      Description

      We need to add the metrics collection such as cache hits / misses, cache size, dirty key size, etc for the RocksDBStore. However this may need to refactor the RocksDBStore a little bit since currently caching is not exposed to the MeteredKeyValueStore, and it uses an LRUCacheStore as the cache that does not keep the dirty key set.
