Subject [jira] [Created] (HBASE-15429) Add a split policy for busy regions
Date Wed, 09 Mar 2016 00:33:40 GMT
Ashu Pachauri created HBASE-15429:

             Summary: Add a split policy for busy regions
                 Key: HBASE-15429
                 URL: https://issues.apache.org/jira/browse/HBASE-15429
             Project: HBase
          Issue Type: Improvement
          Components: regionserver
            Reporter: Ashu Pachauri
            Assignee: Ashu Pachauri
             Fix For: 2.0.0, 1.3.0

Currently, all region split policies are based on size of the region. However, in certain
cases, it is a wise choice to make a split decision based on number of requests to the region
and split busy regions.

A crude metric is that if a region blocks writes often and throws RegionTooBusyExceoption,
it's probably a good idea to split it.
