[jira] [Created] (HBASE-26237) Improve computation complexity for primaryRegionCountSkewCostFunctio

Clara Xiong created HBASE-26237:
-----------------------------------

             Summary: Improve computation complexity for primaryRegionCountSkewCostFunctio
                 Key: HBASE-26237
                 URL: https://issues.apache.org/jira/browse/HBASE-26237
             Project: HBase
          Issue Type: Bug
          Components: Balancer
            Reporter: Clara Xiong


Recomputation of primaryRegionCountSkewCostFunction can be reduced from O(n ) to O(1) by only incrementing the destination and decrementing the source instead of full recompute.
