> Improve the upscaling performance for StateAware policy
> -------------------------------------------------------

> Key: YUNIKORN-564
> URL: https://issues.apache.org/jira/browse/YUNIKORN-564
> Project: Apache YuniKorn
> Issue Type: Improvement
> Components: core - scheduler
> Reporter: Weiwei Yang
> Assignee: Weiwei Yang
> Priority: Major
> Labels: pull-request-available
>
> When calculating the outstanding requests that potentially need to trigger
> the upscaling, we use the same sortingApp function that used by the core
> scheduling logic. When the sorting policy is StateAware, this policy filters
> out apps to limit num of apps that can be scheduled at each moment. This is
> designed for the scheduling phase, however, for trigging the upscaling, we do
> not need to filter those apps, as long as the requests can fit into the
> queues' headroom, we should allow them to trigger the upscaling. This will
> optimize the upscaling perf when the StateAware policy is used.
