Hi Do you know your key structure and general distribution?
If for instance you keys are ints, you could randomly choose a key do a > query and grab the first past that value or a random number past the first one, that way you only need to return a few keys/entities. To make it more likely to get hits, your could have a task queue that maps the keys ranges, then your random choice can come from a set of values more likely to give you an entity. Just a thought ;-) T On Nov 26, 11:35 pm, lein <[email protected]> wrote: > hello, > > i have a table of questions that has many rows. every now and then i > would have to generate a quiz by randomly selecting questions from > this table. making a key only query and randomly selecting the > question keys from the resulting list of keys, takes a lot of CPU > resources. any suggestions on how i could better do this? > > thanks -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
