If anyone is interested, I am attempting to revive an open source clone of Datomic called EVA.
As is the original codebase works fine, its just unmaintained. My hope is to clean up the code, make an HTTP layer for a remote peer, and make a Rust embedded peer so that this sort of Database can finally escape the JVM.

If you want to use something open source today that has the same query language but a different data model, https://xtdb.com/ is high quality.
Oh really interesting. I didn't know about that. I was actually going threw the old Mendat code base and was considering using that.
I would really like a pure Rust version of Datomic for embed use cases.
There is all also Datahike, that is going in that direction too. It is maintained and actively developed.
