[jira] [Created] (IOTDB-5385) Optimize the DataRegion leader calculation policy when ConfigNode leader changes

Jinrui Zhang created IOTDB-5385:
-----------------------------------

             Summary: Optimize the DataRegion leader calculation policy when ConfigNode leader changes
                 Key: IOTDB-5385
                 URL: https://issues.apache.org/jira/browse/IOTDB-5385
             Project: Apache IoTDB
          Issue Type: Improvement
            Reporter: Jinrui Zhang
            Assignee: Gaofei Cao


We found a phenomenon in recent testing.

That is, the leaders of DataRegions will be updated by new elected ConfigNode leader.  It adds unstable risks to our system sometimes and it will be optimized.
