Proxy design query
Hi All,
Am implementing a proxy like system that has 2 connectors (taking on one end
and transferring onto the other).
what i basically do in the MessageReceived routine of connector1 is call the
IoSession.write of connector2 and that in turn invokes the ProtocolDecoder
(yes am using a Protocol filter on both connectors). If am expected to
handle lot of messages on connector1, would a straightforward
IoSesssion.write() be sufficient or its better to have a Queue that would
have all the incoming requests and then i read the requests on a separate
thread and call connector2's IoSession ?

Yes i do buffer the data before processing it. Thanks for your suggestion,
i'll check both of them out. one at a time :)

I don't think I would, although it depends on the protocol and data.
If it makes sense to buffer up the data, you might want to use a
protocol encoder/decoder, then take the data and send it. You can try
with and without the queueing, but I bet you find better performance
with not queueing.

The adjuration to be "normal" seems shockingly repellent to me; I see
neither hope nor comfort in sinking to that low level. I think it is
ignorance that makes people think of abnormality only with horror and
allows them to remain undismayed at the proximity of "normal" to
average and mediocre. For surely anyone who achieves anything is,
essentially, abnormal.

Re: Proxy design query

actually i create a new connection on connector2 when i need to send
something.
(i create a new instance of a class that would handle the connection for
connector2 .. which invokes connect() in its constructor; and when it
receives the response it closes the session)
So you think its not necessary to use any queuing ?

Re: Proxy design query
Posted by Mark <el...@gmail.com>.
So you have data coming in on connector 1 and going out connector 2,
do you want connector 2 to always be the same instance? If so, then
you might need some type of queue in order to use the same connection.
Otherwise, I am not sure why you would need a queue.

Yes i did take a look at the proxy example and what i implemented is also
similar to that.
I have the following understanding of how Mina handles the request, please
correct me if am wrong.
The execution for each new message coming on one connector till it is
written onto the other connector happens in a single thread. (i tried
printing the name of the thread in all these routines and noticed same
name). and if another message comes during this period, another thread is
being created.

The adjuration to be "normal" seems shockingly repellent to me; I see
neither hope nor comfort in sinking to that low level. I think it is
ignorance that makes people think of abnormality only with horror and
allows them to remain undismayed at the proximity of "normal" to
average and mediocre. For surely anyone who achieves anything is,
