I guess the answer is almost surely that Netty would start multiple threads to read the socket channel, just trying to confirm..
when we create a NettyServer, we pass in a Single Responder. if Netty underneath creates many threads , the same responder (and netty handler) will be shared between these threads, so that I have to be careful in the Responder/avro handler implementation, so that it's thread-safe, right? thanks Yang
