Alima777 created IOTDB-1520:
-------------------------------

             Summary: Performance optimization of RawQueryDataSetWithValueFilter with limit
                 Key: IOTDB-1520
                 URL: https://issues.apache.org/jira/browse/IOTDB-1520
             Project: Apache IoTDB
          Issue Type: Improvement
            Reporter: Alima777


In order to reduce the number of distributed RPC requests, the original data query with value filtering returns a group of fetchsize data at a time, rather than a single row of data each time. However, if there is a limit limit, it is theoretically unnecessary to continue to query the data after the limit, so it is necessary to introduce the limit into the result set.
