With the rise of containerization technology such as docker, k8s, etc, Go language has become popular. Go's coroutine concurrency mechanism makes Go is very suitable for large-scale high-concurrency back-end server program development. The Go language has near C/C++ performance and near python productivity. At Tencent, part of the existing C++ development gradually turned to Go development, and Tars as MIG's widely used RPC framework has now supported C + + / Java / Nodejs, and the combination with Go language has become a general trend. Therefore, in the voice of users, we launched Tarsgo, and we have applied to Tencent map application, application of commercialization of YingYongbao, Internet+ and other projects. This presentation mainly introduces the functional characteristics of Tarsgo, as well as the use cases, and the differences in writing habits of other versions of the Tars language.
