About
Vector Indexing & Optimization
Overview
Index types, quantization, and reindexing strategies for LanceDB vector search performance.
Quick Reference
Index Types
| Index | Best For | Quantization | |-------|----------|-------------| | IVFPQ | General purpose | Product Quantization | | IVFHNSWSQ | High recall | Scalar Quantization | | IVFHNSWPQ | Large datasets | Product Quantization | | IVFFLAT | Small datasets, 100% recall | None | | IVF_RQ | Binary vectors | RaBitQ (1 bit/dim) |
Quantization
| Type | Bits/Dim | Compression | Recall Impact | |------|----------|-------------|---------------| | None | 32 | 1x | None | | SQ | 8 | 4x | Minimal | | PQ | 4-8 | 4-8x | Moderate | | RQ (RaBitQ) | 1 | 32x | Low-moderate |
