Hi Joe,

Thanks for you answer ...

Ok, so I guess that I have to rely on a static configuration, and possibly
use an external discovery mechanism to pass around this static information

Question: Assume two brokers B1 and B2 start up; they are configured to
share queues/topics .. At the time that they both start up, they cannot
communicate due to network partitioning ... Now, two clients C1 and C2
connect to the brokers, C1 to B1, and C2 to B2. They both create a topic
"T1" on each broker. Once the network is up and running again and B1 and B2
can communicate again, will the brokers be "smart" enough to merge these two
T1 topic instances, or will B1 and B2 see the two T1 topics as different?
