Allow messages to be replayed back to original broker if there is demand.
(replayWhenNoConsumers="true").
Due to ENTMQ-444 you also want to configure a replayDelay that is high enough so that
any outstanding message acks are passed along the network bridge *before* we start
to replay messages (replayDelay="500"). The value of replayDelay is a bit of a guess but
on a decently fast network 500 msecs should be enough to pass on and process all message acks.
Note: JMS clients that use the failover transport to connect to a broker in the mesh
arbitrarily should consider using an initialReconnectDelay on the failover url that is
higher than replayDelay configured in the broker. E.g.
"failover:(tcp://brokerA:61616,tcp://brokerB:61616)?randomize=true&initialReconnectDelay=700"
This ensures that the demand subscription for this reconnecting consumer is only created
after replayDelay has elapsed.
If its created before, it may lead to the remote broker skipping message dispatch
to the remote broker and those message would seem to be stuck on the broker despite a consumer
being connected via a networked broker.
See ENTMQ-538 for more details.
