public ScatteredStateConsumerImpl()

Method Detail

start

public void start()

Overrides:

start in class StateConsumerImpl

onTopologyUpdate

public CompletionStage<CompletionStage<Void>> onTopologyUpdate(CacheTopology cacheTopology,
                                                               boolean isRebalance)

Description copied from interface: StateConsumer

Receive notification of topology changes. StateTransferStartCommand, or ScatteredStateGetKeysCommand for CacheMode.SCATTERED_SYNC, are issued for segments that are new to this member and the segments that are no longer owned are discarded.

Specified by:

onTopologyUpdate in interface StateConsumer

Overrides:

onTopologyUpdate in class StateConsumerImpl

Returns:

completion stage that is completed when the topology update is processed, wrapping another completion stage that is completed when the state transfer has finished

beforeTopologyInstalled

protected void beforeTopologyInstalled(int topologyId,
                                       boolean startRebalance,
                                       ConsistentHash previousWriteCh,
                                       ConsistentHash newWriteCh)

Overrides:

beforeTopologyInstalled in class StateConsumerImpl

handleSegments

protected CompletionStage<Void> handleSegments(boolean startRebalance,
                                               org.infinispan.commons.util.IntSet addedSegments,
                                               org.infinispan.commons.util.IntSet removedSegments)

Overrides:

handleSegments in class StateConsumerImpl

onTaskCompletion

protected void onTaskCompletion(InboundTransferTask inboundTransfer)

Overrides:

onTaskCompletion in class StateConsumerImpl

stopApplyingState

public void stopApplyingState(int topologyId)

Description copied from class: StateConsumerImpl

Stops applying incoming state. Also stops tracking updated keys. Should be called at the end of state transfer or when a ClearCommand is committed during state transfer.

Specified by:

stopApplyingState in interface StateConsumer

Overrides:

stopApplyingState in class StateConsumerImpl

Parameters:

topologyId - Topology id at the end of state transfer

removeStaleData

protected CompletionStage<Void> removeStaleData(org.infinispan.commons.util.IntSet removedSegments)

Overrides:

removeStaleData in class StateConsumerImpl
