Jun 1, 2025June 2025: Delivered a new administrative API capability in cdapio/cdap, introducing an Application Count API for Admin Namespace to enable the Admin dashboard to display the total number of applications per namespace. This provides immediate visibility into namespace usage and supports governance and capacity planning. No major bugs were recorded in this period. The work lays groundwork for future enhancements (e.g., filtering by namespace or other criteria) and demonstrates a durable API design aligned with existing backend services.
