Logs show \"database is locked\" errors and LDAP sync failures (`UNIQUE constraint failed: hpc_user.username`) shortly before the crash.\n\n**Root cause:** A burst of concurrent DB writers (NATS job start/stop, node state updates, LDAP sync, scheduled tasks) overwhelm SQLite's 5-second busy_timeout. Failed operations and blocked goroutines accumulate, consuming memory until OOM.\n\nThe cascade: burst of job events → DB contention → `SQLITE_BUSY` after 5s → error paths spawn retries/new goroutines → goroutine accumulation → OOM.\n\n---\n\n## Fix 1: Increase busy_timeout (contention relief)\n\n**File:** `internal/repository/dbConnection.go:73`\n\nChange `_busy_timeout` from `5000` to `60000` (60 seconds). Also make it configurable:\n\n**File:** `internal/repository/config.go` — add `BusyTimeoutMs int` field, default 60000.\n\n**File:** `internal/repository/dbConnection.go:73` — use `repoConfig.BusyTimeoutMs` instead of hardcoded value.\n\n**File:** `pkg/archive/sqliteBackend.go:105` — also change hardcoded `busy_timeout=5000` to `busy_timeout=60000`.\n\nWith 60s timeout, SQLite retries internally using its backoff mechanism rather than failing fast. This prevents the \"database is locked\" error cascade.\n\n---\n\n## Fix 2: Batch Node State Updates in a Transaction\n\nCurrently each node state update is a separate SELECT + INSERT (2 DB round-trips per node). A message with 1000 nodes = 2000+ individual DB operations, each acquiring/releasing the write lock.\n\n**File:** `internal/repository/node.go` — add `BatchUpdateNodeStates` method:\n- Accept a slice of `(hostname, cluster, nodeState)` tuples\n- Begin transaction\n- For each node: lookup ID (or insert node), then insert state — all within the same transaction\n- Commit once\n\n**File:** `internal/api/nats.go:348-364` (`processNodestateEvent`) — build slice of updates, call `BatchUpdateNodeStates` instead of per-node `UpdateNodeState`.\n\n**File:** `internal/api/node.go:119-142` (`updateNodeStates`) — same change for the REST path. Note: the REST handler also does health checks per node before DB inserts, so batch only the DB part (the loop at lines 119-142).\n\nKeep the existing `UpdateNodeState` method for single-node use cases.\n\n---\n\n## Fix 3: Fix LDAP Sync Race Condition\n\nThe LDAP sync fails when a user is concurrently created by a login. The error is benign but causes `Sync()` to return early (line 215: `return err`), abandoning remaining users.\n\n**File:** `internal/repository/user.go` — add `AddUserIfNotExists` method using `INSERT OR IGNORE`:\n```go\nfunc (r *UserRepository) AddUserIfNotExists(user *schema.User) error {\n rolesJson, _ := json.Marshal(user.Roles)\n projectsJson, _ := json.Marshal(user.Projects)\n cols := \"username, name, roles, projects, ldap\"\n _, err := r.DB.Exec(\n `INSERT OR IGNORE INTO hpc_user (` + cols + `) VALUES (?, ?, ?, ?, ?)`,\n user.Username, user.Name, string(rolesJson), string(projectsJson), int(user.AuthSource))\n return err\n}\n```\n\n**File:** `internal/auth/ldap.go:213` — change `ur.AddUser(user)` to `ur.AddUserIfNotExists(user)`.\n\nNote: `AddUserIfNotExists` intentionally skips the deprecated default metrics config insertion that `AddUser` does — LDAP-synced users don't need it, and it adds unnecessary DB writes.\n\n---\n\n## Fix 4: Add Semaphore for NATS Handlers\n\nWithout rate limiting, blocked NATS handlers cause unbounded goroutine accumulation.\n\n**File:** `internal/api/nats.go` — add semaphores to `NatsAPI` struct:\n```go\ntype NatsAPI struct {\n JobRepository *repository.JobRepository\n RepositoryMutex sync.Mutex\n jobSem chan struct{}\n nodeSem chan struct{}\n}\n```\n\nInitialize in `NewNatsAPI`: `jobSem: make(chan struct{}, 8)`, `nodeSem: make(chan struct{}, 2)`.\n\nAdd acquire/release in `handleJobEvent` and `handleNodeState`:\n```go\napi.jobSem <- struct{}{}\ndefer func() { <-api.jobSem }()\n```\n\nThis caps concurrent NATS processing at 8 job events + 2 node state updates, preventing goroutine pile-up.\n\n---\n\n## Fix 5: Wrap SyncJobs in a Transaction\n\n**File:** `internal/repository/jobCreate.go:72-126` (`SyncJobs`)\n\nCurrently does SELECT + INSERT...SELECT + DELETE as 3 separate operations. Wrap in a DB transaction:\n- `tx, err := r.DB.Beginx()`\n- Run all three operations on `tx`\n- `tx.Commit()`\n- Do the read-only ID resolution outside the transaction\n\nThis reduces lock acquisitions from 3 to 1 and ensures atomicity.\n\n---\n\n## Implementation Order\n\n1. **Fix 1** (busy_timeout) — quick config change, biggest immediate impact\n2. **Fix 3** (LDAP sync) — eliminates error spam, trivial change\n3. **Fix 2** (batch node states) — biggest contention reduction\n4. **Fix 5** (SyncJobs transaction) — safety + minor contention reduction\n5. **Fix 4** (NATS semaphore) — defense in depth against goroutine accumulation\n\n---\n\n## Verification\n\n1. After Fix 1: Check logs for \"database is locked\" — should be gone or very rare.\n2. After Fix 2: check `Timer updateNodeStates, SQLite Inserts` log line — should be much faster.\n3. After Fix 3: check logs for \"UNIQUE constraint failed\" — should be gone.\n4. Run `go test ./internal/repository/... ./internal/api/... ./internal/auth/...` after all changes.\n5.

