-- Validates the specified pipeline and starts processing pipeline tasks. If the pipeline does not pass validation, activation fails.
--
--
-- If you need to pause the pipeline to investigate an issue with a component, such as a data source or script, call 'DeactivatePipeline' .
--
-- To activate a finished pipeline, modify the end date for the pipeline and then activate it.
