A few answers: 1. Regarding async datastore queries, when you create an iterator, an asynchronous query begins fetching the first batch. As you iterate over the last batch, App Engine will asynchronously start fetching the next batch of results. CPU cost will be the same, but overall end-to-end latencies should decrease
2. Eclipse plugin should be updated by the end of day today. You can also just download the SDK and set the path directly. 3. The Channel API collects many different mechanisms for doing browser push. Long polling is one way, but this is a fallback for older browsers. I believe it *should* be using web sockets when it detects a browser that can support it. -- Ikai Lan Developer Programs Engineer, Google App Engine Blogger: http://googleappengine.blogspot.com Reddit: http://www.reddit.com/r/appengine Twitter: http://twitter.com/app_engine On Fri, Dec 3, 2010 at 9:26 AM, Robert Kluin <robert.kl...@gmail.com> wrote: > I think Keakon is right.
