[jira] [Created] (KAFKA-6498) Add RocksDB statistics via Streams metrics

Guozhang Wang created KAFKA-6498:
------------------------------------

             Summary: Add RocksDB statistics via Streams metrics
                 Key: KAFKA-6498
                 URL: https://issues.apache.org/jira/browse/KAFKA-6498
             Project: Kafka
          Issue Type: Improvement
          Components: metrics, streams
            Reporter: Guozhang Wang


RocksDB's own stats can be programmatically exposed via {{Options.statistics()}} and the JNI `Statistics` has indeed implemented many useful settings already. However these stats are not exposed directly via Streams today and hence for any users who wants to get access to them they have to manually interact with the underlying RocksDB directly, not through Streams.

We should expose such stats via Streams metrics programmatically for users to investigate them without trying to access the rocksDB directly.
