What problem does it solve?

Large-scale vector search demands more RAM than is affordable, making naive HNSW impractical for 100M+ vectors. DiskANN with pgvectorscale enables memory-efficient indexing and query processing on commodity hardware.

Core Features & Use Cases

  • DiskANN-based index for large embeddings with streaming access.
  • SBQ-based vector compression to shrink index memory footprint with minimal recall loss.
  • Suitable for RAG pipelines, knowledge bases, and enterprise document corpora requiring scalable vector search.

Quick Start

Create a StreamingDiskANN index for your embeddings (vector(768)) using SBQ storage and run a sample top-10 nearest-neighbor query.
