Apache Dubbo Component

Java SDK (apache/dubbo)

Dubbo Version

dubbo version 3.3.6 and openjdk17

Steps to reproduce this issue

proto file:

syntax = "proto3";

package xxx.grpc.api;

option java_multiple_files = true;
option java_package = "xxx.grpc.api";
option java_outer_classname = "HelloWorldProto";

service MyService {
  rpc SayHello (HelloRequest) returns (HelloReply) {}
  rpc SayHelloServerStream (HelloRequest) returns (stream HelloReply) {}
  rpc SayHelloClientStream (stream HelloRequest) returns (HelloReply) {}
  rpc SayHelloBiStream (stream HelloRequest) returns (stream HelloReply) {}
}

message HelloRequest {
  string name = 1;
}

message HelloReply {
  string message = 1;
}

Compiling and packaging with grpc-java allows for the use of grpc's backpressure, while compiling with dubbo does not support the following code:

@GrpcService
public class MyServiceImpl extends MyServiceGrpc.MyServiceImplBase {
    @Override
    public StreamObserver<HelloRequest> sayHelloBiStream(StreamObserver<HelloReply> responseObserver) {
        **ServerCallStreamObserver<HelloReply> serverObs = (ServerCallStreamObserver)responseObserver;
        serverObs.disableAutoInboundFlowControl();**
        ........
    }
}
