Qdrant is an open-source vector database written in Rust. In the September 2023 edition of the Radar, we talked about pgvector, a PostgreSQL extension for vector search. However, if you have to scale the vector database horizontally across nodes, we encourage you to assess Qdrant. It has built-in single instruction, multiple data (SIMD) acceleration support for improved search performance, and it helps you associate JSON payloads with vectors.
