Interesting discussion. � I am new to RabbitMQ and I am trying to<br>
understand the coding and architecture requirements on the Producer side.<br>
<br>
What happens if the Producer cannot push to a queue? �Does that mean<br>
that the Producer system should plan for its own local queue until the<br>
broker is back? �What do you do in production when you do not want to<br>
loose these messages?<br>

That depends on the app and what failure scenarios you are most concerned about.<br>
<br>
Local queues add another moving part that itself can fail.<br>
<br>
<br>
Note that the thread discussed blocked producers. No messages are lost in that situation; message loss would only occur if client or server are terminated/crash or there is a prolonged network disruption.<span class="HOEnZb"><font color="#888888"><br>
