Duo Zhang created HBASE-25894:
---------------------------------

             Summary: Improve the performance for region load and region count related cost functions
                 Key: HBASE-25894
                 URL: https://issues.apache.org/jira/browse/HBASE-25894
             Project: HBase
          Issue Type: Sub-task
          Components: Balancer, Performance
            Reporter: Duo Zhang
            Assignee: Duo Zhang
             Fix For: 3.0.0-alpha-1, 2.5.0


For a large cluster, we have a lot of regions, so computing the whole cost will be expensive. We should try to remove the unnecessary calculation as much as possible.
