How to inspect and cancel Celery tasks by task name

Question

I\'m using Celery (3.0.15) with Redis as a broker.

Is there a straightforward way to query the number of tasks with a given name that exist in a Celery queue?

You can do this in one request:

app.control.revoke([
    uuid
    for uuid, _ in
    celery.events.state.State().tasks_by_type(task_name)
])
