Apache Polaris catalog management involves designing hierarchical structures of catalogs, namespaces, and access controls. This Skill guides you through creating catalogs and namespaces via REST API or Python client, defining role-based access patterns, and validating your architecture against governance requirements across development, staging, and production environments.

Yes. Polaris REST API enables catalog and namespace discovery, allowing you to verify runtime environments, validate existing patterns, and query current configuration. This Skill covers API capability checks and discovery workflows to audit your catalog structure.

Role-based access control in Polaris involves modeling principals, roles, and vended credentials patterns. This Skill teaches you to design access-control structures, assign roles to principals, and plan credential distribution strategies that satisfy security and functional requirements across your data environments.

Yes. Polaris integrates with PyIceberg clients across multiple environments. This Skill covers how to connect PyIceberg to Polaris catalogs, validate client compatibility with your REST API endpoints, and manage catalog governance through Python-based workflows.

Catalogs are top-level containers, namespaces organize tables within catalogs, and roles define access permissions for principals. This Skill distinguishes these hierarchical concepts and shows how to model each layer—from catalog creation through namespace organization to role assignment—for effective governance.
