Su Yichao contributed to the apache/dolphinscheduler repository over eight months, focusing on reliability, security, and developer experience across both backend and frontend layers. He engineered robust task termination and resource cleanup mechanisms, improved workflow state management, and enhanced data integrity by enforcing unique task names. Using Java, TypeScript, and Spring Boot, Su addressed edge-case failures, implemented Kerberos-secured JDBC connectivity, and introduced no-timeout large file uploads. He also improved UI reliability with Vue.js, automated documentation updates, and standardized frontend code quality checks. His work demonstrated depth in process management, error handling, and cross-language integration, resulting in more stable and maintainable workflows.

Nov 1, 2025November 2025 (Month: 2025-11) — Delivered two key features for the Apache DolphinScheduler project, focused on reliability, security, and cloud readiness. 1) No Timeout for Large File Uploads: disabled frontend and API timeout limits to allow large file uploads without interruptions by setting timeout to 0 in resource-related API calls, enhancing reliability and user experience for large files. Commit: dc42bd58c5a1214bbda056f4b5280c6fe6e41af0. 2) Prometheus Endpoint Authentication with Kubernetes Configuration Enhancements: added authentication for the Prometheus endpoint and adapted configuration for Kubernetes deployments to improve security and cloud integration. Commit: d736cc0227a0af01ce8e3a1f8f34589fd9c9ca7a. No major bugs fixed are recorded for this period based on available data.

Oct 1, 2025Month: 2025-10 — Focused on improving data integrity and workflow reliability in apache/dolphinscheduler. Delivered a targeted bug fix to enforce unique task names within workflows, with an accompanying status code for duplicates and service-level validation on save/update. This reduces runtime errors, prevents ambiguous workflows, and improves downstream scheduling/reporting accuracy. The changes are tied to commit b3a40d882f28bbaa2bae3755d6203c2ff0048cc0 and reference issues #17575/#17576.

Aug 1, 2025August 2025 monthly summary for apache/dolphinscheduler focused on UI reliability improvements for run-mode handling. Delivered a targeted bug fix that hides the execution order option for parallel runs and renders it only for SERIAL, aligning frontend behavior with backend run-mode semantics and reducing misconfiguration risk for users running parallel workflows.

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.