Now I have enough information to provide a comprehensive analysis. Let me compile my findings:\n\n## DB Write Patterns Analysis - ClusterCockpit cc-backend\n\nBased on my thorough exploration of the codebase, I've identified several DB write patterns and opportunities for transaction-based optimization. Here's my detailed analysis:\n\n---\n\n## 1. TAG OPERATIONS - HIGH TRANSACTION OPPORTUNITY\n\n### Pattern: AddTagOrCreate (Internal/repository/tags.go:424)\nWhen adding tags to a job with multiple tags, each tag operation is **separate and non-transactional**:\n\n```\nstartJob() → for each tag {\n → TagID lookup (SELECT)\n → CreateTag (INSERT) if missing\n → AddTag (INSERT into jobtag)\n → GetTags (SELECT)\n → archive.UpdateTags() (file write)\n}\n```\n\n**Current Issues:**\n- **Line 760-777** in `/internal/api/job.go`: When startJob is called with `req.Tags`, each tag is added individually via `AddTagOrCreate()` inside a loop\n- **Line 570-583** in `/internal/api/job.go`: tagJob endpoint adds multiple tags one-by-one with individual archive updates\n- **Lines 165-210** in `/internal/graph/schema.resolvers.go`: GraphQL AddTagsToJob loops through tag IDs, calling `AddTag()` for each without batching\n\n**Batch Potential:** ⭐⭐⭐⭐⭐ **HIGHEST**\n- A job with 5 tags = 5 separate transactions (INSERT + SELECT + archive write)\n- Could be batched into single transaction: 1 INSERT many jobtag + 1 archive write\n\n### Key File: `/Users/jan/prg/ClusterCockpit/cc-backend/internal/repository/tags.go`\n\n**addJobTag() helper (line 398):** Performs 3 operations per tag:\n1. INSERT into jobtag\n2. SELECT tags\n3. archive.UpdateTags() (file I/O)\n\n**AddTagOrCreate() (line 424):** Chains multiple operations:\n1. TagID lookup\n2. CreateTag if missing (conditional INSERT)\n3. AddTag (calls addJobTag, which does 3 more ops)\n\n---\n\n## 2. JOB ARCHIVING WRITES - MODERATE TRANSACTION OPPORTUNITY\n\n### Pattern: Archiving Workflow (archiveWorker in /internal/archiver/archiveWorker.go)\n\nWhen a job is archived, **3-4 separate UPDATE statements** execute sequentially:\n\n```\narchivingWorker() → for job in archiveChannel {\n → FetchMetadata (SELECT)\n → ArchiveJob() (file writes + calculations)\n → UpdateFootprint (UPDATE)\n → UpdateEnergy (UPDATE) \n → MarkArchived (UPDATE)\n → Execute(stmt) (single UPDATE with 3 SET clauses)\n → CallJobStopHooks()\n}\n```\n\n**Current Issues:**\n- **Lines 145-159** in `/internal/archiver/archiveWorker.go`: Three separate `.Set()` calls chained together but executed as ONE statement via `jobRepo.Execute(stmt)`\n- Actually **GOOD**: The code chains multiple SET operations into a single UPDATE via Squirrel builder pattern\n- However, the statement is still a single UPDATE - could be a transaction for safety\n\n**Transaction Benefit:** ⭐⭐⭐ **MODERATE**\n- Currently chains SETs into one UPDATE (good)\n- Could add transaction wrapper for atomicity guarantee\n- Already uses statement builder pattern to combine updates\n\n### Key Files:\n- `/Users/jan/prg/ClusterCockpit/cc-backend/internal/archiver/archiveWorker.go:145-163`\n- `/Users/jan/prg/ClusterCockpit/cc-backend/internal/repository/job.go:908-999` (UpdateEnergy, UpdateFootprint, MarkArchived, Execute)\n\n---\n\n## 3. JOB IMPORT/RESTORE - HIGH TRANSACTION OPPORTUNITY\n\n### Pattern: HandleImportFlag (internal/importer/handleImport.go:38)\n\nImports job metadata + tags without batching:\n\n```\nHandleImportFlag(flag) → for each job in flag {\n → Read JSON files\n → archive.ImportJob() (file write)\n → InsertJobDirect (INSERT)\n → for each tag in job.Tags {\n → ImportTag() (SELECT + INSERT per tag)\n }\n}\n```\n\n**Current Issues:**\n- **Lines 105-116** in `/internal/importer/handleImport.go`: \n - 1 job INSERT per job\n - N tag operations (SELECT + INSERT) per job\n - No transaction wrapping job + all its tags\n \n**Batch Potential:** ⭐⭐⭐⭐⭐ **HIGHEST**\n- If importing 100 jobs with 3 tags each = 100 INSERTs + 300 tag lookups/inserts\n- Could batch into transaction: INSERT 100 jobs + 300 tag associations in single txn\n\n### Key File: `/Users/jan/prg/ClusterCockpit/cc-backend/internal/importer/handleImport.go:111-116`\n\n---\n\n## 4. JOB CACHE TO MAIN TABLE TRANSFER - IDENTIFIED ISSUE\n\n### Pattern: TransferCachedJobToMain (internal/repository/jobCreate.go:143)\n\n**EXACT ISSUE YOU MENTIONED:**\n\n```go\n// TransferCachedJobToMain - Lines 143-162\nfunc (r *JobRepository) TransferCachedJobToMain(cacheID int64) (int64, error) {\n res, err := r.DB.Exec(\n \"INSERT INTO job ... SELECT ... FROM job_cache WHERE id = ?\", cacheID)\n if err != nil { return 0, ... }\n \n newID, err := res.LastInsertId()\n if err != nil { return 0, ... }\n \n _, err = r.DB.Exec(\"DELETE FROM job_cache WHERE id = ?\", cacheID) // SEPARATE OPERATION\n if err != nil { return 0, ... }\n \n return newID, nil\n}\n```\n\n**Issue:** ⚠️ **TWO SEPARATE EXEC CALLS**\n- Line 144-146: INSERT\n- Line 156: DELETE\n- No transaction wrapping both operations\n- **Risk:** If DELETE fails, job orphaned in main table and cache\n\n**Transaction Fix:** Wrap both operations in `tx.Beginx()` / `tx.Commit()`\n\n### Key File: `/Users/jan/prg/ClusterCockpit/cc-backend/internal/repository/jobCreate.go:143-162`\n\n---\n\n## 5. JOB STOP WORKFLOW - MILD CONSOLIDATION OPPORTUNITY\n\n### Pattern: stopJobByRequest (internal/api/job.go:805)\n\nCalls `checkAndHandleStopJob()` which likely:\n1. Updates job state (Stop)\n2. Transfers from cache to main table (INSERT + DELETE as shown above)\n3. Triggers archiving\n\n**Issue:** Multiple separate repository calls that could be transactional\n\n### Key Files:\n- `/Users/jan/prg/ClusterCockpit/cc-backend/internal/api/job.go:805-835`\n- The actual logic is in `checkAndHandleStopJob()` - would need to read that\n\n---\n\n## 6. TAG REMOVAL - DISTRIBUTED WRITES\n\n### Pattern: RemoveTagByID (internal/repository/tags.go:216)\n\n```go\n// RemoveTagByID - Lines 216-244\nfunc (r *JobRepository) RemoveTagByID(tagID int64) error {\n jobIds, err := r.FindJobIdsByTag(tagID) // SELECT all job IDs\n \n qJobTag := sq.Delete(\"jobtag\").Where(\"jobtag.tag_id = ?\", tagID)\n if _, err := qJobTag.RunWith(r.stmtCache).Exec(); err != nil { ... }\n \n qTag := sq.Delete(\"tag\").Where(\"tag.id = ?