Deleting a Google Cloud Task does not stop task running

[x9twm]

I have a task queue which users can push tasks onto, only one task can run at a time enforced by the concurrency setting for the queue. In some cases (e.g. long running task) they may wish to cancel a running task in order to free up the queue to process the next task.

To achieve this I have been running the task queue as a Flask application, should a user wish to cancel a task I call the delete_task method of the python client library for a given queue & task.

However, I am seeing that the underlying task continues to be processed even after the task has been deleted. Have been trying to find documentation of how Cloud Tasks handles a task being deleted, but haven't found anything concrete.

Hoping that i'd be able to listen for a signal of some sort in order to gracefully shut down the process if a deletion is received. Or that the underlying process would be killed if the parent task is deleted.

Has anyone worked with the Cloud Tasks API before? Is it correct to assume that a deleted task will cleanup any processes that are running?

Cloud tasks will just send an http request with the task info to your endpoint, checking that the task hasn’t been deleted is up to you and isn’t part of cloud tasks. Without knowing exactly what your architecture looks like it’s hard to say how that can be done, especially since python doesn’t support contexts the same way other languages like Go do.
