Here's the thing about the latency. GAE has a serious datastore issue right now. Old records are being returned instead of the most recent ones. It is random. In some cases, they are not returning all the rows for a particular table. We are seeing this behavior in tables which were updated yesterday. I submitted a critical production error documenting these issues with GAE, yesterday.
I was able to get around one of the most serious situations I was having by recopying a namespace, after repeatedly querying to determine the real number of rows -- about half the time GAE was reporting the wrong number of rows. The copied namespace is working ok for now. GAE is not transparent when they have serious issues imo.