\", tagID)\n if _, err := qTag.RunWith(r.stmtCache).Exec(); err != nil { ... }\n \n go r.removeTagFromArchiveJobs(jobIds) // ASYNC goroutine\n \n return nil\n}\n```\n\n**Issues:**\n- **2 separate DELETE statements** (jobtag, then tag)\n- Could be 1 transaction\n- Archive updates run **asynchronously in goroutine** (line 241)\n- **Lines 183-199** show async archive updates without error handling\n\n**Transaction Opportunity:** ⭐⭐⭐ **MODERATE**\n- Can wrap 2 DELETEs in single transaction\n\n### Key Files:\n- `/Users/jan/prg/ClusterCockpit/cc-backend/internal/repository/tags.go:216-244`\n- `/Users/jan/prg/ClusterCockpit/cc-backend/internal/repository/tags.go:183-199`\n\n---\n\n## 7. GRAPHQL TAG MUTATIONS - LOOP-BASED WRITES\n\n### Pattern: AddTagsToJob, RemoveTagsFromJob (internal/graph/schema.resolvers.go:166, 213)\n\n**Lines 179-207** and **Lines 226-255**:\n```go\nfor _, tagID := range tagIds {\n // Lookup tag\n _, _, tscope, exists := r.Repo.TagInfo(tid)\n // Authorization check\n // Add/Remove\n if tags, err = r.Repo.AddTag(...); err != nil { ... }\n}\n```\n\n**Issue:**\n- **Loop per tag** with individual `AddTag()` or `RemoveTag()` calls\n- 5 tags = 5 separate database transactions with archive updates\n- Could batch into single transaction\n\n**Batch Potential:** ⭐⭐⭐⭐ **HIGH**\n\n### Key File: `/Users/jan/prg/ClusterCockpit/cc-backend/internal/graph/schema.resolvers.go:165-210, 212-258`\n\n---\n\n## 8. NATS API - SEMAPHORE-PROTECTED WRITES\n\n### Pattern: NATS Job/Node event handlers (internal/api/nats.go)\n\nUses semaphores to limit concurrency:\n```go\ntype NatsAPI struct {\n jobSem chan struct{} // capacity 8\n nodeSem chan struct{} // capacity 2\n}\n\nfunc (api *NatsAPI) handleJobEvent(...) {\n api.jobSem <- struct{}{} // acquire semaphore\n defer func() { <-api.jobSem }() // release\n // ... process job (same write patterns as REST)\n}\n```\n\n**No Issues:** Semaphores are for concurrency control, not transactional. Underlying writes are same as REST API (non-transactional tag adds).\n\n### Key File: `/Users/jan/prg/ClusterCockpit/cc-backend/internal/api/nats.go:62-80, 147-148`\n\n---\n\n## 9. STATISTICS/ENERGY FOOTPRINT UPDATES - AGGREGATION-ONLY\n\n### Pattern: Stats queries (internal/repository/stats.go)\n\nAll **READ-ONLY** SELECT with aggregations.

Now I have enough information to provide a comprehensive analysis. Let me compile my findings:\n\n## DB Write Patterns Analysis - ClusterCockpit cc-backend\n\nBased on my thorough exploration of the codebase, I've identified several DB write patterns and opportunities for transaction-based optimization. Here's my detailed analysis:\n\n---\n\n## 1. TAG OPERATIONS - HIGH TRANSACTION OPPORTUNITY\n\n### Pattern: AddTagOrCreate (Internal/repository/tags.go:424)\nWhen adding tags to a job with multiple tags, each tag operation is **separate and non-transactional**:\n\n```\nstartJob() → for each tag {\n → TagID lookup (SELECT)\n → CreateTag (INSERT) if missing\n → AddTag (INSERT into jobtag)\n → GetTags (SELECT)\n → archive.UpdateTags() (file write)\n}\n```\n\n**Current Issues:**\n- **Line 760-777** in `/internal/api/job.go`: When startJob is called with `req.Tags`, each tag is added individually via `AddTagOrCreate()` inside a loop\n- **Line 570-583** in `/internal/api/job.go`: tagJob endpoint adds multiple tags one-by-one with individual archive updates\n- **Lines 165-210** in `/internal/graph/schema.resolvers.go`: GraphQL AddTagsToJob loops through tag IDs, calling `AddTag()` for each without batching\n\n**Batch Potential:** ⭐⭐⭐⭐⭐ **HIGHEST**\n- A job with 5 tags = 5 separate transactions (INSERT + SELECT + archive write)\n- Could be batched into single transaction: 1 INSERT many jobtag + 1 archive write\n\n### Key File: `/Users/jan/prg/ClusterCockpit/cc-backend/internal/repository/tags.go`\n\n**addJobTag() helper (line 398):** Performs 3 operations per tag:\n1. INSERT into jobtag\n2. SELECT tags\n3. archive.UpdateTags() (file I/O)\n\n**AddTagOrCreate() (line 424):** Chains multiple operations:\n1. TagID lookup\n2. CreateTag if missing (conditional INSERT)\n3. AddTag (calls addJobTag, which does 3 more ops)\n\n---\n\n## 2. JOB ARCHIVING WRITES - MODERATE TRANSACTION OPPORTUNITY\n\n### Pattern: Archiving Workflow (archiveWorker in /internal/archiver/archiveWorker.go)\n\nWhen a job is archived, **3-4 separate UPDATE statements** execute sequentially:\n\n```\narchivingWorker() → for job in archiveChannel {\n → FetchMetadata (SELECT)\n → ArchiveJob() (file writes + calculations)\n → UpdateFootprint (UPDATE)\n → UpdateEnergy (UPDATE) \n → MarkArchived (UPDATE)\n → Execute(stmt) (single UPDATE with 3 SET clauses)\n → CallJobStopHooks()\n}\n```\n\n**Current Issues:**\n- **Lines 145-159** in `/internal/archiver/archiveWorker.go`: Three separate `.Set()` calls chained together but executed as ONE statement via `jobRepo.Execute(stmt)`\n- Actually **GOOD**: The code chains multiple SET operations into a single UPDATE via Squirrel builder pattern\n- However, the statement is still a single UPDATE - could be a transaction for safety\n\n**Transaction Benefit:** ⭐⭐⭐ **MODERATE**\n- Currently chains SETs into one UPDATE (good)\n- Could add transaction wrapper for atomicity guarantee\n- Already uses statement builder pattern to combine updates\n\n### Key Files:\n- `/Users/jan/prg/ClusterCockpit/cc-backend/internal/archiver/archiveWorker.go:145-163`\n- `/Users/jan/prg/ClusterCockpit/cc-backend/internal/repository/job.go:908-999` (UpdateEnergy, UpdateFootprint, MarkArchived, Execute)\n\n---\n\n## 3. JOB IMPORT/RESTORE - HIGH TRANSACTION OPPORTUNITY\n\n### Pattern: HandleImportFlag (internal/importer/handleImport.go:38)\n\nImports job metadata + tags without batching:\n\n```\nHandleImportFlag(flag) → for each job in flag {\n → Read JSON files\n → archive.ImportJob() (file write)\n → InsertJobDirect (INSERT)\n → for each tag in job.Tags {\n → ImportTag() (SELECT + INSERT per tag)\n }\n}\n```\n\n**Current Issues:**\n- **Lines 105-116** in `/internal/importer/handleImport.go`: \n - 1 job INSERT per job\n - N tag operations (SELECT + INSERT) per job\n - No transaction wrapping job + all its tags\n \n**Batch Potential:** ⭐⭐⭐⭐⭐ **HIGHEST**\n- If importing 100 jobs with 3 tags each = 100 INSERTs + 300 tag lookups/inserts\n- Could batch into transaction: INSERT 100 jobs + 300 tag associations in single txn\n\n### Key File: `/Users/jan/prg/ClusterCockpit/cc-backend/internal/importer/handleImport.go:111-116`\n\n---\n\n## 4. JOB CACHE TO MAIN TABLE TRANSFER - IDENTIFIED ISSUE\n\n### Pattern: TransferCachedJobToMain (internal/repository/jobCreate.go:143)\n\n**EXACT ISSUE YOU MENTIONED:**\n\n```go\n// TransferCachedJobToMain - Lines 143-162\nfunc (r *JobRepository) TransferCachedJobToMain(cacheID int64) (int64, error) {\n res, err := r.DB.Exec(\n \"INSERT INTO job ... SELECT ... FROM job_cache WHERE id = ?