/page (all results), cache them → sort+slice in Go per caller's sortBy/page.\n\n## Change 3: Parallelize histogram queries\n\n- **`internal/repository/stats.go:643-668`** — replace 4 sequential histogram calls in `AddHistograms` with `errgroup.WithContext`.

4 changes are implemented and verified:\n\n1. **Partial indexes** — Migration 14 creates partial covering indexes `WHERE job_state = 'running'` for user/project/subcluster groupings. Version bumped to 14. The `BuildWhereClause` now inlines the literal state value (`job.job_state = 'running'`) so SQLite matches the partial index instead of using a parameterized placeholder.\n\n2. **Request-scoped cache** — `stats_cache.go` provides a `statsGroupCache` injected per GraphQL operation via `AroundOperations` middleware. When the same `(filter, groupBy)` pair is requested multiple times (e.g. topUserJobs, topUserNodes, topUserAccs), the DB query runs only once; sort+page is done in Go.\n\n3. **Parallel histograms** — `AddHistograms` now runs all 4 histogram queries concurrently using `errgroup.WithContext`.\n\n4. **Frontend consolidation** — `UsageDash.svelte` sends 2 GraphQL aliases (allUsers, allProjects) requesting all fields, then derives 6 sorted+sliced top-10 lists client-side via `$derived`."}],"stop_reason":"end_turn","stop_sequence":null,"usage":{"input_tokens":1,"cache_creation_input_tokens":137,"cache_read_input_tokens":92043,"output_tokens":287,"server_tool_use":{"web_search_requests":0,"web_fetch_requests":0},"service_tier":"standard","cache_creation":{"ephemeral_1h_input_tokens":0,"ephemeral_5m_input_tokens":137},"inference_geo":"","iterations":[],"speed":"standard"}},"requestId":"req_011CZ1A7qkB8HuoEk6fsa4Xi","type":"assistant","uuid":"099804b7-9b06-4a50-a6cc-6cfaba7c63c2","timestamp":"2026-03-13T13:28:24.534Z","userType":"external","cwd":"/Users/jan/prg/ClusterCockpit/cc-backend","sessionId":"889ef150-c6ca-4f35-81e5-c19dc95fe399","version":"2.1.74","gitBranch":"hotfix","slug":"recursive-giggling-volcano"}

All values come from either hardcoded constants or validated GraphQL enums\n2. **Mixed parameterization approach** - 5 use parameterized queries (Squirrel with ?), 9 use inlined literals\n3. **Intentional inlining in jobQuery.go:204** - Comment documents this is safe for SQLite partial index optimization\n4. **Consistent \"running\" state usage** - Almost all filters target the hardcoded \"running\" state for specific queries\n5. **One minor issue in job.go:817** - Missing \"job.\" table prefix in UpdateDuration query (though still safe as it's unambiguous)"}],"totalDurationMs":53390,"totalTokens":66263,"totalToolUseCount":17,"usage":{"input_tokens":5,"cache_creation_input_tokens":9264,"cache_read_input_tokens":53822,"output_tokens":3172,"server_tool_use":{"web_search_requests":0,"web_fetch_requests":0},"service_tier":"standard","cache_creation":{"ephemeral_1h_input_tokens":0,"ephemeral_5m_input_tokens":9264},"inference_geo":"","iterations":[],"speed":"standard"}},"sourceToolAssistantUUID":"8cbf0c52-c5b0-4c92-a63e-ba22eb7416fd","userType":"external","cwd":"/Users/jan/prg/ClusterCockpit/cc-backend","sessionId":"889ef150-c6ca-4f35-81e5-c19dc95fe399","version":"2.1.74","gitBranch":"hotfix","slug":"recursive-giggling-volcano"} +{"parentUuid":"eab5e799-0172-4a96-ad80-8a9ebe391648","isSidechain":false,"message":{"model":"claude-opus-4-6","id":"msg_01LunFsBm6KQMnHbRchWL5Qj","type":"message","role":"assistant","content":[{"type":"tool_use","id":"toolu_016KHumoJ75SUh7X9K1dBwVa","name":"Read","input":{"file_path":"/Users/jan/.claude/plans/recursive-giggling-volcano.md"},"caller":{"type":"direct"}}],"stop_reason":"tool_use","stop_sequence":null,"usage":{"input_tokens":1,"cache_creation_input_tokens":3603,"cache_read_input_tokens":96447,"output_tokens":69,"server_tool_use":{"web_search_requests":0,"web_fetch_requests":0},"service_tier":"standard","cache_creation":{"ephemeral_1h_input_tokens":0,"ephemeral_5m_input_tokens":3603},"inference_geo":"","iterations":[],"speed":"standard"}},"requestId":"req_011CZ1DTLFJVo71xZC2C7HHC","type":"assistant","uuid":"1da6cc18-dc56-4b07-a55d-7c7ec3c68593","timestamp":"2026-03-13T14:12:02.412Z","userType":"external","cwd":"/Users/jan/prg/ClusterCockpit/cc-backend","sessionId":"889ef150-c6ca-4f35-81e5-c19dc95fe399","version":"2.1.74","gitBranch":"hotfix","slug":"recursive-giggling-volcano"} +{"parentUuid":"1da6cc18-dc56-4b07-a55d-7c7ec3c68593","isSidechain":false,"type":"progress","data":{"type":"hook_progress","hookEvent":"PostToolUse","hookName":"PostToolUse:Read","command":"callback"},"parentToolUseID":"toolu_016KHumoJ75SUh7X9K1dBwVa","toolUseID":"toolu_016KHumoJ75SUh7X9K1dBwVa","timestamp":"2026-03-13T14:12:02.443Z","uuid":"cd5ff376-d254-40fb-8a96-f6c329a0d77d","userType":"external","cwd":"/Users/jan/prg/ClusterCockpit/cc-backend","sessionId":"889ef150-c6ca-4f35-81e5-c19dc95fe399","version":"2.1.74","gitBranch":"hotfix","slug":"recursive-giggling-volcano"} +{"parentUuid":"1da6cc18-dc56-4b07-a55d-7c7ec3c68593","isSidechain":false,"promptId":"cef5abc9-1504-479e-870d-845cb284bb17","type":"user","message":{"role":"user","content":[{"tool_use_id":"toolu_016KHumoJ75SUh7X9K1dBwVa","type":"tool_result","content":" 1→# Usage Dashboard Query Optimization\n 2→\n 3→## Change 1: Partial indexes for running jobs\n 4→\n 5→- **New `internal/repository/migrations/sqlite3/14_running-partial-indexes.up.sql`** — partial covering indexes `WHERE job_state = 'running'` for user/project/subcluster groupings.

The `BuildWhereClause` now inlines the literal state value (`job.job_state = 'running'`) so SQLite matches the partial index instead of using a parameterized placeholder.\n\n2. **Request-scoped cache** — `stats_cache.go` provides a `statsGroupCache` injected per GraphQL operation via `AroundOperations` middleware. When the same `(filter, groupBy)` pair is requested multiple times (e.g. topUserJobs, topUserNodes, topUserAccs), the DB query runs only once; sort+page is done in Go.\n\n3. **Parallel histograms** — `AddHistograms` now runs all 4 histogram queries concurrently using `errgroup.WithContext`.\n\n4. **Frontend consolidation** — `UsageDash.svelte` sends 2 GraphQL aliases (allUsers, allProjects)

