Building Didi’s Core Business Platform with Go: Practices and Open‑Source Contributions
At GopherChina 2018, Didi engineer Shi Songran explained how Go powers the company’s high‑availability order, dispatch, and storage systems, detailing service‑governance practices, two production‑level bugs, and Didi’s open‑source contributions of the gendry database helper and the high‑performance json‑iterator codec.
On April 14‑15, 2018, GopherChina 2018 was held in Shanghai. Among the talks, Didi lecturer Shi Songran presented “Practices of Building Didi’s Core Business Platform with Go”.
The presentation covered four main aspects:
Current scale and usage of Golang in Didi’s business.
Didi’s experience with Go service governance.
Two technical problems encountered in production.
Two open‑source tools contributed by Didi to the Go community.
Shi described how Go is employed in Didi’s order system, dispatch engine, and storage middleware to meet high‑availability, high‑concurrency, and high‑complexity requirements. He then detailed Didi’s service governance practices, focusing on “exception tracing”, “link optimization”, “service refactoring and migration”, and “one‑stop service governance and integration”. The discussion on service refactoring and migration sparked active conversation among attendees.
He also shared two practical issues: a bug caused by a low‑level Go feature and a garbage‑collector optimization experience. The debugging process was demonstrated live, providing valuable insights.
Finally, Shi introduced two open‑source projects from Didi:
gendry – a database operation helper offering connection management, SQL building, and object‑relational mapping.
json‑iterator – a JSON codec that is compatible with the standard Go library but delivers roughly six times higher performance.
Attendees were invited to read the original article to obtain the PPT of the talk. The event marked Didi’s first collaborative project with the Go China community, and Didi expressed its commitment to continue supporting open‑source projects and community activities.
