Sep 1, 20252025-09 Monthly work summary for apache/incubator-devlake: Implemented a fairness fix in pipeline scheduling to prevent high-priority pipelines from starvation, enhancing reliability and SLA adherence for critical workloads. Delivered a priority-aware dequeue that selects the highest-priority ready job and then the earliest runnable among them. This work improves throughput, reduces backlog pressure on high-priority tasks, and strengthens overall CI/CD pipeline robustness.
