For DataTreeChangeListener, only local events are delivered. For ClusteredDataTreeChangeListener, all events are delivered. DTCLs are delivered to all registrants. A DataTreeChangeListener is only notified once in the cluster, ie only the DTCL on the current leader node. A ClusteredDataTreeChangeListener is notified on every node. _______________________________________________ controller-dev mailing list controller-dev@lists.opendaylight.org <mailto:controller-dev@lists.opendaylight.org> https://lists.opendaylight.org/mailman/listinfo/controller-dev
