+Teradata READ_NOS feature to transfer data from an AWS Simple Storage Service (S3) to Teradata table.
+READ_NOS is a table operator in Teradata Vantage that allows users to list external files at a specified location.

 Use the :class:`S3ToTeradataOperator <airflow.providers.teradata.transfers.s3_to_teradata>`

+  The current version of ``S3ToTeradataOperator`` does not support accessing AWS S3 with Security Token Service (STS) temporary credentials. Instead, it exclusively supports accessing with long-term credentials.
