OK，this is what I wanna know. And 8.4.0 version not support javaagent using HTTP either?

As our company use skywalking but grpc not stable in some situation. So I wanna change the grpc to http.
If it's just performance, and our flow is low as 10k/s.
Should I change the agent to use http?
Is it necessary for safety and stability for me to do so？

@lijial if you mean to send the data in Java agent with HTTP, it's not supported, for Java agent, we only support gRPC.
The OAP backend can receive HTTP data because some languages are hard to use gRPC, Nginx Lua for example

I don't know what do you mean grpc is not stable. But from my understanding, it is really widely adopted. You could change the codes by yourself, for stability, that depends on your codes only.

Deal wu-sheng, Thanks for reply , as this question I should not understand your answer,
As I use 8.4.0 , I can use http? And you support to use http?
Are there still several kind of agent ?

You are not following the latest, it is back, but we only recommend for the languages don't support grpc.
> Is the reason only grpc performance better?
Yes, much much better than JSON based HTTP.
> Now can I use http to send tracedata? is there any worse situation from HTTP?
Send, I don't know, that depends on the agent or SDK. As OAP server, we support that.

OK，I know, thankyou
And is there SPI interface in javaagent, Easy for me to extend data transmission using http?
