Offset doesn't fetch data - it does an index scan. Going to the 10,000th

I just realized how confusing this is - we get a list of INDEX keys back.

Hi Dexter,
Lack of global transactions is not a bug, but rather a consequence of having
a distributed datastore. While it's possible to introduce them, it imposes a
large additional overhead, which most users don't want.
For details on one way to implement extended transactions on App Engine,
yea, you are right. It's full of exceptions:

Hi Tim,
I would suggest dividing articles into three categories (for each user):
1) Unread articles
2) Read articles
3) 'Unseen' articles.
The first two can be implemented by means of a 'UserArticle' entity that
represents the read/unread status of an article. I would suggest making them

Thanks Nick!!
So to make sure I understand:
In the last step of your process for getting a list of unread
articles, I'd first get the 'UserArticle' entities marked as Unread,
and I'm assuming each UserArticle entity would contain the key for the
actual article entity. So I'd get the Unread
Have you run AppStats yet? It shouldn't take too long, but tasks do have to
