Sudhakar,

If you want to distribute messages between queues, you need to use
Consistent Hash exchange [1] type
which is available as a plugin. With RabbitMQ 3.0, you can enable it with

rabbitmq-plugins enable rabbitmq_consistent_hash_exchange

If having multiple consumers on a shared queue is an option, with equal
prefetch levels you will get round
robin delivery to consumers, as demonstrated in [2].

With multiple queues you will get better overall throughput on multicore
machines. With a single shared
queue there is no need to use any plugins.