All values come from either hardcoded constants or validated GraphQL enums\n2. **Mixed parameterization approach** - 5 use parameterized queries (Squirrel with ?), 9 use inlined literals\n3. **Intentional inlining in jobQuery.go:204** - Comment documents this is safe for SQLite partial index optimization\n4. **Consistent \"running\" state usage** - Almost all filters target the hardcoded \"running\" state for specific queries\n5. **One minor issue in job.go:817** - Missing \"job.\" table prefix in UpdateDuration query (though still safe as it's unambiguous)"}],"totalDurationMs":53390,"totalTokens":66263,"totalToolUseCount":17,"usage":{"input_tokens":5,"cache_creation_input_tokens":9264,"cache_read_input_tokens":53822,"output_tokens":3172,"server_tool_use":{"web_search_requests":0,"web_fetch_requests":0},"service_tier":"standard","cache_creation":{"ephemeral_1h_input_tokens":0,"ephemeral_5m_input_tokens":9264},"inference_geo":"","iterations":[],"speed":"standard"}},"sourceToolAssistantUUID":"8cbf0c52-c5b0-4c92-a63e-ba22eb7416fd","userType":"external","cwd":"/Users/jan/prg/ClusterCockpit/cc-backend","sessionId":"889ef150-c6ca-4f35-81e5-c19dc95fe399","version":"2.1.74","gitBranch":"hotfix","slug":"recursive-giggling-volcano"} +{"parentUuid":"eab5e799-0172-4a96-ad80-8a9ebe391648","isSidechain":false,"message":{"model":"claude-opus-4-6","id":"msg_01LunFsBm6KQMnHbRchWL5Qj","type":"message","role":"assistant","content":[{"type":"tool_use","id":"toolu_016KHumoJ75SUh7X9K1dBwVa","name":"Read","input":{"file_path":"/Users/jan/.claude/plans/recursive-giggling-volcano.md"},"caller":{"type":"direct"}}],"stop_reason":"tool_use","stop_sequence":null,"usage":{"input_tokens":1,"cache_creation_input_tokens":3603,"cache_read_input_tokens":96447,"output_tokens":69,"server_tool_use":{"web_search_requests":0,"web_fetch_requests":0},"service_tier":"standard","cache_creation":{"ephemeral_1h_input_tokens":0,"ephemeral_5m_input_tokens":3603},"inference_geo":"","iterations":[],"speed":"standard"}},"requestId":"req_011CZ1DTLFJVo71xZC2C7HHC","type":"assistant","uuid":"1da6cc18-dc56-4b07-a55d-7c7ec3c68593","timestamp":"2026-03-13T14:12:02.412Z","userType":"external","cwd":"/Users/jan/prg/ClusterCockpit/cc-backend","sessionId":"889ef150-c6ca-4f35-81e5-c19dc95fe399","version":"2.1.74","gitBranch":"hotfix","slug":"recursive-giggling-volcano"} +{"parentUuid":"1da6cc18-dc56-4b07-a55d-7c7ec3c68593","isSidechain":false,"type":"progress","data":{"type":"hook_progress","hookEvent":"PostToolUse","hookName":"PostToolUse:Read","command":"callback"},"parentToolUseID":"toolu_016KHumoJ75SUh7X9K1dBwVa","toolUseID":"toolu_016KHumoJ75SUh7X9K1dBwVa","timestamp":"2026-03-13T14:12:02.443Z","uuid":"cd5ff376-d254-40fb-8a96-f6c329a0d77d","userType":"external","cwd":"/Users/jan/prg/ClusterCockpit/cc-backend","sessionId":"889ef150-c6ca-4f35-81e5-c19dc95fe399","version":"2.1.74","gitBranch":"hotfix","slug":"recursive-giggling-volcano"} +{"parentUuid":"1da6cc18-dc56-4b07-a55d-7c7ec3c68593","isSidechain":false,"promptId":"cef5abc9-1504-479e-870d-845cb284bb17","type":"user","message":{"role":"user","content":[{"tool_use_id":"toolu_016KHumoJ75SUh7X9K1dBwVa","type":"tool_result","content":" 1→# Usage Dashboard Query Optimization\n 2→\n 3→## Change 1: Partial indexes for running jobs\n 4→\n 5→- **New `internal/repository/migrations/sqlite3/14_running-partial-indexes.up.sql`** — partial covering indexes `WHERE job_state = 'running'` for user/project/subcluster groupings.

