1425456 - Group Taskcluster retriggers requested in short time frame into one action task

Status: RESOLVED DUPLICATE of bug 1510002

(Tree Management :: Treeherder, enhancement, P3)

Description

[Sebastian Hengst [:aryx] (needinfo me if it's about an intermittent or backout)]

Taskcluster plans to switch retriggers to Action tasks (cced Dustin for the bug number of that). To prevent latency due to many retriggers creating a backlog, many retriggers requested in a short time frame should be grouped into one Action task, e.g. only submit the request for the Action task if there have been no more retrigger requests for that push in the last 15 seconds.

Is this to prevent multiple retriggers due to several different people retriggering the same job, or for accidental duplicates by the same person in the same Treeherder tab? If the former, I think this would need to be handled on the Taskcluster side, since the action tasks don't hit the Treeherder backend at all.

It's to convert
 "rrrrrrrrrr"
from ten action tasks with times: 1 into one action task with times: 10.

Ah makes sense now - thank you :-)

Forward duping to bug 1510002 since it has a different approach that might be easier to implement.
