  • Method Details

    • isStateTransferInProgress

      boolean isStateTransferInProgress()

    • onTopologyUpdate

      CompletableFuture<Void> onTopologyUpdate(CacheTopology cacheTopology, boolean isRebalance)
      Receive notification of topology changes. Cancels all outbound transfers to destinations that are no longer members. The other outbound transfers remain unaffected.
      Parameters:
      cacheTopology -
      isRebalance -

    • getTransactionsForSegments

      CompletionStage<List<TransactionInfo>> getTransactionsForSegments(Address destination, int topologyId, org.infinispan.commons.util.IntSet segments)
      Gets the list of transactions that affect keys from the given segments. This is invoked in response to a StateTransferGetTransactionsCommand.
      Parameters:
      destination - the address of the requester
      topologyId - required topology before we can start collecting transactions
      segments - only return transactions affecting these segments
      Returns:
      a CompletionStage that completes with the list transactions and locks for the given segments

    • getClusterListenersToInstall

      Collection<ClusterListenerReplicateCallable<Object,Object>> getClusterListenersToInstall()

    • startOutboundTransfer

      void startOutboundTransfer(Address destination, int topologyId, org.infinispan.commons.util.IntSet segments, boolean applyState)
      Start to send cache entries that belong to the given set of segments. This is invoked in response to a StateTransferStartCommand. If the applyState field is set to false, then upon delivery at the destination the cache entries are processed by a StateReceiver and are not applied to the local cache.
      Parameters:
      destination - the address of the requester
      topologyId -
      segments -
      applyState -

    • cancelOutboundTransfer

      void cancelOutboundTransfer(Address destination, int topologyId, org.infinispan.commons.util.IntSet segments)
      Cancel sending of cache entries that belong to the given set of segments. This is invoked in response to a StateTransferCancelCommand.
      Parameters:
      destination - the address of the requester
      topologyId -
      segments - the segments that we have to cancel transfer for

    • start

      void start()

    • stop

      void stop()
      Cancels all outbound state transfers. This is executed when the cache is shutting down.
