Vector Databases: A Technical Primer [pdf]

• chromem-go

  3 89 9.5 Go

  Embeddable vector database for Go with Chroma-like interface and zero third-party dependencies. In-memory with optional persistence.

For Python I believe Chroma [1] can be used embedded.

For Go I recently started building chromem-go, inspired by the Chroma interface: https://github.com/philippgille/chromem-go

It's neither advanced nor for scale yet, but the RAG demo works.

• pgvector

  Open-source vector similarity search for Postgres

  

You don't need a dedicated vector db, you can use pgvector.

You could maybe use Cube for euclidean space search, but you're better off using optimized algorithms for embedding space search.

There are options such as Google's ScaNN that may let you go farther before needing to consider specialized databases.
