Do we really need a specialized vector database?

• pgvector

  78 9,349 9.9 C

  Open-source vector similarity search for Postgres

  

Since we see vectors as a new data type in traditional databases, let's take a look at how to support vector data types in traditional databases, using PostgreSQL as an example. pgvector is an open-source PostgreSQL plugin that supports vector data types. pgvector uses exact calculation by default, but it also supports building an IVFFlat index and precomputing ANN results using the IVFFlat algorithm, sacrificing calculation accuracy for performance.

• faiss-rs

  2 185 6.3 Rust

  Rust language bindings for Faiss

Rewriting pgvector in Rust can enable the code to be organized in a more modern and extensible way. Rust's ecosystem is also very rich, with existing Rust bindings such as faiss-rs.

• InfluxDB

  www.influxdata.com featured

  Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.

  

• pgvecto.rs

  17 1,390 9.3 Rust

  Scalable, Low-latency and Hybrid-enabled Vector Search in Postgres. Revolutionize Vector Search, not Database.

  

As a result, pgvecto.rs was created. pgvecto.rs currently supports exact vector query operations and three distance calculation operators. Work is underway to design and implement index support. In addition to IVFFlat, we also hope to support more indexing algorithms such as DiskANN, SPTAG, and ScaNN. We welcome contributions and feedback from the community!
