> Skip scheduling application if too many pods are unschedulable
> --------------------------------------------------------------
>
> Key: YUNIKORN-3115
> URL: https://issues.apache.org/jira/browse/YUNIKORN-3115
> Project: Apache YuniKorn
> Issue Type: Improvement
> Components: core - scheduler
> Reporter: Peter Bacsko
> Assignee: Peter Bacsko
> Priority: Major
> Labels: pull-request-available, release-note
>
> If an application has too many unschedulable pods, it can drastically affect
> scheduling throughput.
> In every cycle, we attempt to schedule all pods. If the app has hundreds or
> thousands of pods on a large cluster, then it can severly limit the overall
> performance of Yunikorn.
> We can just skip the application for a given amount of time (90..300 seconds)
> if a certain number of pods are pending.
> Possible solutions:
> 1. Percentage of pods vs absolute number (eg 25% vs 100)
> 2. Partition-wide config vs queue-level setting
