Maxim Khutornenko updated AURORA-1158:
--------------------------------------
Sprint: Twitter Aurora Q1'15 Sprint 4
> Consider finding preemption slots asynchronously
> -------------------------------------------------
>
> Key: AURORA-1158
> URL: https://issues.apache.org/jira/browse/AURORA-1158
> Project: Aurora
> Issue Type: Task
> Components: Scheduler
> Reporter: Maxim Khutornenko
> Assignee: Maxim Khutornenko
>
> The current Preemptor implementation performs synchronous preemption victim
> search. This isn't necessary as resource swap cannot be performed within the
> same scheduling loop due to victims taking time to vacate their premises
> (being killed).
> Consider asynchronous victim search/killing instead. That will move the heavy
> lifting out of the critical scheduling loop and remove "flat" preemptor perf
> tax applied on every failed task scheduling/assignment.
