Hi ,
I can see the triggers for PME initiation here : https://cwiki.apache.org/confluence/display/IGNITE/%28Partition+Map%29+Exchange+-+under+the+hood Triggers Events which causes exchange Topology events: Node Join (EVT_NODE_JOINED) - new node discovered and joined topology (exchange is done after a node is included into the ring). This event doesn't trigger the PME if a thick client connects the cluster and an Ignite version is 2.8 or later. --> *This means in ignite 2.8 or higher, this is triggered only if nodes that participate in the baseline topology are added ?* Node Left (EVT_NODE_LEFT) - correct shutdown with call ignite.close. This event doesn't trigger the PME in Ignite 2.8 and later versions if a node belonging to an existing baseline topology leaves. --> *This means this is not triggered at all 2.8.1 or higher if shutdown cleanly ? i.e. if this is called : Ignition.stop(false) * Node Failed (EVT_NODE_FAILED) - detected unresponsive node, probably crashed and is considered failed --> *This means this is triggered at all 2.8.1 or higher for baseline nodes or any thick client node ?* Custom events: Activation / Deactivation / Baseline topology set - ChangeGlobalStateMessage Dynamic cache start / Dynamic cache stop - DynamicCacheChangeBatch --> *for the end user , is this invoked when we do ignite.getOrCreate( xx ) and ignite.cache(xx )* Snapshot create / restore - SnapshotDiscoveryMessage Global WAL enable / disable - WalStateAbstractMessage Late affinity assignment - CacheAffinityChangeMessage regards, Veena. -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
