Summary: 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
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.
