Now that the components have been added on the workspace, they have to be connected together. Components connected together form a subjob. Jobs are composed of one or several subjobs carrying out various processes.

In this example, as the tLogRow and tFileOutputDelimited components are already connected, you only need to connect the tFileInputDelimited to the tLogRow component.

To connect the components together, use either of the following methods:

Right-click and click again

  1. Right-click the source component, tFileInputDelimited in this example.

  2. In the contextual menu that opens, select the type of connection you want to use to link the components, Row > Main in this example.

  3. Click the target component to create the link, tLogRow in this example.

    Note that a black crossed circle is displayed if the target component is not compatible with the link.

    According to the nature and the role of the components you want to link together, several types of link are available. Only the authorized connections are listed in the contextual menu.

Drag and drop

  1. Click the input component, tFileInputDelimited in this example.

  2. When the O icon appears, click it and drag the cursor to the destination component, tLogRow in this example.

    A Row > Main connection is automatically created between the two components.

    While this method requires less operation steps, it works only with these types of Row connections: Main, Lookup, Output, Filter, and Reject, depending on the nature and role of the components you are connecting.

You can also drop components in the middle of a Row link. For more information, see How to add a component between two connected components.
