Hello all.
I think I'm misunderstanding something fundamental about how the
IoSession.suspendRead() and IoSession.resumeRead() methods work and I would
appreciate any insight you guys can offer.
I have a producer and consumer both based on Mina. What I want to achieve is to
block the producer while the the consumer is still processing the message.
The way I thought I could do this was do something like this in the producer
side:
[...]
WriteFuture wf = ioSession.write(message);
wf.awaitUninterruptibly();
[...]
and in the consumer side:
public void messageReceived(IoSession iosession, Object message) throws
Exception
{
long readMsg = iosession.getReadMessages();
iosession.suspendRead();
[... slow message processing ...]
iosession.resumeRead();
}
I was under the impression that the iosession.suspendRead() would make the
producer block, but this is not the behaviour I'm seeing.
What I'm seeing is that the even with the IoSession in suspend state the
producer manages to successfully write the messages and the
iosession.getReadMessages() in the consumer side keeps getting bigger.
Are my expectations wrong? Is there any way I can achieve the desired behaviour
with Mina?
suspend/resumeRead() is an asynchronous operation. It means message
can be received *after* suspendRead() is called. However, once
suspension request is processed by SocketIoProcessor, no more message
will be received.
Do we need TrafficFuture or something similar for more fine-grained control?
