[google-appengine] Re: How much time to give for each db query in order not to occur DeadlineExceededError
I see, it seems to be the best solution right now:) thanks On Dec 23, 2:28 am, Marzia Niccolai ma...@google.com wrote: Hi, It's difficult to estimate the amount of time it takes to put() and delete() datastore entities because it depends a great deal on the size and shape of your entities. One thing you should do is call db.Put(entities) in one call, instead of multiple calls in one request to entity.put(). Also, you can't rely on the speed of the dev_appserver to be indicative of the speed on App Engine itself. The best advice I can give is, if you see the datastore is constantly timing out on a given request, reduce the number of entity updates in that request until you find the number that best fits your data. -Marzia On Sat, Dec 20, 2008 at 6:19 PM, Bob bobzs...@gmail.com wrote: Hi GAE team, how about the time for deleting?
