Class CheckpointStatsCache

java.lang.Object

org.apache.flink.runtime.webmonitor.handlers.checkpoints.CheckpointStatsCache

public class CheckpointStatsCache
extends Object

A size-based cache of accessed checkpoints for completed and failed checkpoints.

Having this cache in place for accessed stats improves the user experience quite a bit as accessed checkpoint stats stay available and don't expire. For example if you manage to click on the last checkpoint in the history, it is not available via the stats as soon as another checkpoint is triggered. With the cache in place, the checkpoint will still be available for investigation.