1→# `cc-backend` version 1.5.1\n 2→\n 3→Supports job archive version 3 and database version 12.\n 4→\n 5→This is a bugfix release of `cc-backend`, the API backend and frontend\n 6→implementation of ClusterCockpit.\n 7→For release specific notes visit the [ClusterCockpit Documentation](https://clusterockpit.org/docs/release/).\n 8→\n 9→## Changes in 1.5.1\n 10→\n 11→### Database\n 12→\n 13→- **New migration (version 12)**: Added covering index for stats queries for significantly improved query performance\n 14→- **New migration (version 11)**: Optimized database index count for better performance\n 15→- **Migration 9 fix**: Removed redundant indices from migration 9 that are superseded by migration 11\n 16→- **Optional DB optimization flag**: Added `-optimize-db` CLI flag to run `ANALYZE` on demand; removed automatic ANALYZE on startup\n 17→- **Selective stats queries**: Stats queries are now selective, reducing unnecessary computation\n 18→- **User list paging**: Added paging support to the user list for better scalability\n 19→- **SQLite configuration hardening**: Sanitized SQLite configuration with new configurable options; fixes large heap allocations in the SQLite driver\n 20→- **Query cancellation**: Long-running database queries can now be cancelled\n 21→- **Resource leak fix**: Added missing `defer Close()` calls for all query result sets\n 22→\n 23→### Bug fixes\n 24→\n 25→- **Segfault when taggers misconfigured**: Fixed crash when `enable-job-taggers` is set but tagger rule directories are missing\n 26→- **GroupBy stats query complexity**: Reduced complexity for `groupBy` statistics queries\n 27→- **Ranged filter conditions**: Fixed GT and LT conditions in ranged filters\n 28→- **Energy filter preset**: Reduced energy filter preset to a more practical default\n 29→- **JSON validity check**: Fixed wrong field being checked for JSON validity\n 30→- **Tagger float rounding**: Fixed rounding of floats in tagger messages\n 31→- **Node view null safety**: Added null-safe checks in node view to prevent runtime errors\n 32→- **Public dashboard null safety**: Added null-safe checks in the public dashboard to prevent runtime errors\n 33→\n 34→### Frontend\n 35→\n 36→- **Bumped patch versions**: Updated frontend dependencies to latest patch versions\n 37→\n 38→### Documentation\n 39→\n 40→- **New DB config options**: Added new database configuration options to README\n 41→\n 42→---\n 43→\n 44→*The sections below document all features and changes introduced in the 1.5.0 major release, which 1.5.1 is based on.*\n 45→\n 46→## Breaking changes\n 47→\n 48→### Configuration changes\n 49→\n 50→- **JSON attribute naming**: All JSON configuration attributes now use `kebab-case`\n 51→ style consistently (e.g., `api-allowed-ips` instead of `apiAllowedIPs`).\n 52→ Update your `config.json` accordingly.\n 53→- **Removed `disable-archive` option**: This obsolete configuration option has been removed.\n 54→- **Removed `clusters` config section**: The separate clusters configuration section\n 55→ has been removed. Cluster information is now derived from the job archive.\n 56→- **`apiAllowedIPs` is now optional**: If not specified, defaults to not\n 57→ restricted.\n 58→\n 59→### Architecture changes\n 60→\n 61→- **Web framework replaced**: Migrated from `gorilla/mux` to `chi` as the HTTP\n 62→ router. This should be transparent to users but affects how middleware and\n 63→ routes are composed. A proper 404 handler is now in place.\n 64→- **MetricStore moved**: The `metricstore` package has been moved from `internal/`\n 65→ to `pkg/` as it is now part of the public API.\n 66→- **MySQL/MariaDB support removed**: Only SQLite is now supported as the database backend.\n 67→- **Archive to Cleanup renaming**: Archive-related functions have been refactored\n 68→ and renamed to \"Cleanup\" for clarity.\n 69→- **`minRunningFor` filter removed**: This undocumented filter has been removed\n 70→ from the API and frontend.