June 2026 monthly summary for Uber CADENCE repository (uber/cadence). Primary focus this month was enhancing batcher job observability by surfacing real-time metrics directly in the heartbeat data, enabling the UI to display current RPS and Concurrency values and improving monitoring and control of batch processing activities. Changes were validated locally across multiple workflow configurations to ensure accuracy and reliability.

In April 2026, delivered a targeted tooling enhancement to streamline local Cadence server development by introducing a Docker Compose override that runs infrastructure in Docker while the Cadence server runs natively. This change reduces setup friction, accelerates local debugging, and improves reliability of local testing and onboarding for developers working on cadence workflow.

March 2026 was focused on delivering a robust Batch Workflow enhancement in cadence-workflow/cadence, introducing runtime-tunable batch processing via signals and a safe V2 upgrade path. The effort improved operational flexibility, progress safety, and prepare for production-scale batch workloads with minimal disruption to existing callers.

February 2026 (2026-02) focused on stabilizing AdminDeleteWorkflow in the uber/cadence repository, strengthening reliability and operator guidance for deletions touching the database. The changes consolidate fixes, add test coverage, and provide clearer remediation hints to operators, improving overall uptime and data integrity.
