    Description

      We found one of the clusters with read replica enabled always balance lots of replica regions. going through the balancer's cost functions, found that data locality and StoreFileCost have same multiplier for both primary and replica regions. That is something we can improve. Data locality for replica regions should not be a dominant factor for balancer. We can either remove it out of balancer's picture for now and give it a small multiplier.
