Mason Chen commented on FLINK-30833: ------------------------------------ For context, I was writing a connector that depends on closing some metric groups. The closed metric group can be created independently of MetricListener although other tests can continue to use it. [~chesnay] 's described approach makes more sense and I will update the Jira ticket to reflect that. Thanks! > MetricListener supports closing metric groups > --------------------------------------------- > > Key: FLINK-30833 > URL: https://issues.apache.org/jira/browse/FLINK-30833 > Project: Flink > Issue Type: Improvement > Components: Runtime / Metrics, Tests > Affects Versions: 1.16.1 > Reporter: Mason Chen > Priority: Major > > The internal TestingMetricRegistry does not register an action when a metric > group is closed.
