Check out CozoDB, the embedded datalog-queried hybrid relational+vector+graph database written in Rust: https://www.cozodb.org/

I used it in a toy application and it was awesome.

This appears to be a dream database from the future.

It seems like the project has been abandoned? Last commit a year ago.
