Perhaps the protocol needs to be extended?
It does seem that it could be useful to be able to move the prefetch
window without having to acknowledge the message.
A further thought here: it would be possible to resize the prefetch
winddow instead of moving it. i.e. if the prefetch is 100 and the
application is in control of when acknowledgements will be sent, then
after passing say the 80th message to the application, we could resize
the window to 180. When the acknowledgement is sent, we can resize it
back to 100.
I'm not saying that is ideal, but it seems like a workaround.
Alternatively if we were able to modify the channel.flow message then
instead of just a simple stop/go flag it could allow the 'position'
prefetch window to be stated (e.g. an unacknowledged messages received
count). (Theres no real reason this has to be put into channel.flow
apart from the fact that it does seem like flow control). That would
obviously require a protocol modification though.
Thoughts?
