MongoDB MultiDB Mode

Registered by Kurt Griffiths on 2013-08-13

The MongoDB driver should be able to hash queues (and messages) to one of N (configurable) databases, rather than putting all queues in a single DB. This mitigates contention with the per-DB global writer lock.

This has been prototyped in Rackspace's Cloud Queues product as a separate blueprint:
