Descriptions

I was called to handle a exception, which is
Caused by: io.netty.handler.codec.http2.Http2Exception$StreamException: TotalPendingBytes size overflow for stream: 9
at io.netty.handler.codec.http2.Http2Exception.streamError(Http2Exception.java:151)

I used the triple protocol, and then the flow control intercepted it.

I found that the initialWindowSize of TriHttp2RemoteFlowController is read from the dubbo.rpc.tri.initial-window-size parameter, but the default value is 64KB. However, TripleHttp2Protocol also reads from the environment variable to build Http2Settings, but the nettyServer initWindowSize initialized by TripleHttp2Protocol is 8MB. I now get an error of 64KB in the production environment. I am going to configure it to 1MB, but TripleHttp2Protocol drops from 8MB to 1MB. My question is, why is the value read from an environment variable, the default value of TripleHttp2Protocol is 8MB, but the flow control is only 64KB
