Imagine you have designated a powerfull hardware box for your messaging system only - the master node. Just to ensure that when something goes wrong with this box you want your clients still to be able to send messages you are running a cluster. And you have no enough money to buy the same kind of box and you get a smaller one - the slave. It is there only for the failover support, so you want all consumers and all producers to use the master node by default.
