Class SubtaskState

java.lang.Object

org.apache.flink.runtime.checkpoint.SubtaskState

All Implemented Interfaces:

Serializable

public class SubtaskState
extends Object
implements Serializable

Simple bean to describe the state belonging to a parallel operator. It is part of the TaskState. The state itself is kept in serialized form, since the checkpoint coordinator itself is never looking at it anyways and only sends it back out in case of a recovery. Furthermore, the state may involve user-defined classes that are not accessible without the respective classloader.
