Investigate instrumenting Grpc for service discovery

[okjesse]

Is spring cloud plan to support grpc for a better performance? thanks

[spencergibb]

To support it in what way?

[okjesse]

Now spring cloud use rest for service call service,but the performance is not good enouth,
So i try to use http2 to fix this,but http2 need use https,i found http2+https is not
better than http1+keepalive,so do you have some suggest for service call in spring cloud to
have a better performance like in dubbo? thanks a lot!

So spring cloud instruments rest template with service discovery. We also instrument webclient that does http 2. I think instrumentation for grpc is a good idea.

I also have suggest following:

1. spring boot can support to be a grpc server,like https://github.com/LogNet/grpc-spring-boot-starter
2. gateway can convert http request from web browser to a grpc request,and convert a grpc response to http response to web browser. https://github.com/grpc-ecosystem/grpc-gateway
3. spring cloud security can integration grpc to protect resource server.
4. client call(feign) could support gprc and support load blance like http.

Thanks a lot.

All 4 of those requests belong in different github projects

1. https://github.com/spring-projects/spring-boot/issues
2. https://github.com/spring-cloud/spring-cloud-gateway/issues (already an issue for binary gateway)
3. https://github.com/spring-cloud/spring-cloud-security/issues
4. https://github.com/spring-cloud/spring-cloud-openfeign
