Nobody can help me? To resume, in the cluster each node must process the event from the changes made on the cache. So, each node is symetric and must do a specific action on each event. The problem is that the node that modify the cache get the event but the predata and the postdata are the same and then the difference is null. How can I handle this event in a symetric way? And why the predata and the postdata are the same whereas the changes should be only available after commit, no? Regards.
