Subject Re: Problem with embedded broker
Date Wed, 12 Nov 2014 21:19:28 GMT
That's expected behavior.  By default, brokers only forward messages when
there's a currently-connected consumer somewhere in the network.  If
there's no consumer, the message will hang out on the producing broker,
waiting for the consumer to connect.  When it does connect, the broker that
holds the message will find out about the consumer and forward the message
towards the broker it's connected on.

This makes sense when you think about a more-complicated network of brokers
where a consumer could reconnect to any broker, not just the one it last
connected to; if you forward the message to the last broker the
consumer was on, you might find that it's reconnected to a different broker
somewhere else (maybe even the one the producer is on!), and now you've got
to forward the messages a second time, resulting in wasted network traffic.
