Enclosing class:

IntegrationTestRegionReplicaReplication

public static class IntegrationTestRegionReplicaReplication.DelayingMultiThreadedWriter
extends MultiThreadedWriter

This extends MultiThreadedWriter to add a configurable delay to the keys written by the writer threads to become available to the MultiThradedReader threads. We add this delay because of the async nature of the wal replication to region replicas.
