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\t\"golang.org/x/sync/errgroup\"\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.

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.
