How Didi’s 2018 Open‑Source Surge Shaped the Chinese Tech Landscape
In 2018 Didi expanded its open‑source portfolio to 12 projects, amassed over 16,000 stars and 2,000 forks, contributed more than 300 pull requests, engaged 65 contributors, and delivered dozens of patches to major projects such as Hadoop, Spark, Flink, and Linux, while deepening community partnerships and outlining ambitious open‑source goals for 2019.
2018 Open‑Source Growth
Didi’s open‑source activity exploded in 2018, increasing the number of projects from four in 2017 to twelve. The collective repositories earned more than 16,000 stars, over 2,000 forks, and attracted more than 300 pull requests, with 65 contributors spanning areas like databases, mini‑programs, mobile development, front‑end, architecture, middleware, cloud, and operations monitoring.
Contributions to External Projects
Beyond its own GitHub repositories, Didi submitted 53 patches to well‑known upstream projects such as HDFS, Hive, Spark, Yarn, Flink, and Druid.io, earning one PMC and two Committer roles. The company also contributed to the OpenMessaging community (producing one TSC), led the design and development of RocketMQ’s major improvement RIP‑7, sent 15 patches to the Linux kernel, three to QEMU, five to DPDK, and more than 20 to Ceph, securing one PMC in the Ceph community.
Community Collaboration and Support
Didi became an official member of the Linux Foundation in 2018 and subsequently joined the LFDL, CNCF, and Ceph foundations. In November, it joined the OIN community to help improve patent‑defense mechanisms in core Linux and other OSS technologies. Didi co‑hosted the Gopher China conference with GoCN, sponsored major events such as the China Open Source Conference, Flink Forward, and HBaseCon, and worked with the Chinese Academy of Information and Communications Technology to draft the “Open‑Source License Whitepaper” and an “Enterprise Open‑Source Governance Guide”.
Outlook for 2019
Recognizing open source as the foundation of the internet industry, Didi pledged to continue embracing openness, collaborative win‑wins, and value creation in 2019, aiming to deepen its contributions and work with more community developers to advance China’s open‑source ecosystem.
