> Priority: Minor
>
> [SPARK-22050|https://issues.apache.org/jira/browse/SPARK-22050] give a way to
> log BlockUpdated events. Actually, the ExecutorMetricsUpdates are also very
> useful if it can be persisted for further analysis.
> As a performance reason and actual use case, the PR offers a fraction
> configuration which can sample the events to be persisted. we also refactor
> for BlockUpdated with the same sampling way.
