How does it compare with the since-discontinued embedded graph database cozodb? https://github.com/cozodb/cozo

It also used datalog, written in rust

Great to see tho, I'm always eagerly hoping for a successful embedded graph database. Most recently my hope was for kuzudb, but they got acquihired; though it's still open-sourcing' as LadybugDB.

Highly recommend taking inspiration from Kuzudb/Ladybugdb and cozodb.

Godspeed!

Maintainer of LadybugDB here. I'm reviewing a PR to transpile GQL to Cypher.

It should be possible to transpile datalog or another query language that is interesting.

Implementing storage and secondary indicies is the hard part.

Won't comment on rewriting the DB in Rust beyond what's in GitHub discussions.

    Hi adsharma! Great to see you here! I've been thinking about a data query IR that databases could expose. There are IRs for algebra like Substrait, so maybe something similar could work here, maybe with binding info. I don't mean a low-level physical/plan IR but more like a "logical IR" that the optimizer can optimize :)
