I disagree with the word "never". I am a huge fan of messaging systems and I have a lot of experience with them and also with polling-based solutions. Consider the situation where you have several updates causing diff requests on the same branch. You're only interested in the last change; with a message for each diff request, calculating the diffs in-between is a waste as you will throw them away with subsequent diff processing. If you were to periodically poll, you would see only the most recent change and work with that. This is a slightly contrived example but you get my drift. Basically, there is a trade-off between responsiveness and efficient processing. _______________________________________________ Mailing list: https://launchpad.net/~launchpad-dev Post to : [email protected] Unsubscribe : https://launchpad.net/~launchpad-dev More help : https://help.launchpad.net/ListHelp
