Question about IohandlerAdapter
Hi guys, my question: the method messageReceived(IoSession, Object) in the class IoHandlerAdapter executes parallel or sequenciel? I have a client, who send me a lot of messages and the server processes the message in different way. When the server got a message that take a lot of time to process, the method messageReceived(IoSession, Object) will be block? Or the handler received parallel the next message?

Depends. 1) You have many clients (ie, many sessions) the server will process as many messageReceived() as it has IoProcessor. The number of IoProcessor is configurable, and default to number of Core +1. On a Cure 2 DUO, you will have at least 3 IOProcessor, unless you change this number when you created the Accessor. 2) You have one client, which sends many requests 2-a) You have no ExecutorFilter in the chain In this case, the handler will process ever message sequentially. If it takes a while to process a message, all the other will wait. 2-b) You have an ExecurotFilter in the chain This time, each incoming message will be processed by a separate threads.
