FerretDB VS MangoDB

if you have postgres, just use https://github.com/FerretDB/FerretDB

FerretDB is an open source document database that adds MongoDB compatibility to other database backends, such as Postgres and SQLite. By using FerretDB, developers can access familiar MongoDB features and tools using the same syntax and commands for many of their use cases.

There is FerretDB. But they are not fully compatible to Mongo yet.

Feature parity progress with apps:

I presume, that after there is feature parity, then someone could run some benchmarks.

Yep that's serious issue and it's similar to our case. Our main product can work just fine even without SSE 4.2 but MongoDB requires it and then indirectly leads to AVX1 support as we use MongoDB as storage. We did PoC with FerretDB last month and I think it may be good option for Gerylog: https://www.ferretdb.io

Shout out to FerretDB, which is an in progress open source re-implementation of MongoDB atop PostgreSQL.

I can't wait to connect Djongo to my MangoDB

This MangoDB project is new, and when looking for it you will see Google still trying to tell you that you made a typo. So this post is a first quick test to validate how it works. Things will probably change with contributions to https://github.com/MangoDB-io/MangoDB

I think you confuse an example with the proxy itself: https://github.com/MangoDB-io/MangoDB
