----------------------------------------

             Summary: Optimize precision table Region split policy for AMS
                 Key: AMBARI-13039
                 URL: https://issues.apache.org/jira/browse/AMBARI-13039
             Project: Ambari
          Issue Type: Task
          Components: ambari-metrics
    Affects Versions: 2.1.2
            Reporter: Siddharth Wagle
            Assignee: Siddharth Wagle
            Priority: Critical
             Fix For: 2.1.2


- 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.
