public interface GrpcClientRequest<Req,Resp> extends GrpcWriteStream<Req>
You interact with the remote service with gRPC generated messages or protobuf encoded messages.
Before sending a request you need to set #serviceName) and #methodName) or
alternatively the service fullMethodName(java.lang.String).
Writing a request message will send the request to the service:
#end(Req)#write(Req) any time you need and then WriteStream.end()| Modifier and Type | Method and Description |

WriteStreammaxSize. You will still be able to write to the stream even
if there is more than maxSize items in the write queue. This is used as an indicator by classes such as
Pipe to provide flow control.
The value is defined by the implementation of the stream, e.g in bytes for a

The stream implementation defines when the drain handler, for example it could be when the queue size has been
reduced to maxSize / 2.
