> Relational databases like SQL Server, Oracle and Sybase provides a way to get
> IO characteristics at query level. We need similar feature with HBase, where,
> when requested, we should be able to get metrics like how many IO's satisfied
> from Block Cache, how many from Bucket Cache and how many ended up in HDFS.
