> 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.
