Determines whether the Native Object Store (NOS) feature is enabled or disabled.

Field Group

Native Object Store

Valid Settings

Setting Description
TRUE The NOS feature is enabled. Foreign tables can be created in Vantage.
FALSE The NOS feature is disabled. Foreign tables cannot be created in Vantage.
Foreign tables that exist in the database when this field is set to FALSE continue to exist. They can still be queried, and can be dropped.



Changes Take Effect

After the next database restart.

Usage Notes

Foreign tables allow Vantage to access data from external, cloud-based data storage, such as AWS S3, without requiring you to manually move the data into the database first from where it natively resides. Foreign tables are identified by a hostname, path, and other metadata that point to the external storage. Vantage can read and process semi-structured or unstructured external data in foreign tables using standard SQL. For example, you can use Teradata analytic functions to examine the data, join it to the relational data in the database, and issue queries against it as you can for other data in Vantage.
