-- Stops a pipeline execution.
--
-- __Callback Step__
--
-- A pipeline execution won\'t stop while a callback step is running. When
-- you call @StopPipelineExecution@ on a pipeline execution with a running
-- callback step, SageMaker Pipelines sends an additional Amazon SQS
-- message to the specified SQS queue. The body of the SQS message contains
-- a \"Status\" field which is set to \"Stopping\".
--
-- You should add logic to your Amazon SQS message consumer to take any
-- needed action (for example, resource cleanup) upon receipt of the
-- message followed by a call to @SendPipelineExecutionStepSuccess@ or
-- @SendPipelineExecutionStepFailure@.
--
-- Only when SageMaker Pipelines receives one of these calls will it stop
-- the pipeline execution.
--
-- __Lambda Step__
--
-- A pipeline execution can\'t be stopped while a lambda step is running
-- because the Lambda function invoked by the lambda step can\'t be
-- stopped. If you attempt to stop the execution while the Lambda function
-- is running, the pipeline waits for the Lambda function to finish or
-- until the timeout is hit, whichever occurs first, and then stops. If the
-- Lambda function finishes, the pipeline execution status is @Stopped@. If
-- the timeout is hit the pipeline execution status is @Failed@.