\", cacheID)\n if err != nil { return 0, ... }\n \n newID, err := res.LastInsertId()\n if err != nil { return 0, ... }\n \n _, err = r.DB.Exec(\"DELETE FROM job_cache WHERE id = ?\", cacheID) // SEPARATE OPERATION\n if err != nil { return 0, ... }\n \n return newID, nil\n}\n```\n\n**Issue:** ⚠️ **TWO SEPARATE EXEC CALLS**\n- Line 144-146: INSERT\n- Line 156: DELETE\n- No transaction wrapping both operations\n- **Risk:** If DELETE fails, job orphaned in main table and cache\n\n**Transaction Fix:** Wrap both operations in `tx.Beginx()` / `tx.Commit()`\n\n### Key File: `/Users/jan/prg/ClusterCockpit/cc-backend/internal/repository/jobCreate.go:143-162`\n\n---\n\n## 5. JOB STOP WORKFLOW - MILD CONSOLIDATION OPPORTUNITY\n\n### Pattern: stopJobByRequest (internal/api/job.go:805)\n\nCalls `checkAndHandleStopJob()` which likely:\n1. Updates job state (Stop)\n2. Transfers from cache to main table (INSERT + DELETE as shown above)\n3. Triggers archiving\n\n**Issue:** Multiple separate repository calls that could be transactional\n\n### Key Files:\n- `/Users/jan/prg/ClusterCockpit/cc-backend/internal/api/job.go:805-835`\n- The actual logic is in `checkAndHandleStopJob()` - would need to read that\n\n---\n\n## 6. TAG REMOVAL - DISTRIBUTED WRITES\n\n### Pattern: RemoveTagByID (internal/repository/tags.go:216)\n\n```go\n// RemoveTagByID - Lines 216-244\nfunc (r *JobRepository) RemoveTagByID(tagID int64) error {\n jobIds, err := r.FindJobIdsByTag(tagID) // SELECT all job IDs\n \n qJobTag := sq.Delete(\"jobtag\").Where(\"jobtag.tag_id = ?\", tagID)\n if _, err := qJobTag.RunWith(r.stmtCache).Exec(); err != nil { ... }\n \n qTag := sq.Delete(\"tag\").Where(\"tag.id = ?\", tagID)\n if _, err := qTag.RunWith(r.stmtCache).Exec(); err != nil { ... }\n \n go r.removeTagFromArchiveJobs(jobIds) // ASYNC goroutine\n \n return nil\n}\n```\n\n**Issues:**\n- **2 separate DELETE statements** (jobtag, then tag)\n- Could be 1 transaction\n- Archive updates run **asynchronously in goroutine** (line 241)\n- **Lines 183-199** show async archive updates without error handling\n\n**Transaction Opportunity:** ⭐⭐⭐ **MODERATE**\n- Can wrap 2 DELETEs in single transaction\n\n### Key Files:\n- `/Users/jan/prg/ClusterCockpit/cc-backend/internal/repository/tags.go:216-244`\n- `/Users/jan/prg/ClusterCockpit/cc-backend/internal/repository/tags.go:183-199`\n\n---\n\n## 7. GRAPHQL TAG MUTATIONS - LOOP-BASED WRITES\n\n### Pattern: AddTagsToJob, RemoveTagsFromJob (internal/graph/schema.resolvers.go:166, 213)\n\n**Lines 179-207** and **Lines 226-255**:\n```go\nfor _, tagID := range tagIds {\n // Lookup tag\n _, _, tscope, exists := r.Repo.TagInfo(tid)\n // Authorization check\n // Add/Remove\n if tags, err = r.Repo.AddTag(...); err != nil { ... }\n}\n```\n\n**Issue:**\n- **Loop per tag** with individual `AddTag()` or `RemoveTag()` calls\n- 5 tags = 5 separate database transactions with archive updates\n- Could batch into single transaction\n\n**Batch Potential:** ⭐⭐⭐⭐ **HIGH**\n\n### Key File: `/Users/jan/prg/ClusterCockpit/cc-backend/internal/graph/schema.resolvers.go:165-210, 212-258`\n\n---\n\n## 8. NATS API - SEMAPHORE-PROTECTED WRITES\n\n### Pattern: NATS Job/Node event handlers (internal/api/nats.go)\n\nUses semaphores to limit concurrency:\n```go\ntype NatsAPI struct {\n jobSem chan struct{} // capacity 8\n nodeSem chan struct{} // capacity 2\n}\n\nfunc (api *NatsAPI) handleJobEvent(...) {\n api.jobSem <- struct{}{} // acquire semaphore\n defer func() { <-api.jobSem }() // release\n // ... process job (same write patterns as REST)\n}\n```\n\n**No Issues:** Semaphores are for concurrency control, not transactional. Underlying writes are same as REST API (non-transactional tag adds).\n\n### Key File: `/Users/jan/prg/ClusterCockpit/cc-backend/internal/api/nats.go:62-80, 147-148`\n\n---\n\n## 9. STATISTICS/ENERGY FOOTPRINT UPDATES - AGGREGATION-ONLY\n\n### Pattern: Stats queries (internal/repository/stats.go)\n\nAll **READ-ONLY** SELECT with aggregations. No write batching opportunities.\n\nKey observation: Post-archiving stats updates are computed by `UpdateFootprint()` and `UpdateEnergy()` which are already in a single UPDATE statement (item #2).\n\n---\n\n## TRANSACTION SUPPORT STATUS\n\n**Good news:** The codebase **already has transaction support**:\n\n### Available Transaction API (internal/repository/transaction.go):\n```go\ntype Transaction struct { tx *sqlx.Tx }\n\nfunc (r *JobRepository) TransactionInit() (*Transaction, error)\nfunc (t *Transaction) Commit() error\nfunc (t *Transaction) Rollback() error\nfunc (r *JobRepository) TransactionAddNamed(t *Transaction, query string, args ...any) (int64, error)\nfunc (r *JobRepository) TransactionAdd(t *Transaction, query string, args ...any) (int64, error)\n```\n\n**Currently used in:** `/internal/repository/jobCreate.go:96-120` (SyncJobs function uses `tx.Beginx()`)\n\n**Not used in:** Tag operations, individual archiving, import loops\n\n---\n\n## SUMMARY TABLE\n\n| Pattern | Location | Issue | Batch Potential | Transaction Support | Priority |\n|---------|----------|-------|-----------------|---------------------|----------|\n| AddTagOrCreate in loop | api/job.go:760-777, api/job.go:570-583 | 1 txn per tag | ⭐⭐⭐⭐⭐ | Exists | HIGH |\n| ImportTag per tag | importer/handleImport.go:111-116 | 1 txn per tag | ⭐⭐⭐⭐⭐ | Exists | HIGH |\n| TransferCachedJobToMain | repository/jobCreate.go:143-162 | INSERT + DELETE separate | ⭐⭐⭐⭐ | Exists | **CRITICAL** |\n| RemoveTagByID | repository/tags.go:216-244 | 2 separate DELETEs | ⭐⭐⭐ | Exists | MEDIUM |\n| GraphQL AddTagsToJob | graph/schema.resolvers.go:179-207 | 1 txn per tag | ⭐⭐⭐⭐ | Exists | HIGH |\n| Archiving updates | archiver/archiveWorker.go:145-163 | 3 SETs chained (OK) | ⭐⭐ | Already good | LOW |\n| Job stats queries | repository/stats.go | Read-only aggregations | N/A | N/A | N/A |\n\n---\n\n## RECOMMENDATIONS\n\n1. **CRITICAL**: Fix `TransferCachedJobToMain()` - wrap INSERT + DELETE in transaction\n2. **HIGH**: Batch tag operations in `tagJob()` and `AddTagsToJob()` - add `BatchAddTags()` method\n3. **HIGH**: Batch import tag operations - wrap job insert + all tags in single transaction\n4. **MEDIUM**: Consolidate `RemoveTagByID()` - use single transaction for both DELETEs\n5. **MEDIUM**: Add async tag removal with error handling - current goroutine silently fails\n\n---\n\nThese patterns show that while transaction support exists, it's **underutilized** in high-frequency write paths, particularly around tag management where multiple individual operations could be safely batched."