类 CheckpointOptions

java.lang.Object

org.apache.flink.runtime.checkpoint.CheckpointOptions

所有已实现的接口:

Serializable

public class CheckpointOptions
extends Object
implements Serializable

Options for performing the checkpoint. Note that different barriers may have different options.

The CheckpointProperties are related and cover properties that are only relevant at the CheckpointCoordinator. These options are relevant at the AbstractInvokable instances running on task managers.
