Since GAE will create a new instance which would cause latency when there is no one, we'd like to find a method to have an instance which will always be there when we need it.
We use cron + auto scaling just like the method mentioned in the answer here: Google App Engine - automatic-scaling with always on instance?
Our problem is that if we say there is already an instance A which was created by the cron task on GAE. We expect that GAE will use the instance A to handle the following post. However, when there comes a post, GAE will create an instance B and process the following post by instance A. The instance B seems redundant. Since we would like to avoid over the daily quota, is it possible to process the post by instance A if there is not much traffic?
