Vector databases are used to store embeddings.

  But why is that? I’m sure it’s the ‘best’ way to do things, but it also means more infrastructure which for simple apps isn’t worth the hassle. I should use redis for queues but often I’ll just use a table in a SQLite database. For small scale projects I find it works fine, I’m wondering what an equivalent simple option for embeddings would be.

    Perhaps sqlite-vss? It adds vector searches to sqlite. https://github.com/asg017/sqlite-vss https://github.com/asg017/sqlite-vss

  check out https://github.com/tembo-io/pg_vectorize https://github.com/tembo-io/pg_vectorize - we're taking it a little bit beyond just the storage and index. The project uses pgvector for the indices and distance operators, but also adds a simpler API, hooks into pre-trained embedding models, and helps you keep embeddings updated as data changes/grows
