This doesn't really happen.
A can consume from node X, and B from node Y, *but* internally to the
cluster both are connected to the master node. That's pretty much what
makes it the master. The reason for this is exactly the concern you
So publishes go to all nodes, consumes just come from the master (which
then informs the slaves so they drop the messages).
