How Didi’s Open‑Source Projects Are Shaping Cloud‑Native Innovation at Zhejiang University

On November 3, Didi Open‑Source was invited to Zhejiang University’s School of Software to host the “Source in Zhejiang” sharing session, attracting over a hundred first‑year graduate students.

The event showcased four key projects—enterprise intelligent survey system XIAOJUSURVEY, cloud‑native observability OS HUATUO, high‑performance cross‑platform framework MPX, and cloud‑native Kafka management platform KnowStreaming—highlighting their technical practices and ecosystem impact.

Wang Honghong, Didi Open‑Source operations lead, described the company’s open‑source operating model and community ecosystem, emphasizing safety‑compliant usage, governance, cultural building, and collaboration with universities for talent cultivation.

Zhujunbei presented XIAOJUSURVEY, an enterprise‑grade, AI‑driven survey platform built on a Schema + Logic DSL foundation, offering visual editing, low‑code component extension, cross‑platform consistency via a React Native SDK, and conversational questionnaire generation to boost creation efficiency.

Tu Zengbing discussed HUATUO, a cloud‑native OS‑level observability project leveraging eBPF for low‑overhead kernel data collection, providing automatic tracing of soft‑lockups, OOM, network latency, and integrating multi‑language, full‑stack profiling with Grafana visualizations to shift from reactive to proactive fault prevention.

Xue Gan introduced MPX, a high‑performance cross‑platform framework that compiles a single codebase to multiple mini‑program, H5, iOS, Android, and HarmonyOS targets, featuring template dependency collection, on‑demand loading, multi‑package splitting, and AI‑enhanced development assistance.

Xie Peng explained KnowStreaming, an open‑source Kafka‑based streaming data management platform that offers zero‑intrusion, plug‑in architecture, visual control, multi‑cluster management, and cross‑AZ disaster recovery; the project has garnered over 7,200 Stars and been listed as a trusted open‑source project.

In the interactive discussion, students asked about technical details, contribution processes, community collaboration, and career paths, reflecting strong interest in cutting‑edge technology and open‑source practice, and underscoring the event’s role in promoting open‑source culture and nurturing innovative talent.
