Flow

The Flow connector is used for linking various processors to ensure a sequential flow of data.

If there is no valid flow of data, the flow connector appears with dashed lines. This happens when the flow is unable to read the schema information from its input.

Add Flow

The simple example below connects a DataSource processor to the Result processor. To do so, ensure no processor is selected at the moment. Select the button on the menu bar and click on the DataSource processor. While holding down the mouse, move towards the Result processor. A line will appear from the DataSource processor towards the direction of your mouse. Click onto the Result processor to join the two processors together.

Delete Flow

To remove the Flow connector, simply select the connector and click on the “delete” key on your keyboard. Alternatively, right-click on the connector to display the pop-up menu and select “Delete Graphic” option.
