Strategies for managing write queue size in 0.8.2?

[Steve Bate <st...@technoetic.com>]

Hello,

Again, this is version 0.8.2.

I'm currently having a problem with a fast writer and
slower reader causing the writer's memory consumption to
grow rapidly. The memory consumption appears to be caused
by the unbounded write buffer queue in the SocketSession.

What strategies do you recommend to control the writer's
memory usage in these scenarios?

Thanks,

Steve

If you know the average (or maximum) buffer size per message, then you can
calculate the total size of data from IoSession.getScheduledWriteRequests().
So you can delay writing messages considering it.  That's all for now.  For
more accurate calculation, we probably need to add
IoSession.getScheduledWriteBytes() in 0.9 stream.  You can track this issue
here:
