Can I bounce an idea off anyone who's interested? I'm looking for an efficient way to get realtime updates to a large-ish number of client apps, and I'm wondering if using App Engine+Google's Talk servers might be the way to do it.
I need to get timely messages to 100-5000 thousand clients, with reasonable (99%?) reliability. I know I can do this with Google Talk at a very small scale - if someone IMs me I'll get the message through Gmail on one computer, iChat on another and Google Talk on my iPhone, all at the same time. But that's just 3 clients on the same account. Could this work at scale? Let's say I create an account - clients-of-kris-12...@gmail.com - and have my all my client apps connect as that user. They're all coded to listen for updates from their buddy - server-of-kris-54...@gmail.com - which is part of my App Engine project. As far as I understand, they'll all hear everything the server is announcing, roughly at the same time. Does anyone know that this would/wouldn't work? And if it would work, does anyone know the billing implications? I'd rather the App Engine team billed me for 5000 messages and were happy to do so, than billed me for one but felt I was abusing the system. (Sorry - I realise this may be more of a Google Talk question than an App Engine question. If anyone wants to point me to a low-level GTalk forum instead, please do!) --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google App Engine" group.
