30 sec execution limitation only to web requests or to all requests ?

[Krishnan Saidapet P. T.]

Hi,

The following from Google App Engine states,

"..Application code only runs in response to a web request, a queued
task, or a scheduled task, and must return response data within 30
seconds in any case. A request handler cannot spawn a sub-process or
execute code after the response has been sent..."

My question being, is 30 sec applicable only for web questions or to
even requests from a queued and scheduled tasks as well ?

Yes, queued tasks and scheduled tasks have an execution time limit as
well. You'll want to break your large tasks into smaller pieces. We've
committed to map/reduce support to help make this easier on our
roadmap for a future release.

Hi Ikai,

Thanks for the reply.

Sure I will architecture my application this way. Is the limit for queued/scheduled tasks also 30 seconds as well or is it some other figure ?

thanks,

I'm sure that part of the reason google has made this decision (besides
just preventing run away tasks) is to encourage building things in such a
way that you can run many independent tasks in parallel.

I wish more people would write software with that sort of thing in mind :)
