Class ResultPartitionID

java.lang.Object

org.apache.flink.runtime.io.network.partition.ResultPartitionID

All Implemented Interfaces:

Serializable

public final class ResultPartitionID
extends Object
implements Serializable

Runtime identifier of a produced IntermediateResultPartition.

In failure cases the IntermediateResultPartitionID is not enough to uniquely identify a result partition. It needs to be associated with the producing task as well to ensure correct tracking of failed/restarted tasks.
