             Summary: Print the actual size of plan when it exceeds the wal_buffer_size
                 Key: IOTDB-1609
                 URL: https://issues.apache.org/jira/browse/IOTDB-1609
             Project: Apache IoTDB
          Issue Type: Improvement
            Reporter: Jialin Qiao


When a plan can not fit into the wal buffer, we throw an exception. However, users do not know how to set the wal_buffer_size.
