Yes, this is true. Broker entities (exchanges, queues and bindings)
are maintained in a coherent fashion accross a cluster, but messages
are not. This is due to the cost of replicating messages - it would be
possible to do this, but it is quite expensive and not that many
people really need it (yet). Having said this, it is a subject of
investigation and may appear at some time in the future. Read the
manual for more details: http://www.rabbitmq.com/clustering.html
