Supercharge pgvector: 4x Faster HNSW with AlloyDB
AlloyDB is a fully managed, PostgreSQL-compatible database service built for your most demanding enterprise workloads. It combines the best of open source PostgreSQL with Google’s advanced technology, offering massive scalability, high availability, and native AI capabilities. It serves as a performant relational store, a unified backend for vector and full text search, and an analytics engine that is up to 100x faster than standard PostgreSQL.
Vector search is the foundation of modern AI and Retrieval Augmented Generation (RAG) applications. For developers using AlloyDB and other PostgreSQL databases, pgvector is a widely adopted extension for storing, indexing, and querying vector embeddings, and HNSW (Hierarchical Navigable Small World) is a highly efficient graph-based algorithm designed for approximate nearest neighbor search across multi-layered structures. With columnar engine accelerated HNSW in AlloyDB (now in preview), you can achieve up to 4x higher queries per second (QPS) for vector search compared to standard PostgreSQL HNSW.
