MongoDB as Persistent

Is your feature request related to a problem? Please describe.
I'm working in a company that heavily uses MongoDB and MongoDB Atlas. So it makes sense for us to run everything through MongoDB as our primary data store specially when it comes to backup / restore, you don't want to have multiple databases.

Describe the solution you'd like
I would say, there is support for casandra and sql databases, it shows there should be some way ( maybe easy way ) to use Atlas as persistent layer.

Describe alternatives you've considered
We are already using python celery in other part of our business services, but we are looking for alternatives and this can help us to move forward with evaluations.

Additional context
Also, we are happy to invest into the project by providing development capacity for this task. Let me know if that could be an option to consider.

No files or tests are named in the issue. Start by comparing the existing Cassandra and SQL database support with the requested MongoDB Atlas persistence layer, especially primary storage and backup/restore. Done requires a defined implementation scope and confirmed MongoDB persistence support suitable for evaluation.
