Apache Polaris

Apache Polaris is an open-source, cloud-native catalog service for managing Apache Iceberg catalogs. With e6data, Polaris lets you query structured and semi-structured data across cloud data lakes through a unified interface, with support for schema evolution, nested namespaces, and metadata access over the Apache Iceberg REST protocol.

Before you start

• Have your Polaris Host URL ready.
• Have a Client ID and Client Secret for OAuth-based authentication.
• For Serverless workspaces, complete the cloud-specific storage access setup.
• For cross-account configurations, have the relevant cloud identity values ready.
