> Improve performance of node sorting
> -----------------------------------
>
> Key: YUNIKORN-807
> URL: https://issues.apache.org/jira/browse/YUNIKORN-807
> Project: Apache YuniKorn
> Issue Type: Improvement
> Components: core - scheduler
> Reporter: Craig Condit
> Assignee: Craig Condit
> Priority: Major
> Labels: pull-request-available
> Attachments: Node Sorting Performance Improvement.pdf
>
>
> YuniKorn currently sorts all nodes on demand whenever scheduling of a
> container occurs. This causes significant performance degradation as the
> number of nodes increases.
> If we replace the on-demand sorting with a B-Tree sorted proactively, we can
> improve performance considerably.
> This is a similar approach to YUNIKORN-21, but without the associated
> behavioral changes.
> I've attached a design document with the details of the approach and the
> performance improvement gained.
