What should you do if you want to stop a running pipeline immediately?

To stop a running pipeline immediately, utilizing the 'kill' option is the most effective action. This option is typically designed to terminate processes or operations that are currently active without waiting for them to naturally complete their execution. When you select this option, it sends a command to halt the pipeline process immediately, allowing for rapid intervention without prolonged delays.

Other approaches like restarting the pipeline, ignoring it until completion, or rebooting the server would not provide an instant stop to the pipeline. Restarting the pipeline may cause it to restart from the beginning or from a specified checkpoint, but it doesn't terminate the current execution right away. Ignoring it leaves the process running until it completes on its own, which is not suitable for immediate intervention. Rebooting the server could disrupt other services and applications and is a much more drastic approach that might not achieve the desired outcome of stopping the specific pipeline in question.
