Every ETL flow needs at least one Input Source. Drag an Input Source command for each input in your ETL flow.

Configuration

An ETL workflow can take one or more Input Source commands. When you add a new Input Source and click the Choose Data Source, a dialog box will appear where you can search for or select a data source from the pull-down list. By default, the entire table will be selected as an input source. You can also write an SQL query to filter the table. The Input Source command will take the name of the data source. To change the data source, click the Edit Data Source button.

Like all ETL commands, you can

• Rename the input source by clicking on the pencil icon

• in the Data tab, you can preview the data that will be sent to the next transformation command in the flow.
