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.
