    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.
