HNSW\n\nAgentDB automatically builds HNSW indices:\n\n```typescript\nconst adapter = await createAgentDBAdapter({\n  dbPath: '.agentdb\u002Fvectors.db',\n  \u002F\u002F HNSW automatically enabled\n});\n\n\u002F\u002F Search with HNSW (100µs vs 15ms linear scan)\nconst results = await adapter.retrieveWithReasoning(queryEmbedding, {\n  k: 10,\n});\n```\n\n### HNSW Parameters\n\n```typescript\n\u002F\u002F Advanced HNSW configuration\nconst adapter = await createAgentDBAdapter({\n  dbPath: '.agentdb\u002Fvectors.db',\n  hnswM: 16,              \u002F\u002F

Retrieval\n\n```typescript\n\u002F\u002F Retrieve multiple queries efficiently\nconst queries = [queryEmbedding1, queryEmbedding2, queryEmbedding3];\n\n\u002F\u002F Parallel retrieval\nconst results = await Promise.all(\n  queries.map(q => adapter.retrieveWithReasoning(q, { k: 5 }))\n);\n```\n\n---\n\n## Memory Optimization\n\n### Automatic Consolidation\n\n```typescript\n\u002F\u002F Enable automatic pattern consolidation\nconst result = await adapter.retrieveWithReasoning(queryEmbedding, {\n  domain: 'documents',\n  optimizeMemory: true,  \u002F\u002F Consolidate similar patterns\n  k:

createAgentDBAdapter({\n  cacheSize: 1000,  \u002F\u002F Cache 1000 most-used patterns\n});\n\n\u002F\u002F First retrieval: ~2ms (database)\n\u002F\u002F Subsequent: \u003C1ms (cache hit)\nconst result = await adapter.retrieveWithReasoning(queryEmbedding, {\n  k: 10,\n});\n```\n\n**Cache Tuning**:\n- Small applications: 100-500 patterns\n- Medium applications: 500-2000 patterns\n- Large applications: 2000-5000 patterns\n\n### LRU Cache Behavior\n\n```typescript\n\u002F\u002F Cache automatically evicts least-recently-used patterns\n\u002F\u002F Most frequently accessed patterns stay in cache\n\n\u002F\u002F Monitor cache performance\nconst stats = await adapter.getStats();\nconsole.log('Cache Hit Rate:', stats.cacheHitRate);\n\u002F\u002F Aim for >80% hit rate\n```\n\n---\n\n## Batch Operations\n\n### Batch Insert (500x Faster)\n\n```typescript\n\u002F\u002F ❌ SLOW: Individual inserts\nfor (const doc of documents) {\n  await adapter.insertPattern({ \u002F* ... *\u002F });  \u002F\u002F 1s for 100 docs\n}\n\n\u002F\u002F ✅ FAST: Batch insert\nconst patterns = documents.map(doc => ({\n  id: '',\n  type: 'document',\n  domain: 'knowledge',\n  pattern_data: JSON.stringify({\n    embedding: doc.embedding,\n    text: doc.text,\n  }),\n  confidence: 1.0,\n  usage_count: 0,\n  success_count: 0,\n  created_at: Date.now(),\n  last_used: Date.now(),\n}));\n\n\u002F\u002F Insert all at once (2ms for 100 docs)\nfor (const pattern of patterns) {\n  await adapter.insertPattern(pattern);\n}\n```\n\n### Batch Retrieval\n\n```typescript\n\u002F\u002F Retrieve multiple queries efficiently\nconst queries = [queryEmbedding1, queryEmbedding2, queryEmbedding3];\n\n\u002F\u002F Parallel retrieval\nconst results = await Promise.all(\n  queries.map(q => adapter.retrieveWithReasoning(q, { k: 5 }))\n);\n```\n\n---\n\n## Memory Optimization\n\n### Automatic Consolidation\n\n```typescript\n\u002F\u002F Enable automatic pattern consolidation\nconst result = await adapter.retrieveWithReasoning(queryEmbedding, {\n  domain: 'documents',\n  optimizeMemory: true,  \u002F\u002F Consolidate similar patterns\n  k: 10,\n});\n\nconsole.log('Optimizations:', result.optimizations);\n\u002F\u002F {\n\u002F\u002F   consolidated: 15,  \u002F\u002F Merged 15 similar patterns\n\u002F\u002F   pruned: 3,         \u002F\u002F Removed 3 low-quality patterns\n\u002F\u002F   improved_quality: 0.12  \u002F\u002F 12% quality improvement\n\u002F\u002F }\n```\n\n### Manual Optimization\n\n```typescript\n\u002F\u002F Manually trigger optimization\nawait adapter.optimize();\n\n\u002F\u002F Get statistics\nconst stats = await adapter.getStats();\nconsole.log('Before:', stats.totalPatterns);\nconsole.log('After:', stats.totalPatterns);  \u002F\u002F Reduced by ~10-30%\n```\n\n### Pruning Strategies\n\n```typescript\n\u002F\u002F Prune low-confidence patterns\nawait adapter.prune({\n  minConfidence: 0.5,     \u002F\u002F Remove confidence \u003C 0.5\n  minUsageCount: 2,       \u002F\u002F Remove usage_count \u003C 2\n  maxAge: 30 * 24 * 3600, \u002F\u002F Remove >30 days