[jboss-jira] [JBoss JIRA] Commented: (JBMESSAGING-1230) Client failover support if one node of a cluster is cleanly shut down.

Tim Fox commented on JBMESSAGING-1230:
--------------------------------------

This is a tricky one.

The problem is that some customers want 

1) Clean shutdown to *not* cause failover - since they don't want all their messages bunching up on one node

But other customers:

2) Clean shutdown to cause failover as expressed in this task.

So if we always have one kind of behaviour (whatever it is) we alienate some users.

Solution seems to me to add an attribute on the post office "enableFailoverOnShutdown" which defaults to false (current behaviour) but if set to true will cause failover to occur when a node is shutdown.

> If one node of a cluster fails in someway, the client will attempt to failover transparently.  However, if one node is shutdown cleanly, the client will not automatically failover to another node in the cluster.  This functionality would be very useful for "rolling upgrades" where a portion of the cluster is left up while the other nodes are being updated.
