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

             Summary: Support different split criteria for consistent hashing index resizing
                 Key: HUDI-4377
                 URL: https://issues.apache.org/jira/browse/HUDI-4377
             Project: Apache Hudi
          Issue Type: New Feature
            Reporter: Yuwei Xiao


Currently, we split at the middle of hash range when splitting hash buckets. This simple strategy may produce un-even children buckets when the data distribution is un-balanced. 

 

A better strategy is to choose a split point which split bucket into a approximated even children buckets.
