[rabbitmq-discuss] Round robin dispatch between N queues

[Simon MacMullen]

If I understand you correctly you want to have every channel receive 
messages from every queue?

In that case just have every channel issue a basic.consume for every 
queue, and use a lowish prefetch count with basic.qos. Each queue will 
round-robin to each channel that has capacity to consume.

Cheers, Simon
