Class StreamCoordinator

java.lang.Object

org.apache.cassandra.streaming.StreamCoordinator

public class StreamCoordinator
extends java.lang.Object

StreamCoordinator is a helper class that abstracts away maintaining multiple StreamSession and ProgressInfo instances per peer. This class coordinates multiple SessionStreams per peer in both the outgoing StreamPlan context and on the inbound StreamResultFuture context.
