Galder Zamarreno commented on JBCACHE-471:
------------------------------------------

This could be somehow related to the resolution of optimistic 
conflicts when merging workspaces.

http://jira.jboss.com/jira/browse/JBCACHE-617

We should probably design both together?

> When JGroups needs to do a merge due to a temporary break in the group structure, JGroups does not handle the merging of data.  This is usually left up to the application to handle.
> JBossCache should support pluggable merge policies, we could provide some simple merge policies and allow users to write their own.
> 1.  Evict on merge policy - when a merge occurs, evict the entire in-memory state.  Useful for Hibernate or when used with a shared cache loader.
> 2.  Other merge algos ... ?
