This endpoint pauses a running PipelineVersion. For a pipeline version using template created for Streaming runtime environment, the pause operation saves a snapshot of the current state of processing. When the pipeline is resumed or upgraded, the pipeline starts from the last saved state. For a pipeline version using template create for Batch runtime environment, the pause operation pauses the future scheduled runs. If a pipeline is currently running then that run will continue until it is successful or failed. For a non scheduled batch pipeline this will return an HTTP status code of 400
