tensorchord/VectorChord
Scalable, fast, and disk-friendly vector search in Postgres, the successor of pgvecto.rs.
Implements RaBitQ quantization with autonomous reranking to achieve 4-26x better storage efficiency than alternatives, indexing 100M vectors in 20 minutes through hierarchical K-means and optimized disk I/O. Scales to 1B+ vectors via dimensionality reduction and sampling while maintaining memory bounds. Maintains full pgvector API compatibility, allowing drop-in replacement without application changes.