}],"totalDurationMs":64839,"totalTokens":81850,"totalToolUseCount":29,"usage":{"input_tokens":5,"cache_creation_input_tokens":1906,"cache_read_input_tokens":76371,"output_tokens":3568,"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":1906},"inference_geo":"","iterations":[],"speed":"standard"}},"sourceToolAssistantUUID":"be9edc37-8b94-42c3-a207-56a1de047ced","userType":"external","cwd":"/Users/jan/prg/ClusterCockpit/cc-backend","sessionId":"3a41c7a4-abf8-484b-96ae-ee5618eea5ba","version":"2.1.76","gitBranch":"hotfix","slug":"woolly-wandering-narwhal"}

`/Users/jan/prg/ClusterCockpit/cc-backend/internal/api/nats.go:206`\n - `RepositoryMutex.Lock()` serializes ALL concurrent job starts\n - Limits throughput to single job start at a time\n - Held during duplicate check + tag operations\n - **Impact:** NATS job start concurrency = 1\n\n2. **TransferCachedJobToMain Race Condition** - `/Users/jan/prg/ClusterCockpit/cc-backend/internal/repository/jobCreate.go:143-162`\n - INSERT + DELETE are separate `Exec()` calls\n - No transaction between them\n - If process crashes between INSERT and DELETE, job_cache row orphaned\n - **Impact:** Data loss / inconsistency risk during transfers\n\n3. **Tag Operations Without Transactions** - `/Users/jan/prg/ClusterCockpit/cc-backend/internal/repository/tags.go`\n - `AddTag()`: DB INSERT jobtag + archive.UpdateTags() separate\n - `RemoveTag()`: DB DELETE jobtag + archive.UpdateTags() separate \n - `RemoveTagByID()`: spawns async goroutine for archive (race condition)\n - **Impact:** DB-archive inconsistency if either fails mid-operation\n\n4. **Archiver Multiple Separate Updates** - `/Users/jan/prg/ClusterCockpit/cc-backend/internal/archiver/archiveWorker.go:130,147-155`\n - UpdateMonitoringStatus (line 130) = separate write\n - UpdateFootprint + UpdateEnergy (lines 147-155) = combined in single statement\n - But if footprint fails, energy never updated\n - **Impact:** Incomplete job archiving data\n\n### **HIGH (P1):**\n\n5. **UpdateUser Without Transaction** - `/Users/jan/prg/ClusterCockpit/cc-backend/internal/repository/user.go:206-276`\n - 4 separate UPDATE paths, no transaction\n - If admin modifies role+project, inconsistent state if second fails\n - **Impact:** User permission inconsistencies\n\n6. **AddUser Deprecated Loop** - `/Users/jan/prg/ClusterCockpit/cc-backend/internal/repository/user.go:167-184`\n - Loop with separate INSERT per cluster\n - Code marked DEPRECATED but still runs\n - **Impact:** N separate writes per user creation\n\n7. **HandleImportFlag No Batching** - `/Users/jan/prg/ClusterCockpit/cc-backend/internal/importer/handleImport.go:38-121`\n - Each imported job is individual (no transaction)\n - Loop of InsertJobDirect + ImportTag calls\n - **Impact:** No batch optimization for bulk imports\n\n8. **DeleteJobsBefore Bulk Without Transaction** - `/Users/jan/prg/ClusterCockpit/cc-backend/internal/repository/job.go:399-461`\n - DELETE from job WHERE start_time < ?\n - Potentially thousands of rows, single statement but no transaction\n - If cascades fail, inconsistent state\n - **Impact:** Data integrity during bulk cleanup\n\n9. **UpdateMetadata Split Write** - `/Users/jan/prg/ClusterCockpit/cc-backend/internal/repository/job.go:268-306`\n - DB UPDATE + archive.UpdateMetadata() separate\n - No transaction\n - **Impact:** DB-archive inconsistency on failure\n\n10. **REST API User Updates Serialize** - `/Users/jan/prg/ClusterCockpit/cc-backend/internal/api/user.go:76-128`\n - Each role/project operation is separate REST handler call\n - updateUser() itself calls single repository method per request\n - **Impact:** User sees 4 separate state changes if adding role+project\n\n---\n\n## SUMMARY TABLE - WRITE OPERATIONS BY CONTENTION RISK\n\n| Component | Location | Writes/Batch | Transaction | Frequency | Risk Level |\n|-----------|----------|--------------|-------------|-----------|-----------|\n| Job Start (NATS) | nats.go:206 | 1-2 (job+tags) | **Mutex-only** | Per job start | **CRITICAL** |\n| Job Start (REST) | jobCreate.go | 1-2 (job+tags) | Mutex-only | Per job start | CRITICAL |\n| TransferCachedJobToMain | jobCreate.go:144,156 | 2 (INSERT+DELETE) | **None** | Cache flush | **CRITICAL** |\n| Tag Add/Remove | tags.go | 2 (DB+archive) | None | Per tag op | **HIGH** |\n| User Update | user.go:206 | 4 (separate UPDATEs) | None | Per admin update | **HIGH** |\n| Node State (batch) | node.go:257 | N (batched) | **Transaction** ✓ | Per REST request | LOW |\n| InitDB Import | initDB.go | 100 (batched) | **Transaction** ✓ | Startup | LOW |\n| Job Archive | archiveWorker.go | 3 (separate) | Partial ✗ | Per job archive | **HIGH** |\n\n---\n\n## RECOMMENDATIONS FOR OPTIMIZATION\n\n1. **Replace Mutex with Transactions** for job start operations\n2. **Batch TagOps** into single transaction for add/remove\n3. **Transactionalize** UpdateUser role/project changes\n4. **Wrap Archiver** updates in single transaction\n5. **Add Transactional Batching** to HandleImportFlag\n6. **Fix TransferCachedJobToMain** race by moving to transaction\n7. **Remove Deprecated User Config Loop** in AddUser\n\nAll paths are now documented with specific file paths, line numbers, and actionable issues."},{"type":"text","text":"agentId: ab0b0e624428f5b1f (for resuming to continue this agent's work if needed)\n<usage>total_tokens: 120521\ntool_uses: 32\nduration_ms: 81558</usage>"}]}]},"uuid":"a337a0bd-8ef5-4b12-8203-5819f98796af","timestamp":"2026-03-16T10:20:01.529Z","toolUseResult":{"status":"completed","prompt":"Explore the cc-backend codebase for all database WRITE operations (INSERT, UPDATE, DELETE, Exec, NamedExec) that could cause SQLite write contention.

