I am trying to optimize my code and I have a problem that I do not quite understand. A list of notifications similar to the new Facebook ticker will appear on every page of my web application. Thus, for each request, I run this code at the beginning:
notification_query = db.Query(Ticker, keys_only=True)\
.filter('friends =',self.current_user.key().name())
self._notifications_future = notification_query.run()
Then when I find a good place, I call the middle function, which:
notification_keys = [future.parent() for future in self._notifications_future]
self._notifications = db.get_async(notification_keys)
Finally, I pulled them all out at the end:
context.update({'notifications': self._notifications.get_result() })
Everything works fine except for this: if I call the middle function at the end of the query function, I get the following:
Dull spot
And if I name it in what I think is an optimized place, I get the following:
Smart spot
As you can see, the use of the API doubles, making this "optimization". What's going on here?
