We're thrilled to announce the general availability of DiskANN—one of the fastest vector indexing algorithms on the market—on Azure Database for PostgreSQL. Developed at Microsoft Research and used extensively at Microsoft in global services such as Bing and Microsoft 365, DiskANN enables you to build high-performance and scalable generative AI (GenAI) applications that surpass pgvector index types—hierarchical navigable small world (HNSW) and inverted file with flat compression (IVFFlat)—in both speed and accuracy. Using DiskANN in PostgreSQL dramatically improves query performance and reduces latency as you scale your GenAI applications.
