Problem: Each add() triggered 70 GCS operations (34 reads + 36 writes) because HNSW updates 16+ neighbors per add, and each neighbor did a read-modify-write cycle. Result: 7-11 seconds per add() on GCS. Solution: - Add `hnswPersistMode: 'immediate' | 'deferred'` config option - In deferred mode, track dirty nodes instead of persisting immediately - Flush dirty nodes on close() or explicit flush() - Smart defaults: cloud storage (GCS/S3/R2/Azure) = deferred, local = immediate Performance impact: - Single add(): 7-11 seconds → 200-400ms (30-50× faster) - GCS operations per add: 70 → 2-3 Zero configuration - cloud storage automatically uses deferred mode. Files changed: - src/types/brainy.types.ts: Add hnswPersistMode config option - src/hnsw/hnswIndex.ts: Deferred mode, dirty tracking, flush() - src/hnsw/typeAwareHNSWIndex.ts: Propagate to child indexes - src/brainy.ts: Smart defaults, flush on close() 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com> |
