[jira] [Created] (HBASE-18194) Feature to get IO characteristics at query level

NITIN VERMA created HBASE-18194:
-----------------------------------

             Summary: Feature to get IO characteristics at query level
                 Key: HBASE-18194
                 URL: https://issues.apache.org/jira/browse/HBASE-18194
             Project: HBase
          Issue Type: New Feature
          Components: regionserver
            Reporter: NITIN VERMA
            Priority: Minor


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.
