I guess core data is pretty much an EAV Db on top of SQLite

It's got some kind of orm thing though

Could you run Datascript via JavaScript Core? :thinking_face:

Someone suggested something like that. Perhaps.

It’s a lot of overhead just to use an in memory db. Feels bad to run a whole js vm too lol

It's probably not the answer you're looking for, but you can monkey-patch DataScript to use any kind of storage backend that can model a sorted map, e.g. https://github.com/hraberg/datascript-mapdb/blob/master/src/datascript_mapdb/core.clj
