Mason Chen commented on FLINK-24574:
------------------------------------
This would enable operators to properly clean up metrics. Here is an example of attempt that would benefit from this: https://github.com/apache/flink/blob/fd01adb87c54abe436ac04d4059a71784762cabd/flink-connectors/flink-connector-kafka/src/main/java/org/apache/flink/connector/kafka/source/metrics/KafkaSourceReaderMetrics.java#L237

> A user asked
> {noformat}
> Suppose I have a short lived process within a UDF that defines metrics. After the process has completed, the underlying resources should be cleaned up. Is there an API to remove/unregister metrics?{noformat}
> There are probably more related use cases, where a metric is only temporarily meaningful.
