Celery: Callback after task hierarchy

Question

I\'m using Celery from a webapp to start a task hierarchy.

Tasks

I\'m using the following tasks:

• task_a
• task_b

Answer 1

The solution turned out to be the dynamic task feature provided in this pull request: https://github.com/celery/celery/pull/817. With this, each task can return a group of subtasks, which will then replace the original taks in the queue.
