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 involves specifying the location of the data, authentication information required for access to the external storage system, and other information that allows Vantage to identify the data of interest and properly place the data into rows and columns of a Vantage table.