`/Users/jan/prg/ClusterCockpit/cc-backend/internal/api/nats.go:206`\n - `RepositoryMutex.Lock()` serializes ALL concurrent job starts\n - Limits throughput to single job start at a time\n - Held during duplicate check + tag operations\n - **Impact:** NATS job start concurrency = 1\n\n2. **TransferCachedJobToMain Race Condition** - `/Users/jan/prg/ClusterCockpit/cc-backend/internal/repository/jobCreate.go:143-162`\n - INSERT + DELETE are separate `Exec()` calls\n - No transaction between them\n - If process crashes between INSERT and DELETE, job_cache row orphaned\n - **Impact:** Data loss / inconsistency risk during transfers\n\n3. **Tag Operations Without Transactions** - `/Users/jan/prg/ClusterCockpit/cc-backend/internal/repository/tags.go`\n - `AddTag()`: DB INSERT jobtag + archive.UpdateTags() separate\n - `RemoveTag()`: DB DELETE jobtag + archive.UpdateTags() separate \n - `RemoveTagByID()`: spawns async goroutine for archive (race condition)\n - **Impact:** DB-archive inconsistency if either fails mid-operation\n\n4. **Archiver Multiple Separate Updates** - `/Users/jan/prg/ClusterCockpit/cc-backend/internal/archiver/archiveWorker.go:130,147-155`\n - UpdateMonitoringStatus (line 130) = separate write\n - UpdateFootprint + UpdateEnergy (lines 147-155) = combined in single statement\n - But if footprint fails, energy never updated\n - **Impact:** Incomplete job archiving data\n\n### **HIGH (P1):**\n\n5. **UpdateUser Without Transaction** - `/Users/jan/prg/ClusterCockpit/cc-backend/internal/repository/user.go:206-276`\n - 4 separate UPDATE paths, no transaction\n - If admin modifies role+project, inconsistent state if second fails\n - **Impact:** User permission inconsistencies\n\n6. **AddUser Deprecated Loop** - `/Users/jan/prg/ClusterCockpit/cc-backend/internal/repository/user.go:167-184`\n - Loop with separate INSERT per cluster\n - Code marked DEPRECATED but still runs\n - **Impact:** N separate writes per user creation\n\n7. **HandleImportFlag No Batching** - `/Users/jan/prg/ClusterCockpit/cc-backend/internal/importer/handleImport.go:38-121`\n - Each imported job is individual (no transaction)\n - Loop of InsertJobDirect + ImportTag calls\n - **Impact:** No batch optimization for bulk imports\n\n8. **DeleteJobsBefore Bulk Without Transaction** - `/Users/jan/prg/ClusterCockpit/cc-backend/internal/repository/job.go:399-461`\n - DELETE from job WHERE start_time < ?\n - Potentially thousands of rows, single statement but no transaction\n - If cascades fail, inconsistent state\n - **Impact:** Data integrity during bulk cleanup\n\n9. **UpdateMetadata Split Write** - `/Users/jan/prg/ClusterCockpit/cc-backend/internal/repository/job.go:268-306`\n - DB UPDATE + archive.UpdateMetadata() separate\n - No transaction\n - **Impact:** DB-archive inconsistency on failure\n\n10. **REST API User Updates Serialize** - `/Users/jan/prg/ClusterCockpit/cc-backend/internal/api/user.go:76-128`\n - Each role/project operation is separate REST handler call\n - updateUser() itself calls single repository method per request\n - **Impact:** User sees 4 separate state changes if adding role+project\n\n---\n\n## SUMMARY TABLE - WRITE OPERATIONS BY CONTENTION RISK\n\n| Component | Location | Writes/Batch | Transaction | Frequency | Risk Level |\n|-----------|----------|--------------|-------------|-----------|-----------|\n| Job Start (NATS) | nats.go:206 | 1-2 (job+tags) | **Mutex-only** | Per job start | **CRITICAL** |\n| Job Start (REST) | jobCreate.go | 1-2 (job+tags) | Mutex-only | Per job start | CRITICAL |\n| TransferCachedJobToMain | jobCreate.go:144,156 | 2 (INSERT+DELETE) | **None** | Cache flush | **CRITICAL** |\n| Tag Add/Remove | tags.go | 2 (DB+archive) | None | Per tag op | **HIGH** |\n| User Update | user.go:206 | 4 (separate UPDATEs) | None | Per admin update | **HIGH** |\n| Node State (batch) | node.go:257 | N (batched) | **Transaction** ✓ | Per REST request | LOW |\n| InitDB Import | initDB.go | 100 (batched) | **Transaction** ✓ | Startup | LOW |\n| Job Archive | archiveWorker.go | 3 (separate) | Partial ✗ | Per job archive | **HIGH** |\n\n---\n\n## RECOMMENDATIONS FOR OPTIMIZATION\n\n1. **Replace Mutex with Transactions** for job start operations\n2. **Batch TagOps** into single transaction for add/remove\n3. **Transactionalize** UpdateUser role/project changes\n4. **Wrap Archiver** updates in single transaction\n5. **Add Transactional Batching** to HandleImportFlag\n6. **Fix TransferCachedJobToMain** race by moving to transaction\n7. **Remove Deprecated User Config Loop** in AddUser\n\nAll paths are now documented with specific file paths, line numbers, and actionable issues."}],"totalDurationMs":81558,"totalTokens":120521,"totalToolUseCount":32,"usage":{"input_tokens":4,"cache_creation_input_tokens":3553,"cache_read_input_tokens":111500,"output_tokens":5464,"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":3553},"inference_geo":"","iterations":[],"speed":"standard"}},"sourceToolAssistantUUID":"a93c39ad-d6d5-4a49-a8dd-8b7086258ea9","userType":"external","cwd":"/Users/jan/prg/ClusterCockpit/cc-backend","sessionId":"3a41c7a4-abf8-484b-96ae-ee5618eea5ba","version":"2.1.76","gitBranch":"hotfix","slug":"woolly-wandering-narwhal"}

