Labels: pull-request-available (was: )
> Split level metrics leak the closed metricGroup on split finish
> ---------------------------------------------------------------

> Key: FLINK-40549
> URL: https://issues.apache.org/jira/browse/FLINK-40549
> Project: Flink
> Issue Type: Bug
> Reporter: Efrat Levitan
> Priority: Major
> Labels: pull-request-available
>
> Today there's no API to deregister child metric groups added via
> {{{}MetricGroup#addGroup{}}}. This is not a problem as long as child metric
> groups are permanent through parent lifecycle.
> For split level metric group this is a problem because they might not live as
> long as the source (aka splitFinished). As a result we are left with a closed
> child metric group reference on the parent, preventing the object GC.
