Topic is an exchange type. Queues can be mirrored, exchanges are *always* mirrored between
all nodes in a cluster.

They should consume from queues that will have messages with specific routing keys
be routed to them.

See http://www.rabbitmq.com/tutorials/amqp-concepts.html if it is still not clear. Message
distribution happens in routing time. Mirroring after messages reach a queue.
