Elliott Clark commented on HBASE-15429:

My biggest comment is why put all of this in a the table descriptor and not in the config?

> 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.
