Review request for Ambari, Dmytro Sen, Mahadev Konar, Myroslav Papirkovskyy, and Sumit Mohanty.
Bugs: AMBARI-13039
https://issues.apache.org/jira/browse/AMBARI-13039
Repository: ambari
Description
-------
- In light of AMBARI-12983, performance would be seen if the precision table can fully utilize the allocated memstore heap.
- With the single table getting most of the high volume reads and all of the high volume writes it is important to define a policy for splitting the Region in order to optimize performance of the scans.
