-----------------------------------------
Summary: Hoist the per-ask backoff getter out of tryAllocate
Key: YUNIKORN-3351
URL: https://issues.apache.org/jira/browse/YUNIKORN-3351
Project: Apache YuniKorn
Issue Type: Sub-task
Components: core - scheduler
Reporter: Dale Richardson
Assignee: Dale Richardson
{{Application.tryAllocate}} calls {{sa.queue.GetMaxAppUnschedAskBackoff()}}
inside the loop that walks the application's asks, so a value that is constant
for the whole scheduling cycle is re-fetched — under the queue lock — once per
ask walked.
Hoist it above the loop. The entry guard changes from {{sa.sortedRequests ==
nil}} to
{{len(sa.sortedRequests) == 0}} so the hoisted call still only happens when
there is at least one ask to walk, preserving the existing "not called when
there is no work" property.
