My 2022 wish list is a Postgres plugin that adds vector + AKNN support that plays well with relational queries. There are so many use cases of that.
I believe Ant Financial has published an open source one but iirc the English language documentation is sparse.
- ccleve 5y agoDo you have a link? I'd like to see it. I googled and did not find much pertaining to "ant financial" and "postgres". Perhaps your google-fu is better than mine...
- etiennedi 5y agoCheckout the open source vector search engine Weaviate: https://github.com/semi-technologies/weaviate https://github.com/semi-technologies/weaviate It’s not a relational db, but it supports Graph-like connections between objects, which makes it really easy to model your relations.

- akane 5y agoCheck out pgvector: https://github.com/ankane/pgvector https://github.com/ankane/pgvector (disclosure: am author) It uses IVFFlat indexing, but could be extended to support product quantization / ScaNN.
