Hello,

Is anyone aware of a production deployment of an Artemis "cross data center" HA 
cluster? For example, a cluster spread across 3 data centers. Each data center 
contains a master/slave pair.

I would like to know what kind of issues anyone has overcome with such a 
configuration. I understand there are many configuration and operational 
variables. Any info would be helpful.

Note that we are considering asynchronously mirroring each master/slave pair's 
queues to a dedicated asynchronous target node. The asynchronous target node 
would exist in a different data center and would not service any other 
connections. A custom plugin would automatically scale down the messages into a 
live cluster node if the connections to the master/slave mirror sources were 
disconnected for a period of time.

Thank you,
Aaron Steigerwald
