I\'m putting several tasks into a task queue and would like to know when the specific tasks are done. I haven\'t found anything in the API about call backs, or checking the stat

    You might be able to accomplish this with the pipeline api. You make something dependent on all 6 tasks and let it rip.

    Good Luck.

    You can use memcache. Use a unique key specific to this task group. Set a count when you kick off your tasks, and have each task atomically decrement it. When the value is 0, your tasks are complete. The task that finds this value to be 0 can call your callback.

    The new REST/JSON task queue API will let you do this.

    http://code.google.com/appengine/docs/python/taskqueue/rest.html

    This does not scale well to thousands of tasks...

    I do like the pipeline API suggestion though!