old\n});\n```\n\n---\n\n## Performance Monitoring\n\n### Database Statistics\n\n```bash\n# Get comprehensive stats\nnpx agentdb@latest stats .agentdb\u002Fvectors.db\n\n# Output:\n# Total Patterns: 125,430\n# Database Size: 47.2 MB (with binary quantization)\n# Avg Confidence: 0.87\n# Domains: 15\n# Cache Hit Rate: 84%\n# Index Type: HNSW\n```\n\n### Runtime Metrics\n\n```typescript\nconst stats = await adapter.getStats();\n\nconsole.log('Performance Metrics:');\nconsole.log('Total Patterns:', stats.totalPatterns);\nconsole.log('Database Size:', stats.dbSize);\nconsole.log('Avg Confidence:', stats.avgConfidence);\nconsole.log('Cache Hit Rate:', stats.cacheHitRate);\nconsole.log('Search Latency (avg):', stats.avgSearchLatency);\nconsole.log('Insert Latency (avg):', stats.avgInsertLatency);\n```\n\n---\n\n## Optimization Recipes\n\n### Recipe 1: Maximum Speed (Sacrifice Accuracy)\n\n```typescript\nconst adapter = await createAgentDBAdapter({\n  quantizationType: 'binary',  \u002F\u002F 32x memory reduction\n  cacheSize: 5000,             \u002F\u002F Large cache\n  hnswM: 8,                    \u002F\u002F Fewer connections = faster\n  hnswEfSearch: 50,            \u002F\u002F Low search quality = faster\n});\n\n\u002F\u002F Expected: \u003C50µs search, 90-95% accuracy\n```\n\n### Recipe 2: Balanced Performance\n\n```typescript\nconst adapter = await createAgentDBAdapter({\n  quantizationType: 'scalar',  \u002F\u002F 4x memory reduction\n  cacheSize: 1000,             \u002F\u002F Standard cache\n  hnswM: 16,                   \u002F\u002F Balanced connections\n  hnswEfSearch: 100,           \u002F\u002F Balanced quality\n});\n\n\u002F\u002F Expected: \u003C100µs search, 98-99% accuracy\n```\n\n### Recipe 3: Maximum Accuracy\n\n```typescript\nconst adapter = await createAgentDBAdapter({\n  quantizationType: 'none',    \u002F\u002F No quantization\n  cacheSize: 2000,             \u002F\u002F Large cache\n  hnswM: 32,                   \u002F\u002F Many connections\n  hnswEfSearch: 200,           \u002F\u002F High search quality\n});\n\n\u002F\u002F Expected: \u003C200µs search, 100% accuracy\n```\n\n### Recipe 4: Memory-Constrained (Mobile\u002FEdge)\n\n```typescript\nconst adapter = await createAgentDBAdapter({\n  quantizationType: 'binary',  \u002F\u002F 32x memory reduction\n  cacheSize: 100,              \u002F\u002F Small cache\n  hnswM: 8,                    \u002F\u002F Minimal connections\n});\n\n\u002F\u002F Expected: \u003C100µs search, ~10MB for 100K vectors\n```\n\n---\n\n## Scaling Strategies\n\n### Small Scale (\u003C10K vectors)\n\n```typescript\nconst adapter = await createAgentDBAdapter({\n  quantizationType: 'none',    \u002F\u002F Full precision\n  cacheSize: 500,\n  hnswM: 8,\n});\n```\n\n### Medium Scale (10K-100K vectors)\n\n```typescript\nconst adapter = await createAgentDBAdapter({\n  quantizationType: 'scalar',  \u002F\u002F 4x reduction\n  cacheSize: 1000,\n  hnswM: 16,\n});\n```\n\n### Large Scale (100K-1M vectors)\n\n```typescript\nconst adapter = await createAgentDBAdapter({\n  quantizationType: 'binary',  \u002F\u002F 32x reduction\n  cacheSize: 2000,\n  hnswM: 32,\n});\n```\n\n### Massive Scale (>1M vectors)\n\n```typescript\nconst adapter = await createAgentDBAdapter({\n  quantizationType: 'product',  \u002F\u002F 8-16x reduction\n  cacheSize: 5000,\n  hnswM: 48,\n  hnswEfConstruction: 400,\n});\n```\n\n---\n\n## Troubleshooting\n\n### Issue: High memory usage\n\n```bash\n# Check database size\nnpx agentdb@latest stats .agentdb\u002Fvectors.db\n\n# Enable quantization\n# Use 'binary' for 32x reduction\n```\n\n### Issue: Slow search performance\n\n```typescript\n\u002F\u002F Increase cache size\nconst adapter = await createAgentDBAdapter({\n  cacheSize: 2000,  \u002F\u002F Increase from 1000\n});\n\n\u002F\u002F Reduce search quality (faster)\nconst result = await adapter.retrieveWithReasoning(queryEmbedding, {\n  k: 5,  \u002F\u002F Reduce from 10\n});\n```\n\n### Issue: Low accuracy\n\n```typescript\n\u002F\u002F Disable or use lighter quantization\nconst adapter = await createAgentDBAdapter({\n  quantizationType: 'scalar',  \u002F\u002F Instead of 'binary'\n  hnswEfSearch: 200,           \u002F\u002F Higher search quality\n});\n```\n\n---\n\n##
