NOT ON THE CURRENT EDITION
This blip is not on the current edition of the Radar. If it was on one of the last few editions, it is likely that it is still relevant. If the blip is older, it might no longer be relevant and our assessment might be different today. Unfortunately, we simply don't have the bandwidth to continuously review blips from previous editions of the Radar.

VectorChord is a PostgreSQL extension for vector similarity search, developed by the creators of pgvecto.rs as its successor. It’s open source, compatible with pgvector data types and designed for disk-efficient, high-performance vector search. It employs inverted file indexing (IVF) along with RaBitQ quantization to enable fast, scalable and accurate vector search while significantly reducing computation demands. Like other PostgresSQL extensions in this space, it leverages the PostgreSQL ecosystem, allowing vector search alongside standard transactional operations. Though still in its early stages, VectorChord is worth assessing for vector search workloads.
