I'd like to see this tested and documented. I suspect that in some cases, especially where eviction on some pods is disabled, that this would provide a significant price reduction
Agreed. This sounds like a good feature to explore. Obviously, for us to give a recommendation for those that have direct control of their SchedulerConfiguration and the control plane, but also platforms like EKS should explore this alternative option to see if they get increased performance with Karpenter from this other setting.
I suspect that you are right about the performance, at least that we would be able to act more aggressively with consolidation since we'd have "less cluster churn" disrupting our current consolidation decision-making.
