Inspired by bug 701548.

Does taskcluster have equivalent functionality? If not, this can be wontfixed, since we're moving away from buildapi.

Hey Jonas,
Is part of the roadmap to give various priorities to tasks?

This is useful for pools with limited resources and certain repositories being less important (e.g. try compared to mozilla-central).

Comment 3

[Jonas Finnemann Jensen (:jonasfj)]

We recently introduced task.priority, see:
  http://docs.taskcluster.net/queue/api-docs/#createTask
As evident from docs we have priorities:
  - "normal" (default)
  - "high"

As expected priority "high" is higher than normal :)
And creating a task with it requires the scope "queue:task-priority:high".

You cannot change priority after task submission (technically we could support it).
But I think that it's very powerful to maintain immutability of task definitions,
so I would rather not change that.

But you could retrigger/recreate tasks with higher priority and cancel existing tasks.

---
Our priority levels are strictly discrete, and adding another priority level is expensive in terms of
polling overhead. Preferably 2 priorities should be sufficient, but we could introduce another one.

Thank you for the explanation. Sounds like this bug isn't needed post buildapi (one less thing to clutter up the Treeherder UI \o/) :-)

Thanks jonasfj. This was very helpful. My apologies if I did not go first to the docs.
