----------------------------------
[~fanrui] Yes, sampling the metrics is what we have already implemented locally
to introduce this feature.
> Count the read/write/seek/next latency of RocksDB as metrics

> 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.
