             Summary: Support ORDER BY DEVICE in align by device query
                 Key: IOTDB-3580
                 URL: https://issues.apache.org/jira/browse/IOTDB-3580
             Project: Apache IoTDB
          Issue Type: New Feature
            Reporter: Yuan Tian


In current mpp and original standalone version, for align by device query, we 
don't hava an order for the result set. Records in one device will be ordered 
by time, but different devices are in a hash order which depends on the 
sequence they are in the iteration of HashMap.

Some users want to order all the devices by their alphabetical order, so we 
need to implement a new syntax like ORDER BY DEVICE.
