Yuan Tian created IOTDB-1321:
--------------------------------
Summary: Filter RowRecord automatically if any column in it is null
Key: IOTDB-1321
URL: https://issues.apache.org/jira/browse/IOTDB-1321
Project: Apache IoTDB
Issue Type: New Feature
Components: Core/Engine
Reporter: Yuan Tian
Currently, IoTDB will join all the sensor value by its time, and if some
sensors don't have values in that timestamp, we will fill it with null.
However, in some analysis scenarios, we only need the row if all the columns of
it have value, so we want the IoTDB to support this feature.
