How does message persistence affect the order of message production by a client and delivery by the JMS server?
Created May 4, 2012
It's convenient to view persistent and nonpersistent messages from the same producing client as elements of a partitioned space, even if sent to the same destination. There is no guarantee that a consuming client will even receive a nonpersistent message; hence, nonpersistent messages must be exempt from any logical conditions on message order in the producing client.
A related issue is that, at best, messages are only ordered within each message-producing session by destination.
