类 PendingCheckpointStats

java.lang.Object

org.apache.flink.runtime.checkpoint.AbstractCheckpointStats

org.apache.flink.runtime.checkpoint.PendingCheckpointStats

所有已实现的接口:

Serializable

直接已知子类:

FailedCheckpointStats

public class PendingCheckpointStats
extends AbstractCheckpointStats

Statistics for a pending checkpoint that is still in progress.

This is the starting point for all checkpoint tracking. The life cycle of instances of this class is tightly coupled to a PendingCheckpoint instance, which forwards statistics about acknowledged subtasks via reportSubtaskStats(JobVertexID, SubtaskStateStats).

Depending on whether the PendingCheckpoint is finalized successfully or aborted, we replace ourselves with a CompletedCheckpointStats or FailedCheckpointStats and notify the CheckpointStatsTracker.

The statistics gathered here are all live updated.
