Jul 1, 2025July 2025 performance summary for apache/dolphinscheduler focused on reliability improvements and developer experience enhancements. Implemented robust termination and cleanup of external processes after task kills, including a timeout-based kill strategy and corrected sudo invocation to prevent unintended termination, ensuring resources are released and task failures don’t leak processes. Augmented Helm deployment guidance with a bilingual (EN/ZH) Helm template debugging guide and automated README updates to improve debugging efficiency and onboarding. Addressed Task-API kill edge cases by adding process-status verification, increasing stability and predictability of task lifecycles. Technologies demonstrated include Kubernetes, Yarn process management, Helm deployments, and cross-language documentation automation.
