Guozhang Wang resolved KAFKA-6820.
----------------------------------
Resolution: Fixed
> Improve on StreamsMetrics Public APIs
> -------------------------------------
>
> Key: KAFKA-6820
> URL: https://issues.apache.org/jira/browse/KAFKA-6820
> Project: Kafka
> Issue Type: Improvement
> Components: streams
> Reporter: Guozhang Wang
> Priority: Major
> Labels: needs-kip
>
> Our current `addLatencyAndThroughputSensor`, `addThroughputSensor` are not
> very well designed and hence not very user friendly to people to add their
> customized sensors. We could consider improving on this feature. Some related
> things to consider:
> 1. Our internal built-in metrics should be independent on these public APIs
> which are for user customized sensor only. See KAFKA-6819 for related
> description.
> 2. We could enforce the scopeName possible values, and well document on the
> sensor hierarchies that would be incurred from the function calls. In this
> way the library can help closing user's sensors automatically when the
> corresponding scope (store, task, thread, etc) is being de-constructed.
