Foreign tables enable Vantage to access data in external object storage, such as semi-structured and unstructured data in Amazon S3, Azure Blob storage, and Google Cloud Storage. In-database integration of this data allows data scientists and analysts to read and process this data with Vantage, using standard SQL. You can join external data to relational data in Vantage, and process it using built-in Vantage analytics and functions.

The external data can be in various standard data formats, such as JSON, CSV, and Parquet.

Creating a foreign table requires specifying the location of the data. You must also specify the credentials, except if you are using AWS IAM.

ANSI Compliance

This statement is a Teradata extension to the ANSI SQL:2011 standard.