\n 71→\n 72→### Dependency changes\n 73→\n 74→- **cc-lib v2.8.0**: Switched to cc-lib version 2 with updated APIs\n 75→- **cclib NATS client**: Now using the cclib NATS client implementation\n 76→- Removed obsolete `util.Float` usage from cclib\n 77→\n 78→## Major new features\n 79→\n 80→### NATS API Integration\n 81→\n 82→- **Real-time job events**: Subscribe to job start/stop events via NATS\n 83→- **Node state updates**: Receive real-time node state changes via NATS\n 84→- **Configurable subjects**: NATS API subjects are now configurable via `api-subjects`\n 85→- **Deadlock fixes**: Improved NATS client stability and graceful shutdown\n 86→\n 87→### Public Dashboard\n 88→\n 89→- **Public-facing interface**: New public dashboard route for external users\n 90→- **DoubleMetricPlot component**: New visualization component for comparing metrics\n 91→- **Improved layout**: Reviewed and optimized dashboard layouts for better readability\n 92→\n 93→### Enhanced Node Management\n 94→\n 95→- **Node state tracking**: New node table in database with timestamp tracking\n 96→- **Node state filtering**: Filter jobs by node state in systems view\n 97→- **Node list enhancements**: Improved paging, filtering, and continuous scroll support\n 98→- **Nodestate retention and archiving**: Node state data is now subject to configurable\n 99→ retention policies and can be archived to Parquet format for long-term storage\n 100→- **Faulty node metric tracking**: Faulty node state metric lists are persisted to the database\n 101→\n 102→### Health Monitoring\n 103→\n 104→- **Health status dashboard**: New dedicated \"Health\" tab in the status details view\n 105→ showing per-node metric health across the cluster\n 106→- **CCMS health check**: Support for querying health status of external\n 107→ cc-metric-store (CCMS) instances via the API\n 108→- **GraphQL health endpoints**: New GraphQL queries and resolvers for health data\n 109→- **Cluster/subcluster filter**: Filter health status view by cluster or

\"Health\" tab in the status details view\n showing per-node metric health across the cluster\n- **CCMS health check**: Support for querying health status of external\n cc-metric-store (CCMS) instances via the API\n- **GraphQL health endpoints**: New GraphQL queries and resolvers for health data\n- **Cluster/subcluster filter**: Filter health status view by cluster or subcluster\n\n### Log Viewer\n\n- **Web-based log viewer**: New log viewer page in the admin interface for inspecting\n backend log output directly from the browser without shell access\n- **Accessible from header**: Quick access link from the navigation header\n\n### MetricStore Improvements\n\n- **Memory tracking worker**: New worker for CCMS memory usage tracking\n- **Dynamic retention**: Support for job specific

classification**: Automatic detection of pathological jobs\n- **omit-tagged**: Option to exclude tagged jobs from retention/cleanup operations (`none`, `all`, or `user`)\n- **Admin UI trigger**: Taggers can be run on-demand from the admin web interface\n without restarting the backend\n\n### Archive Backends\n\n- **Parquet archive format**: New Parquet file format for job archiving, providing\n columnar storage with efficient compression for analytical workloads\n- **S3 backend**: Full support for S3-compatible object storage\n- **SQLite backend**: Full support for SQLite backend using blobs\n- **Performance improvements**: Fixed performance bugs in archive backends\n- **Better error handling**: Improved error messages and fallback handling\n- **Zstd compression**: Parquet writers use zstd compression for better\n compression ratios compared to the previous snappy default\n- **Optimized sort order**: Job and nodestate Parquet files are sorted by\n cluster, subcluster, and start time for efficient range queries\n\n### Unified Archive Retention and Format Conversion\n\n- **Uniform retention policy**: Job archive retention now supports both JSON and\n Parquet as target formats under a single, consistent policy configuration\n- **Archive manager tool**: The `tools/archive-manager` utility now supports\n format conversion between JSON and Parquet job archives\n- **Parquet reader**: Full Parquet archive reader implementation for reading back\n archived job data\n\n## New features and improvements\n\n### Frontend\n\n- **Loading indicators**: Added
