…log access Introduces a new catalog-level privilege CATALOG_READ_DATA (code 103) that grants read-only access to all data and navigational metadata within a specific catalog. This is intended for data analyst principals who need broad read access across an entire catalog without any write or administrative capabilities. CATALOG_READ_DATA subsumes the following privileges when granted on a catalog: - NAMESPACE_LIST and NAMESPACE_READ_PROPERTIES (catalog navigation) - TABLE_LIST, TABLE_READ_PROPERTIES, and TABLE_READ_DATA (table access) - VIEW_LIST and VIEW_READ_PROPERTIES (view access) It is itself subsumed by CATALOG_MANAGE_CONTENT (the existing full-access catalog privilege), preserving the existing privilege hierarchy. Changes: - PolarisPrivilege.java: add CATALOG_READ_DATA enum constant (code 103) - PolarisAuthorizerImpl.java: register subsumption rules in SUPER_PRIVILEGES - polaris-management-service.yml: add CATALOG_READ_DATA to CatalogPrivilege enum - PolarisPrivilegeTest.java: update code-to-privilege mapping test Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

Thanks for your contribution, @Praneeth-Sagar-13 !
The changes LGTM 👍
Still, given this PR affects the Polaris RBAC model, I believe it would be wise for the sake of community awareness to have a "[DISCUSS]" thread for it on the dev ML before merging.
Would you be comfortable starting this email thread (you may want to subscribe to dev too)?
