Is it really a good idea to open a dedicated socket for each client if
we have 1000+ clients?
Should not be an issue. Opening sockets is not costly, nor keeping them
opened.
Why is it better (separate sockets)? This scales well or performs well?
You have to do your homeworks here :)
4) otherwise, if you decide to send the data in small chunks, then you
have
to deal with the MessageSent event
Talking about the 4th item, as soon as you wait to be waken up when the
last
chunk has been sent, then the thread will be available for other
sessions.
Yes, but how to issue an asynchronous chunk send request and exit from
handling MessageSent event in IoHandlerAdapter + when chunk
successfully transmitted how to make Mina call again the method which
transfers the data to send the next chunk?
You will have to maintain a session variable which store the current state
of your session. When you receive a request, you prepare the data you want
to send, and split them in small chunks. Then you send the first chunk in
the messageReceived() method, and all the others in the messageSent()
method.
At least, this is how I would do that.
One important feature: does this means that after issuing send (finish
messageReceived event) this thread becomes free and ready for event
for other sessions (returned to thread pool used by Exec Filter or
smth like this)?
Of course.
