When a pipeline is running, data is processed through the connected Snaps.

• In Designer, clicking the Run Pipeline button starts a pipeline's execution.
• In Manager, select Pipelines to run on the Pipeline tab of a project and click the Execute selected pipelines button

As the Pipeline executes, a Snap's color in Designer is updated to reflect its state. 

Pipelines can be configured to be run as scheduled, triggered, or always on. See Tasks for more information.

Using Parameters in a Pipeline

Parameters can be defined for use in a pipeline on the Edit Pipeline properties dialog.

To use the parameter within the pipeline, open the infobox for a Snap that handles expressions and enter _<paramkey> (underscore + parameter Key) as the Expression value.