This plan identifies **remaining** opportunities to reduce DB write pressure through transactions and batching.\n\nAfter reviewing all write paths in the codebase, most periodic tasks are already well-optimized:\n- `UpdateDuration` — single bulk UPDATE, efficient\n- `StopJobsExceedingWalltimeBy` — single bulk UPDATE, efficient\n- `DeleteJobsBefore` — single bulk DELETE, efficient\n- Footprint worker — already uses `TransactionInit/TransactionAdd/TransactionEnd` per cluster\n- Archiver — chains UpdateFootprint + UpdateEnergy + MarkArchived into single `sq.Update` statement, efficient\n\nThe remaining opportunities are in **tag operations**, **TransferCachedJobToMain**, and **job imports**.\n\n---\n\n## Fix 6: Wrap TransferCachedJobToMain in a Transaction\n\n**File:** `internal/repository/jobCreate.go:130-149`\n\nCurrently does INSERT + DELETE as two separate `r.DB.Exec()` calls. If the process crashes between them, the job_cache row is orphaned (duplicate on next SyncJobs).\n\n**Change:** Wrap both operations in a transaction:\n```go\nfunc (r *JobRepository) TransferCachedJobToMain(cacheID int64) (int64, error) {\n tx, err := r.DB.Beginx()\n // INSERT INTO job ... SELECT ... FROM job_cache WHERE id = ?\n // newID from LastInsertId\n // DELETE FROM job_cache WHERE id = ?\n // tx.Commit()\n}\n```\n\n**Impact:** Atomicity + 1 lock acquisition instead of 2. Called per job stop from cache path.\n\n---\n\n## Fix 7: Batch Tag Operations on Job Start (NATS + REST)\n\n**File:** `internal/api/nats.go:228-233` — loops `AddTagOrCreate` per tag\n**File:** `internal/api/job.go` — same pattern in `startJob` REST handler\n\nCurrently each tag does: SELECT tag → INSERT tag (if new) → SELECT job → INSERT jobtag → SELECT tags → archive.UpdateTags. For a job with 5 tags = 30 individual DB operations.\n\n**Change:** Add `BatchAddTagsDirect` to `internal/repository/tags.go`:\n- Accept jobID + slice of tags\n- Begin transaction\n- For each tag: resolve/create tag ID, INSERT jobtag — all within same transaction\n- Commit\n- Single archive.UpdateTags call at the end (outside transaction)\n\nThen update callers:\n- `internal/api/nats.go:228-233` — replace loop with `BatchAddTagsDirect`\n- `internal/api/job.go` (startJob REST handler) — same change\n\n**Keep** existing `AddTagOrCreate` for single-tag use cases (GraphQL, REST tag endpoint).\n\n**Impact:** N tags = 1 transaction + 1 archive update instead of N * 5 separate operations. Most impactful when scheduler sends jobs with multiple tags.\n\n---\n\n## Fix 8: Batch Tag Imports\n\n**File:** `internal/importer/handleImport.go:111-116` — loops `ImportTag` per tag per job\n\nCurrently each tag does: SELECT tag → INSERT tag (if new) → INSERT jobtag. For 100 jobs with 3 tags each = 600+ individual operations.\n\n**Change:** Add `BatchImportTags` to `internal/repository/tags.go`:\n- Accept jobID + slice of (type, name, scope)\n- Begin transaction\n- For each tag: resolve/create tag ID + INSERT jobtag\n- Commit\n\nUpdate `handleImport.go` to call `BatchImportTags` instead of the loop.\n\n**Impact:** Reduces lock acquisitions from 2*N to 1 per job's tags during import. Import is a startup-only operation but can be long-running for large archives.\n\n---\n\n## Fix 9: Wrap RemoveTagByID in a Transaction\n\n**File:** `internal/repository/tags.go:216-244`\n\nCurrently does DELETE FROM jobtag + DELETE FROM tag as two separate operations.

If the process crashes between them, the job_cache row is orphaned (duplicate on next SyncJobs).\n\n**Change:** Wrap both operations in a transaction:\n```go\nfunc (r *JobRepository) TransferCachedJobToMain(cacheID int64) (int64, error) {\n tx, err := r.DB.Beginx()\n // INSERT INTO job ... SELECT ... FROM job_cache WHERE id = ?\n // newID from LastInsertId\n // DELETE FROM job_cache WHERE id = ?\n // tx.Commit()\n}\n```\n\n**Impact:** Atomicity + 1 lock acquisition instead of 2.

