[jboss-dev-forums] [Design of Clustering on JBoss (Clusters/JBoss)] - Re: Handling cluster state when network partitions occur

[manik.surtani@jboss.com]

Ok, how about:

* Provide a MergeHandler configuration
* Defaults to IgnoreOnMerge, which does nothing.  FlushOnMerge also provided, which flushes in-memory state on merge
* Allows users to write their own MergeHandlers, which are basically called when a MergeView is received.
* Users could also do something similar in a CacheListener's viewChange() callback.

But more important than this, how can an instance tell if there has been a split, and it is not in the primary partition *before* a merge takes place?  E.g., in your example of {A,B,C} and {D,E}, how can instance E decide to shutdown and not process requests?
