Amazon SageMaker Feature Store Feature Processing supports multiple data sources. The Feature Processor SDK for Python (Boto3) provides constructs to load data from feature groups or objects stored in Amazon S3. In addition, you can author custom data sources to load data from other data sources. For information about Feature Store provided data sources, see [Feature Processor data source Feature Store Python SDK](https://github.com/aws/sagemaker-python-sdk/blob/master/src/sagemaker/feature_store/feature_processor/_data_source.py).
