Appengine LogService has an undocumented quota - u

问题:

Appengine LogService has an undocumented quota: You can make up to a 1,000,000 reads from it per day, and then you'll receive the following error:

Traceback (most recent call last):

OverQuotaError: The API call logservice.Read() required more quota than is available.

Also, when you reach this quota, you'll start see the following on your dashboard (AFAIK you don't see this line there before):

At that point it's not documented at all, and it seems it isn't billable too.

See this too: http://groups.google.com/group/google-appengine/browse_thread/thread/61fac55e1a2d521

Hope it'll save you some time.

Let me know if you can think on a workaround... (just to make it a question ;) )