After Fix 3: check logs for \"UNIQUE constraint failed\" — should be gone.\n4. Run `go test ./internal/repository/... ./internal/api/... ./internal/auth/...` after all changes.\n5. Load test: simulate burst of 100+ concurrent job start/stop events + node state update with 500 nodes + LDAP sync running simultaneously. Monitor goroutine count and memory.\n"},"sourceToolAssistantUUID":"b4439843-d8a6-40b1-9d71-93da5b44f966","userType":"external","cwd":"/Users/jan/prg/ClusterCockpit/cc-backend","sessionId":"3a41c7a4-abf8-484b-96ae-ee5618eea5ba","version":"2.1.76","gitBranch":"hotfix","slug":"woolly-wandering-narwhal"}

This plan identifies **remaining** opportunities to reduce DB write pressure through transactions and batching.\n\nAfter reviewing all write paths in the codebase, most periodic tasks are already well-optimized:\n- `UpdateDuration` — single bulk UPDATE, efficient\n- `StopJobsExceedingWalltimeBy` — single bulk UPDATE, efficient\n- `DeleteJobsBefore` — single bulk DELETE, efficient\n- Footprint worker — already uses `TransactionInit/TransactionAdd/TransactionEnd` per cluster\n- Archiver — chains UpdateFootprint + UpdateEnergy + MarkArchived into single `sq.Update` statement, efficient\n\nThe remaining opportunities are in **tag operations**, **TransferCachedJobToMain**, and **job imports**.\n\n---\n\n## Fix 6: Wrap TransferCachedJobToMain in a Transaction\n\n**File:** `internal/repository/jobCreate.go:130-149`\n\nCurrently does INSERT + DELETE as two separate `r.DB.Exec()` calls. If the process crashes between them, the job_cache row is orphaned (duplicate on next SyncJobs).\n\n**Change:** Wrap both operations in a transaction:\n```go\nfunc (r *JobRepository) TransferCachedJobToMain(cacheID int64) (int64, error) {\n tx, err := r.DB.Beginx()\n // INSERT INTO job ... SELECT ... FROM job_cache WHERE id = ?\n // newID from LastInsertId\n // DELETE FROM job_cache WHERE id = ?\n // tx.Commit()\n}\n```\n\n**Impact:** Atomicity + 1 lock acquisition instead of 2. Called per job stop from cache path.\n\n---\n\n## Fix 7: Batch Tag Operations on Job Start (NATS + REST)\n\n**File:** `internal/api/nats.go:228-233` — loops `AddTagOrCreate` per tag\n**File:** `internal/api/job.go` — same pattern in `startJob` REST handler\n\nCurrently each tag does: SELECT tag → INSERT tag (if new) → SELECT job → INSERT jobtag → SELECT tags → archive.UpdateTags. For a job with 5 tags = 30 individual DB operations.\n\n**Change:** Add `BatchAddTagsDirect` to `internal/repository/tags.go`:\n- Accept jobID + slice of tags\n- Begin transaction\n- For each tag: resolve/create tag ID, INSERT jobtag — all within same transaction\n- Commit\n- Single archive.UpdateTags call at the end (outside transaction)\n\nThen update callers:\n- `internal/api/nats.go:228-233` — replace loop with `BatchAddTagsDirect`\n- `internal/api/job.go` (startJob REST handler) — same change\n\n**Keep** existing `AddTagOrCreate` for single-tag use cases (GraphQL, REST tag endpoint).\n\n**Impact:** N tags = 1 transaction + 1 archive update instead of N * 5 separate operations. Most impactful when scheduler sends jobs with multiple tags.\n\n---\n\n## Fix 8: Batch Tag Imports\n\n**File:** `internal/importer/handleImport.go:111-116` — loops `ImportTag` per tag per job\n\nCurrently each tag does: SELECT tag → INSERT tag (if new) → INSERT jobtag. For 100 jobs with 3 tags each = 600+ individual operations.\n\n**Change:** Add `BatchImportTags` to `internal/repository/tags.go`:\n- Accept jobID + slice of (type, name, scope)\n- Begin transaction\n- For each tag: resolve/create tag ID + INSERT jobtag\n- Commit\n\nUpdate `handleImport.go` to call `BatchImportTags` instead of the loop.\n\n**Impact:** Reduces lock acquisitions from 2*N to 1 per job's tags during import. Import is a startup-only operation but can be long-running for large archives.\n\n---\n\n## Fix 9: Wrap RemoveTagByID in a Transaction\n\n**File:** `internal/repository/tags.go:216-244`\n\nCurrently does DELETE FROM jobtag + DELETE FROM tag as two separate operations. If the second fails, jobtag rows are gone but the orphaned tag row remains.\n\n**Change:**\n```go\nfunc (r *JobRepository) RemoveTagByID(tagID int64) error {\n jobIds, err := r.FindJobIdsByTag(tagID)\n // ...\n tx, err := r.DB.Beginx()\n defer tx.Rollback()\n // DELETE FROM jobtag WHERE tag_id = ? (on tx)\n // DELETE FROM tag WHERE id = ? (on tx)\n tx.Commit()\n go r.removeTagFromArchiveJobs(jobIds)\n}\n```\n\n**Impact:** Atomicity for tag deletion. Low frequency (admin operation) but prevents orphaned data.\n\n---\n\n## Implementation Order\n\n1. **Fix 6** (TransferCachedJobToMain) — trivial, fixes a real atomicity bug\n2. **Fix 7** (batch tags on job start) — biggest remaining contention reduction for NATS path\n3. **Fix 8** (batch tag imports) — only affects import, but easy once Fix 7 pattern exists\n4. **Fix 9** (RemoveTagByID transaction) — minor, correctness improvement\n\n---\n\n## Files to Modify\n\n| File | Changes |\n|------|---------|\n| `internal/repository/jobCreate.go` | Fix 6: wrap TransferCachedJobToMain in transaction |\n| `internal/repository/tags.go` | Fix 7: add `BatchAddTagsDirect`; Fix 8: add `BatchImportTags`; Fix 9: transaction in RemoveTagByID |\n| `internal/api/nats.go` | Fix 7: use BatchAddTagsDirect in handleStartJob |\n| `internal/api/job.go` | Fix 7: use BatchAddTagsDirect in startJob REST handler |\n| `internal/importer/handleImport.go` | Fix 8: use BatchImportTags |\n\n---\n\n## What NOT to Change\n\nThese are already efficient and don't need modification:\n- `UpdateDuration` — single bulk UPDATE\n- `StopJobsExceedingWalltimeBy` — single bulk UPDATE\n- `DeleteJobsBefore` — single bulk DELETE\n- Footprint worker — already transactional per cluster\n- Archiver — already chains SETs into single UPDATE via Squirrel builder\n- `UpdateUser` — admin-only, very low frequency, not worth the complexity\n- `AddUser` deprecated metrics loop — marked DEPRECATED, will be removed; not worth optimizing\n\n---\n\n## Verification\n\n1. `go test ./internal/repository/... ./internal/api/... ./internal/importer/...`\n2. After Fix 6: verify `TransferCachedJobToMain` atomicity — stop a job that's in cache, check job table has correct ID and cache is empty\n3. After Fix 7: start a job with multiple tags via NATS — verify all tags appear, check that only 1 transaction was used (enable debug logging)\n4. After Fix 9: delete a tag via GraphQL — verify both tag and jobtag rows removed atomically\n","planFilePath":"/Users/jan/.claude/plans/woolly-wandering-narwhal.md"},"caller":{"type":"direct"}}],"stop_reason":"tool_use","stop_sequence":null,"usage":{"input_tokens":3,"cache_creation_input_tokens":738,"cache_read_input_tokens":118843,"output_tokens":300,"server_tool_use":{"web_search_requests":0,"web_fetch_requests":0},"service_tier":"standard","cache_creation":{"ephemeral_1h_input_tokens":738,"ephemeral_5m_input_tokens":0},"inference_geo":"","iterations":[],"speed":"standard"}},"requestId":"req_011CZ6bHiNNrnrkcJwPQJx9K","type":"assistant","uuid":"848e3ef2-64b6-4bdd-896f-916bbfdcc791","timestamp":"2026-03-16T10:21:23.986Z","userType":"external","cwd":"/Users/jan/prg/ClusterCockpit/cc-backend","sessionId":"3a41c7a4-abf8-484b-96ae-ee5618eea5ba","version":"2.1.76","gitBranch":"hotfix","slug":"woolly-wandering-narwhal"}
