-------------------------------------
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.
