NettyServer multi-thread?
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

Hi Yang,
That's correct. The NettyServer constructor uses
Executors.newCachedThreadPool() to create a thread pool for servicing
incoming requests. The Responder can be invoked by multiple threads from
this thread pool, so the Responder should be thread-safe.
