ArmeriaRetrofitBuilder & HTTP2 - Max Number of Streams

Hi,

I’m using the ArmeriaRetrofitBuilder to wrap an HTTP2 REST API call asynchronous:

Retrofit retrofit = new ArmeriaRetrofitBuilder()
        .baseUrl(url)
        .addConverterFactory(JacksonConverterFactory.create(mapper))
        .addCallAdapterFactory(Java8CallAdapterFactory.create())
        .build();

SomeService service = retrofit.create(SomeService.class);
Call<String> sayHello = server.sayHello();
sayHello.enqueue(this);

But I am getting this error:

io.netty.handler.codec.http2.Http2Exception$StreamException: Maximum active streams violated for this endpoint.

Am I using something wrong? If not, how do I set the max number of active streams?

Thanks

I would like to have a way of bounding the number of connections a client makes too. I don’t know what should happen in the case of hitting the max stream AND max connections. Maybe just block the client?

#1481 fixes this issue by making Armeria client respect MAX_CONCURRENT_STREAMS. We do not limit the number of connections yet though. We could take care of it in a separate issue.
