Longqiang Qi developed core features and stability improvements across apache/dubbo and alibaba/spring-ai-alibaba over four months. He implemented WebSocket support for the Triple protocol in Dubbo, enabling real-time, bidirectional communication with WebSocket clients using Java and gRPC. In Spring AI Alibaba, he introduced graph-driven conversational AI flow management, leveraging graph databases and reactive programming to support dynamic user interactions. Longqiang also enhanced Dubbo’s cache metadata integrity with MD5 validation and addressed a concurrency bug in ThreadlessExecutor, improving thread safety and shutdown reliability. His work demonstrated depth in backend development, distributed systems, and robust configuration management within production environments.
March 2025: Delivered a critical ThreadlessExecutor concurrency fix in apache/dubbo to improve thread coordination and shutdown safety. The change prevents a race where a waiter could be retrieved and unparking triggered after SHUTDOWN was observed, ensuring proper waiter access before unparking and reducing spurious wakeups. This work is linked to commit 3e5216f0e96edc3b92d7e681a61c020072be6dc8 (Fix concurrency problem. (#15210)). This update enhances stability under high concurrency, contributing to more predictable production behavior.
