-------------------------------------------
Summary: Inline preemption filter in PreemptionVictimFilterImpl
Key: AURORA-1894
URL: https://issues.apache.org/jira/browse/AURORA-1894
Project: Aurora
Issue Type: Task
Components: Scheduler
Reporter: Mehrdad Nurolahzade
Priority: Minor
Profiling preemption logic, I can see
{{org.apache.aurora.scheduler.preemptor.PreemptionVictimFilter.PreemptionVictimFilterImpl#preemptionFilter()}}
is producing ~200K/sec lambda objects to be used by
{{filterPreemptionVictims()}}:
{code:title=PreemptionVictimFilterImpl.filterPreemptionVictims()}
FluentIterable<PreemptionVictim> preemptableTasks =
FluentIterable.from(possibleVictims)
.filter(preemptionFilter(pendingTask));
{code}
Inline this logic (refactor to loop) to remove the need to create these
short-lived lambda objects.
