Error handling with connections - Trigger connections are the connections that are triggered based on certain conditions. In this example, the conditions are that a component or subJob is either completed successfully or has errors. The connection in use creates a dependency between Jobs or subJobs, which are triggered one after the other according to the nature of the trigger. It is important to note that no data is handled through these conditions.
