Summary: 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
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.
