[Answer]-Django GAE cron giving DeadlineExceededError

It’s not a question of just getting GAE to let you complete the function. When developing for App Engine, you do need to think in a slightly different way, precisely because of things like the request deadline. In your case, you need to break the task up into chunks, and process each of those chunks individually.

You don’t say if you’re using django-nonrel with the GAE datastore, or if you’re using Cloud SQL and therefore the standard Django API. If the former, you can use query cursors to keep track of your progress through the Resources. After each chunk, you can use deferred tasks to trigger the next chunk, passing it the cursor so it picks up where the last one left off.
