Hi > 1) It seems that messages are passed from broker to broker until the message > reaches a final broker where the consumer for that queue has a connection to > it. ie. If we have 5 brokers and all have consumers running. If Broker 1 > sends a message(which is intended for Broker 3) to the queue, could the > message go to broker 2, then to broker 4 and then to broker 3 before it gets > consumed? > The broker will forward the message only to the broker that has consumers for the given queue, so it will be consumed there. So if only broker 3 has an appropriate consumer, the message will not be forwarded to brokers 2 and 4.
