It is highly unusual to use NoSQL as the main data store in Django (so much of the built-in functionality requires relational databases, so you end up net-negative). Most Django folks augment their relational database with some NoSQL bits.

We've been big fans of storing core data in Django models, but using things like key/value stores to store random extra bits that aren't exactly core to the model. Redis is great for this, or another model as triple store style GenericRelation if you need to query on it.

I don't imagine the nonrel branch will move again, its such a departure from core Django. Look into using Flask, as there aren't many "mature" frameworks that do NoSQL core.

1.4 is work in progress
