Log:
TEIID-1657: Implemented distributed refreshMatView call based on the JBoss Cache Listener mechanism. When user issues a refreshMatView call on one node, then all the nodes gets notified about the change in the original node after load of the mat view table is finished. The proactive load on the passive nodes are done in a separate thread. Also fixed a memory leak with the TupleBufferCacheLoader in loading batches.
