[rabbitmq-discuss] Recommended queue architecture

Fri Dec 20 18:14:36 GMT 2013

Another off the wall idea - create a queue for "message orders
received/completed", publish on the first order "started order id", and
then create a queue for each "order id".  Then you could start up a
listener on that "message orders received/completed" to dynamically start
listeners on the specific "order id" queue and shut it down after the queue
is completed.  Not sure this is really a good idea though
