I’ve been using FDB for toy projects for a while. It’s truly rock solid. In my experience it’s the best open source database I’ve used, including mariadb, Postgres and cockroach. That being said, I wish there were more layers as the functionality out of the box is very very limited.

Ideally someone could implement the firestore or dynamodb api on top.

Is basically distributed SQLite backed by FDB. I’ve been scared to use it since I don’t know rust and can’t attest to if mvcc had been implemented correctly.

In using this I actually realized how coupled the storage engine is to the storage system and how few open source projects make the storage engine easily swap-able.

The record layer https://github.com/FoundationDB/fdb-record-layer which allows to store protobuf, and define the primary keys and index directly on those proto fields is truly amazing:
