The second option sets the feature retrieval specification as an input to the built-in feature retrieval (pipeline) component. It combines that feature retrieval specification with other inputs - for example, the observation data set. It then submits an Azure Machine Learning pipeline (Spark) job, to generate the training data set as output. This option is recommended to make the training pipeline ready for production, for repeated runs. For more details about the built-in feature retrieval (pipeline) component, visit the [feature retrieval component](#built-in-feature-retrieval-component) resource.
