Adding a Table to Stream Operator
Aggregating on delta as a Table causes a change log, producing a single record. The Table to Stream operator morphs the single record back into stream.
- On the Application page, click
and select To Stream 
in the Add Operator pane.
The To_stream node
icon displays in the Graph pane, as well as the properties to be defined in the Operator Settings pane, and the preview of the data in the Schema pane.
The right (outbound) edge allows you to connect to the other operators.
- In the Operator Settings pane, define or select the following required properties:
Property Description Node ID
The ID of the Table to Stream operator.
Inputs
The left input automatically connects to the currently-selected operator. You can select another ID of the operator that will be the source of the data in the Inputs drop-down list. Ideally, this should be an aggregation operator.
The preview of the data (LEFT, RIGHT, and OUTPUT) are displayed in the Schema pane.
The preview of the data (OUTPUT) is displayed in the Schema pane.
NOTE: The data types of the aggregated columns are still unknown. The new data type will be applied once the application is saved.
For example:
- Save the changes.
