The FoundationDB Document Layer is compatibile with MongoDb 3.x API. https://github.com/FoundationDB/fdb-document-layer .and you get the transaction Al integrity.

I stopped using MongoDB and switched to this.

The document layer seems to be unmaintained since the end of 2019 and has quite a few bugs. The 1.8.x releases fixed a bunch of bugs but also dropped transaction support. It honestly seems like a great idea, but I'm guessing no one at Apple could justify the time spent working on it.

Amazing - much appreciated. How is it going compared to mongo?

Better than MongoDB. Easy to scale up. And no MongoDB gotchas for transaction.

I use my FoundationDb cluster as a MongoDB alternative and a Redis alternative. Only one cluster to maintain and two types of functionality! I have tried setting up and maintaining clusters of MongoDB and Redis in the past and it was horribly complicated. FoundationDB cluster is so much easier to setup and maintain. And it gives me functionality of both Redis KV and MongoDB .

I can see MongoDB. How did you find the performance of running FDB as a Redis alternative vs actual Redis?
