Which parameter in the put_dataset_files() method allows you to upload only PDF files?

The correct choice provides a parameter that helps control the behavior of file uploads in a way that ensures only specific types of files are processed. In the context of the put_dataset_files() method, the parameter associated with uploading only PDF files focuses on restricting actions to comply with schema requirements.

Using a parameter that signifies whether to ignore items that do not match the specified schema effectively allows the system to filter the files being uploaded. This means that if the schema is set up to recognize only PDF file formats, using this parameter will ensure that only those files that adhere to the schema will be uploaded, ensuring a cleaner and more accurate dataset.

This approach is integral for maintaining data integrity during inserts and ensuring that the system handles only the appropriate file types, which, in this case, are PDF files. Hence, the ability to manage the upload process based on the schema directly correlates with ensuring compliance to file type requirements.

Understanding how schema validation works in data processing is crucial. It not only allows for streamlined data handling but also mitigates issues arising from incompatible file types, ultimately leading to more robust data management practices.
