Yeah, thanks for the suggestion @arosen93 . Definitely no objections to implementing a MongitaStore someday. I looked briefly at mongita as a substitute for mongomock to power MemoryStore, but I noted the following limitations:

mongitadoes not support many query operations including$regexor$exists. It also doesn't support bulk_writeorestimated_document_count` although those can be worked around.

Edit: Looks like we are out of luck there for Mongita.

Mongita is an embedded database. It is not process-safe. When you have multiple clients, a traditional server/client database is the correct choice.

Same for MontyDB, as noted here.

There's nothing in maggma specifically to resolve this, right @munrojm?

Worth jotting down FerretDB here, as highlighted by @utf above. This one seems particularly promising!
