> 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.
