July 2025 performance summary for RedHatInsights/insights-rbac. Key capabilities delivered with business value include dynamic RBAC control via feature flags, accelerated data access through caching, and streamlining operations by removing manual certificate management. The RBAC refactor with Unleash enables safer, experiment-driven feature enablement like read-only V2 API mode, with support for ungrouped host IDs and cleaner data handling (reduction of null values). The caching improvement reduces database load and speeds up principal lookups on the /access endpoint. The cleanup of outdated manual certificates reduces maintenance overhead and ensures alignment with automated renewal workflows. Overall, these changes enhance flexibility, reliability, and operational efficiency while maintaining a strong security posture.
