Package org.apache.flink.runtime.io.network

Class ConnectionID

java.lang.Object

org.apache.flink.runtime.io.network.ConnectionID

All Implemented Interfaces:

Serializable

public class ConnectionID
extends Object
implements Serializable

A ConnectionID identifies a connection to a remote task manager by the socket address and a connection index. This allows multiple connections to the same task manager to be distinguished by their connection index.

The connection index is assigned by the IntermediateResult and ensures that it is safe to multiplex multiple data transfers over the same physical TCP connection.
