> - 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.
