Workflows

• A workflow is by default a sequential process that has a starting point and one or more endpoints.

• An action is a step that executes pipelines already implemented or any other element that allows orchestrating the execution of the data integration processes.

• A hop in a workflow can conditionally connect actions and determine which action the workflow needs to execute next.

There are two ways to create a workflow.

• File → New → Workflow

Your new workflow is created, and you’ll see the dialog below.

Add and connect actions

Now you are ready to add the first action. Click anywhere in the workflow canvas, the area where you’ll see the image below.

After clicking you will see a dialog:

Just like you did with pipelines, use the search box in this dialog to find the actions you need. Click or use the arrow keys and hit enter to add an action to your workflow.

For now, add a action to your workflow.

Create a hop

Creating a hop is identical to creating a hop in a pipeline:

• shift-drag: while holding down the shift key on your keyboard. Click on an action, while holding down your primary mouse button, drag to the second action. Release the primary mouse button and the shift key.

Save your workflow:

At first, we have the Workflow run configuration session. A Workflow Run Configuration is a metadata object in Apache Hop and defines where the workflow is executed.

Select the ‘local’ workflow runtime configuration that is available by default in your Hop installation and click ‘Launch’.

You’ll now have an execution results pane very similar to the pipeline execution results.
