[jira] [Created] (IOTDB-3488) Support show region query

Jialin Qiao created IOTDB-3488:
----------------------------------

             Summary: Support show region query
                 Key: IOTDB-3488
                 URL: https://issues.apache.org/jira/browse/IOTDB-3488
             Project: Apache IoTDB
          Issue Type: New Feature
            Reporter: Jialin Qiao


For many reasons, we need to get the Region distribution.

 

(1) To see if the region migration is successful when removing a datanode

(2) To see if the region is well-distributed in datanodes

 

So, we could use a SQL to achieve this: show region

 

The query result could contain 5 columns:

RegionID, RegionType, DataNodeID, RPCAddress, RPCPort
