[2026-05-14T18:09:44.639Z] RESULT ============================================================ { "success": true, "output": "Now I have a complete picture. Let me provide an honest, targeted analysis.\n\n---\n\n## Performance Analysis: `/home/code/infinite`\n\n**Important context first:** This codebase contains **no application source code** — no React components, no backend services, no ORM layer. It is a claude-flow orchestration configuration project. Most of the requested analysis categories (React re-renders, N+1 in application code, memory leaks) have nothing to analyze. What follows covers the two analyzable artifacts: `data/memory/schema.sql` and `claude-flow.config.json`.\n\n---\n\n### 1. N+1 Query Patterns — SQL Schema\n\nThe schema has no application query layer, but the table design has several structural patterns that will produce N+1 behavior at the call site:\n\n**Self-referential `parent_id` in `patterns` — recursive N+1**\n```sql\n-- Current: traversing pattern lineage requires N queries\nparent_id TEXT REFERENCES patterns(id)\n```\nAny code that walks pattern version chains will issue one query per ancestor. Fix with a recursive CTE:\n```sql\n-- Add a closure table or use a WITH RECURSIVE query at the call site:\nWITH RECURSIVE lineage AS (\n SELECT * FROM patterns WHERE id = ?\n UNION ALL\n SELECT p.* FROM patterns p\n JOIN lineage l ON p.id = l.parent_id\n)\nSELECT * FROM lineage;\n```\n\n**`trajectory_steps` fetched per trajectory — classic N+1**\n```sql\n-- Fetching all steps for a list of trajectories triggers N queries\ntrajectory_id TEXT NOT NULL REFERENCES trajectories(id)\n```\nThe `idx_steps_trajectory` index is there, but without a batched query, each trajectory fetch triggers a separate steps lookup. The call site should use:\n```sql\nSELECT ts.* FROM trajectory_steps ts\nWHERE ts.trajectory_id IN (SELECT id FROM trajectories WHERE session_id = ?);\n```\n\n---\n\n### 2. Missing Indexes — High Impact\n\nThese columns are unindexed but almost certainly appear in WHERE clauses:\n\n| Table | Missing Index | Impact |\n|-------|--------------|--------|\n| `memory_entries` | `expires_at` | Expiry cleanup scans the entire table |\n| `sessions` | `expires_at`, `status`, `project_path` | Session lookups do full scans |\n| `trajectories` | `session_id`, `status` | Every session→trajectory join is unindexed |\n| `patterns` | `parent_id` | Version lineage traversal is unindexed |\n\n```sql\n-- Add these:\nCREATE INDEX IF NOT EXISTS idx_memory_expires ON memory_entries(expires_at)\n WHERE expires_at IS NOT NULL;\n\nCREATE INDEX IF NOT EXISTS idx_sessions_status ON sessions(status);\nCREATE INDEX IF NOT EXISTS idx_sessions_project ON sessions(project_path);\nCREATE INDEX IF NOT EXISTS idx_sessions_expires ON sessions(expires_at)\n WHERE expires_at IS NOT NULL;\n\nCREATE INDEX IF NOT EXISTS idx_trajectories_session ON trajectories(session_id);\nCREATE INDEX IF NOT EXISTS idx_trajectories_status ON trajectories(status);\n\nCREATE INDEX IF NOT EXISTS idx_patterns_parent ON patterns(parent_id)\n WHERE parent_id IS NOT NULL;\n```\n\nThe partial index form (`WHERE ... IS NOT NULL`) skips NULL rows, keeping the index small and fast for nullable columns.\n\n---\n\n### 3. Missing Composite Indexes — Common Filter Combinations\n\nThe existing single-column indexes on `memory_entries` won't satisfy multi-column filters efficiently:\n\n```sql\n-- Likely hot query: active entries in a namespace by type\n-- Current plan: intersect 3 separate indexes (slow for large tables)\nSELECT * FROM memory_entries\nWHERE namespace = ? AND status = 'active' AND type = ?;\n\n-- Fix: one composite index covers this exactly\nCREATE INDEX IF NOT EXISTS idx_memory_ns_status_type\n ON memory_entries(namespace, status, type);\n\n-- Likely hot query: find stale/cold entries for eviction\n-- Current: two separate index scans merged\nSELECT * FROM memory_entries\nWHERE status = 'active' ORDER BY last_accessed_at ASC LIMIT 100;\n\n-- Fix: composite covering index\nCREATE INDEX IF NOT EXISTS idx_memory_status_accessed\n ON memory_entries(status, last_accessed_at);\n\n-- Patterns: active patterns by type, ranked by confidence\nCREATE INDEX IF NOT EXISTS idx_patterns_type_status_conf\n ON patterns(pattern_type, status, confidence DESC);\n```\n\n---\n\n### 4. Caching Opportunities — Configuration\n\nIn `claude-flow.config.json`:\n\n```json\n\"memory\": {\n \"cacheSize\": 1000\n}\n```\n\n**Issue:** `cacheSize: 1000` is a flat item count. Without a TTL on the in-memory cache, hot patterns/memories never evict — cold entries accumulate until the cache exceeds working set size and thrashes. The schema has `last_accessed_at` and `access_count` fields designed for LRU/LFU eviction — ensure the cache implementation actually uses them.\n\n**healthCheckInterval** is 30s:\n```json\n\"swarm\": {\n \"healthCheckInterval\": 30000\n}\n```\nAt 8 agents each probing every 30s, this is 8 SQLite writes/reads per 30s for health state — benign at this scale but worth batching into a single `UPDATE ... WHERE id IN (...)` if the agent count grows.\n\n---\n\n### 5. React Re-renders, Memory Leaks, Redundant Computations\n\n**Not applicable.** There are zero React components, no frontend code, and no server-side computation code in this repository. These analysis categories require source files that don't exist here.\n\n---\n\n### Summary — Actionable Priority\n\n| Priority | Fix | Effort |\n|----------|-----|--------|\n| High | Add `idx_trajectories_session`, `idx_sessions_status/project` | One migration |\n| High | Add partial indexes on `expires_at` columns | One migration |\n| Medium | Add composite `idx_memory_ns_status_type` | One migration |\n| Medium | Replace N+1 trajectory step fetches with IN-clause batches | Call-site change |\n| Low | Add WITH RECURSIVE for pattern lineage | Call-site change |\n| Low | Verify cache eviction uses `last_accessed_at` LRU | Implementation audit |\n\nThe index additions can all go into a single `schema_v3.1.sql` migration file.
