Teradata Open Table Format (OTF) supports OAuth-based authentication when integrating with Apache Polaris and Databricks Unity Catalog.
Apache Polaris
Apache Polaris provides a built-in OAuth service for token-based authentication to access catalog services.
Alternatively, Polaris can be configured to use an external OAuth provider, allowing integration with custom identity solutions.
In OTF, the selected identity provider (IDP) type determines how OAuth tokens are generated and validated for catalog access.
Databricks Unity Catalog
Databricks Unity Catalog includes its own OAuth authentication service for catalog access. Authentication can be configured using:
- Databricks-managed service principals
- Externally managed service principals from a supported IDP
OTF uses the issued OAuth tokens to securely authenticate and interact with the Databricks Unity Catalog.
