You're absolutely right. But all frameworks have to go through these humps. Hell, I remember just 2 years ago having MongoDB in production it would regularly crash. We got rid of it in production, but I'd reconsider using it now.

Which features, are making you consider MongoDB? I'm asking because I wrote a (really short and small) MongoDB-ish abstraction layer over SQLite the other day (https://github.com/stochastic-technologies/goatfish), and it seems to me that it's trivial to emulate the MongoDB queries and various other features over SQL without all the hassle of it eating your data or requiring 100 GB of RAM for a few indices.
