How to connect Appwrite to Mongodv

I see in doc https://appwrite.io/docs/databases#collection that we can config connect to Mongodb, but in https://appwrite.io/docs/environment-variables I do not see how to connect to other db beside MariaDB

As of now there is no direct way to connect to mongodb

As of now, there is no support for other DB adapters (as far as i know).

In the future though, you will ideally be able to choose your adapter. I think that's what was mentioned in the docs.

If you want you can upvote this feature request
https://github.com/appwrite/appwrite/issues/909

I think that should be updated into the documentation to highlight that currently it's not supported, but in a future

And just curious, what's the advantage of using mongodb instead of MariaDB?

Or why do you want to use it instead?
