--------------------------------
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.
