org.axonframework.eventhandling.replay.BackloggingIncomingMessageHandler
IncomingMessageHandler implementation that maintains a backlog of all Events published to a cluster while it is in replay mode. When the replay finishes, events in the backlog are processed. Events that have been replayed will be removed from the backlog, to prevent duplicate publication of events.
When a replay fails, the backlog is cleared. This means backlogged items will not be forwarded to the cluster for handling.
Note that a single BackloggingIncomingMessageHandler should *not* be used for multiple Clusters. Each cluster must have its own instance of BackloggingIncomingMessageHandler. @author Allard Buijze @since 2.0

        // the 0 means we do not need any "intermediate commit" during the replay.
        // The BackloggingIncomingMessageHandler will make sure any events published while replaying are backlogged
        // and postponed until the replay is done.
        ReplayingCluster replayingCluster = new ReplayingCluster(new SimpleCluster("simple"), eventStore,
                                                                 new NoTransactionManager(), 0,
                                                                 new BackloggingIncomingMessageHandler());


        // we initialize an event bus that contains our replaying cluster
        EventBus eventBus = new ClusteringEventBus(new DefaultClusterSelector(replayingCluster));


        // we subscribe our two listeners to the Event Bus
