Hi, Glad to say I finally finish generating restful code of Go and Java using open API (well, took me about 2 weeks to learn openapi and go).
When developing a restful framework, we have to write many trivial codes (that will be also written in almost all restful services). So, generating such codes is a good solution as we just need to develop real logic and do not need to care to maintain the generated codes. PR[1] defines several restful APIs for serving Grafana and Prometheus, and uses openapi-generator to generate the source codes of the restful framework in Go and Java. (The generator can also generate client-sdk, but I have not time to try it and we have no requirements). So, just run `mvn generate-sources` in `openapi`' module, and then develop your logic in `openapi/java-rest/src/main/java/org/apache/iotdb/openapi/gen/handler/impl/V1ApiServiceImpl.java` (for java) and`openapi/go-rest/src/iotdbrestimpl/api_service_impl.go` (for Go). The only 3 things should to know are, 1. current openapi-generator has some bug for go-server codes, (I have reported the bug to openapi-generator project), and I have written how to fix it manually in go-rest/README.md 2. current openapi-generator can not generate java codes using native Netty. But it seems developing such a generator is not easy for openapi-generator. 3. I copy some generated codes to src folder. The author of PR #2400 [3] can consider using the generated Go-server codes. (or, do some experiments to check whether the generated codes have an acceptable performance).
