Executor thread

[Alex _ <ax...@ameritech.net>]

Hi
how does the executor filterchain work? is each session in its own thread or is each event within a session in its own thread? Or something else? This is for mina 2M3

AW: Executor thread no---signature

Correct me if I'm wrong, but isn't it one of the main features of mina, that I don't have to care (much) about synchronisation?
I couldn't find a documentation about sync in mina on the quick, but I did never see a synchronized block in a IoFilter or IoHandler.

I don't agree with your answer.If there are idle 5 threads in the pool,  2
incoming same session's events will be executed one after another? I think
you have to synchronize the your business logic if it is neccessary.

Hi!

There's a thread pool, which means that there isn't a thread for each session. But the session's events are executed one-after-another, so you don't have to care about synchronzing as long as you stay in a session's context.

Guess you're talking about ExecutorFilter - so yes each protocol message is
delivered up to your handler its own thread taken from the executor's pool
to free processor threads.
