Hi Mauricio, Yes I understand that, and we've been working on it. Sorry that it's taking long.
Hi Wilson, It's coming with the pricing change. Since we started charging with number of instances, we needed to provide more control on how we spin-up a new instances. In other words, if we continued the old behavior, many developers would have complained like "App Engine spins up unnecessary instances.". We believe that it makes more sense when warmup requests are used only for resident idle instances. -- Takashi On Sat, Jul 14, 2012 at 7:18 AM, Wilson MacGyver <wmacgy...@gmail.com>wrote: > any reason behind this change? this seems kind of strange.
