Class ConnectionResponse

java.lang.Object

org.apache.nifi.cluster.protocol.ConnectionResponse

public class ConnectionResponse
extends Object

The cluster manager's response to a node's connection request. If the manager has a current copy of the data flow, then it is returned with a node identifier to the node. Otherwise, the manager will provide a "try again in X seconds" response to the node in hopes that a current data flow will be available upon subsequent requests.
