Yeah, this is one of the things we are considering at the moment. However, if I understand correctly, for MongoDB specifically, you need to be using their enterprise offering to be able to utilize their operator.
Not sure what exactly you meant with this. Are you suggesting that we migrate over to Postgres, or that we can somehow use the Postgres operator with MongoDB? I'm honestly open to switching databases, but I don't think management will be thrilled with the idea (not for now at least).
