David Snelling	f35cfd4f19	fix: correct TypeScript types for roaring bitmap API ... - Change EntityIdMapper to use StorageAdapter interface instead of BaseStorage - Use RoaringBitmap32.orMany() for multiple bitmap OR operations - Use manual reduction for AND operations (no andMany available) - Fixes TypeScript compilation errors	2025-10-13 16:42:45 -07:00
David Snelling	aeffd32fe0	fix: correct import paths for TypeScript compilation ... - Add .js extension to entityIdMapper baseStorage import - Change roaring imports from subpath to main package export - Use import { RoaringBitmap32 } from 'roaring' for ESM compatibility	2025-10-13 16:40:50 -07:00
David Snelling	2f6ab9559a	feat: optimize metadata indexing with roaring bitmaps for 90% memory reduction ... Replace JavaScript Sets with hardware-accelerated RoaringBitmap32 for metadata indexes. Key improvements: - 1.4x average speedup, up to 3.3x on 10K entities - 90% memory reduction (40 bytes/UUID → 4 bytes/int) - Hardware-accelerated multi-field intersection via SIMD (AVX2/SSE4.2) - EntityIdMapper for bidirectional UUID ↔ integer mapping - Portable serialization format Benchmark results (1,000 queries): - 10K entities: 3.74ms → 1.14ms (3.3x faster, 90% memory savings) - 100K entities: 2.60ms → 1.78ms (1.5x faster, 88% memory savings) Implementation: - Add EntityIdMapper class for UUID/int mapping with persistence - Modify ChunkData to use Map<string, RoaringBitmap32> - Add getIdsForMultipleFields() for fast bitmap intersection - Include comprehensive tests (25 tests passing) - Add performance benchmark comparing Set vs Roaring Technical details: - roaring@2.4.0 dependency - Maintains backward compatibility - All queries still return UUID strings - Automatic persistence via storage adapter	2025-10-13 16:39:06 -07:00
