[jira] [Created] (IOTDB-950) Increases the limit on the size of the returned result set

DaweiLiu created IOTDB-950:
------------------------------

             Summary: Increases the limit on the size of the returned result set
                 Key: IOTDB-950
                 URL: https://issues.apache.org/jira/browse/IOTDB-950
             Project: Apache IoTDB
          Issue Type: Improvement
          Components: JDBC
            Reporter: DaweiLiu


The current connection between JDBC and Server ues 'TFastFramedTransport', which DEFAULT_MAX_LENGTH=16M.

Usually the request results are not that large, but when you have a very large number of columns(eg. 2 million columns), you will exceed this limit, making it impossible to show the results you need to query.
