[rabbitmq-discuss] Suggestion - Simple Pub/Sub

Wed Jan 11 17:30:04 GMT 2012

I don't think you will need to create one queue for each (user, topic)
pair.  If you want U1 to see all messages on T1 and T2, then you can
use one queue for U1.  It is ok for a single queue to have multiple
T1, T2, ... keys.
