Producers
From the perspective of producer clients, a routed queue stores messages and forwards them to the home queue. For example, when J sends a message to Q1 on server P, P forwards it to the queue owner, R, which delivers it to Q1 (the home queue).
The message is not available for consumers until it reaches the home queue. That is, client K cannot consume the message directly from server P.
If server R fails, or the route connection from P to R fails, P continues to store messages from K in its queue. When P and R resume communication, P delivers the stored messages to Q1 on R.
Similarly, routed queues do not generate an exception when the maxbytes and maxmsgs limits are exceeded in the routed server. Clients can continue to send messages to the queue after the limit is reached, and the messages will be stored in the routed server until the error condition is cleared.
