(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` -

Further Refinements:**\nCreated additional indexes including time-based sorting combinations:\n- `jobs_cluster_duration_starttime` - (cluster, duration, start_time)\n- `jobs_cluster_starttime_duration` - (cluster, start_time, duration)\n- `jobs_user_starttime_duration` - (hpc_user, start_time, duration)\n- `jobs_user_duration_starttime` - (hpc_user, duration, start_time)\n- `jobs_cluster_jobstate_starttime_duration` - (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` - (job_state) - single column\n - `jobs_cluster_jobstate` - (cluster, job_state)\n - And many composite indexes with job_state as leading or subsequent columns\n\n2. **Is there an index on `start_time`?**\n - **YES** - Multiple indexes include `start_time`:\n - `jobs_starttime` - (start_time) - single column\n - `job_by_starttime` - (start_time) - from initial migration\n - And many composite indexes with start_time\n\n3. **Is there a composite index on `(job_state, start_time)`?**\n - **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` - (cluster, subcluster)\n- `nodestates_timestamp` - (time_stamp)\n- `nodestates_state_timestamp` - (node_state, time_stamp)\n- `nodestates_health_timestamp` - (health_state, time_stamp)\n- `nodestates_nodeid_state` - (node_id, node_state)\n- `nodestates_nodeid_health` - (node_id, health_state)\n- `nodestates_nodeid_timestamp` - (node_id, time_stamp DESC)\n\n### **Tag Indexes (Migration 10):**\n- `tags_jobid` - (job_id) on jobtag table\n- `tags_tagid` - (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)\n<usage>total_tokens: 60120\ntool_uses: 26\nduration_ms: 112747</usage>"}]}]},"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.

(start_time)\n- `jobs_duration` - (duration)\n- `jobs_numnodes` - (num_nodes)\n- `jobs_numhwthreads` - (num_hwthreads)\n- `jobs_numacc` - (num_acc)\n- `jobs_energy` - (energy)\n\nAnd many more cluster+partition combinations...\n\n#### **Migration 09 (09_add-job-cache.up.sql) - Further Refinements:**\nCreated additional indexes including time-based sorting combinations:\n- `jobs_cluster_duration_starttime` - (cluster, duration, start_time)\n- `jobs_cluster_starttime_duration` - (cluster, start_time, duration)\n- `jobs_user_starttime_duration` - (hpc_user, start_time, duration)\n- `jobs_user_duration_starttime` - (hpc_user, duration, start_time)\n- `jobs_cluster_jobstate_starttime_duration` - (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` - (job_state) - single column\n - `jobs_cluster_jobstate` - (cluster, job_state)\n - And many composite indexes with job_state as leading or subsequent columns\n\n2. **Is there an index on `start_time`?**\n - **YES** - Multiple indexes include `start_time`:\n - `jobs_starttime` - (start_time) - single column\n - `job_by_starttime` - (start_time) - from initial migration\n - And many composite indexes with start_time\n\n3. **Is there a composite index on `(job_state, start_time)`?**\n - **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` - (cluster, subcluster)\n- `nodestates_timestamp` - (time_stamp)\n- `nodestates_state_timestamp` - (node_state, time_stamp)\n- `nodestates_health_timestamp` - (health_state, time_stamp)\n- `nodestates_nodeid_state` - (node_id, node_state)\n- `nodestates_nodeid_health` - (node_id, health_state)\n- `nodestates_nodeid_timestamp` - (node_id, time_stamp DESC)\n\n### **Tag Indexes (Migration 10):**\n- `tags_jobid` - (job_id) on jobtag table\n- `tags_tagid` - (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.

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). This is worth investigating separately but is a schema/migration concern, not a code bug."}],"stop_reason":"end_turn","stop_sequence":null,"usage":{"input_tokens":1,"cache_creation_input_tokens":153,"cache_read_input_tokens":120540,"output_tokens":500,"server_tool_use":{"web_search_requests":0,"web_fetch_requests":0},"service_tier":"standard","cache_creation":{"ephemeral_1h_input_tokens":153,"ephemeral_5m_input_tokens":0},"inference_geo":"","iterations":[],"speed":"standard"}},"requestId":"req_011CYveq9QSvRtPQukPDHvUy","type":"assistant","uuid":"09019982-a241-40fa-b6cb-6b8920303b5c","timestamp":"2026-03-11T04:22:02.158Z"}
