--------------------------------

             Summary: Count the read/write/seek/next latency of RocksDB as metrics
                 Key: FLINK-16444
                 URL: https://issues.apache.org/jira/browse/FLINK-16444
             Project: Flink
          Issue Type: Improvement
          Components: Runtime / State Backends
            Reporter: Yun Tang
             Fix For: 1.11.0


Currently, user cannot know the read/write/seek/next latency of RocksDB, we could add these helpful metrics to know the overall state performance. To not affect the action performance much, we could introduce counter to only record the latency at interval of some actions.
