Ashu Pachauri updated HBASE-15429:
----------------------------------
Description:
Currently, all region split policies are based on size. 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.
