Wilfred Spiegelenburg commented on YUNIKORN-1928:
-------------------------------------------------
Yes we can look at the making the logic to select pods user quota aware.
Before we do that looking we need to look at the impact that would have. It ups
the complexity of the checks. You would need to track the pods to be marked
unschedulable against the user headroom etc
So before we do that we need to check if that gives us better autoscaling and
how it impacts the performance.
> Exceed queue quota requests should be skipped when cluster auto scaling.
