A logical clustered queue is composed of a set of partial queues one on each node of the cluster.

When a message is sent to a logical queue it is sent to one of the nodes of the cluster and it goes into the partial queue on that node.

If there are local consumers on that node, all well and good, the local consumer will consume the message.

If there are no local consumers, or the local consumer is busy (it's buffer is full), and there are idle consumers on other nodes, then the message can be sent to another (redistributed) so it can be consumed by a different consumer.

That's what we call message redistribution.
