Subject [jira] [Created] (HBASE-8715) HBase should support IO QOS
Date Fri, 07 Jun 2013 23:22:20 GMT
Pritam Damania created HBASE-8715:

             Summary: HBase should support IO QOS
                 Key: HBASE-8715
                 URL: https://issues.apache.org/jira/browse/HBASE-8715
             Project: HBase
          Issue Type: New Feature
            Reporter: Pritam Damania
            Priority: Minor

The operating system exposes system calls like ioprio_set/get to set priorities for various
threads doing IO.

HBase can use this to accordingly prioritize operations like flushes/compactions/WAL write
etc to use the disk bandwidth more efficiently.
