Can I block on a Google AppEngine Pull Task Queue until a Task is available?

Question

Can I block on a Google AppEngine Pull Task Queue until a Task is available? Or, do I need to poll an empty queue until a task is available?

Answer 1

You need to poll the queue. A typical use case for pull queues is to have multiple backends, each obtaining one thousand tasks at a time.

For use cases where there are no tasks in the queue for hours at a time, push queues can be a better fit.
