Is there any prior open source work pertaining to having datascript data on a database instead of in memory?

There’s a Datascript-on-RethinkDB project, I believe

Nice, got a link?

https://github.com/runexec/possibledb Is this what you had in mind?

This is probably a very stupid question—to understand datascript source and understand its bottlenecks and how to optimize queries, does one need some background in relational database theory?
