Bill Farner updated AURORA-848:
-------------------------------
Sprint: Aurora Q4 Sprint 1
> Handle resourceOffers callback asynchronously
> ---------------------------------------------
>
> Key: AURORA-848
> URL: https://issues.apache.org/jira/browse/AURORA-848
> Project: Aurora
> Issue Type: Story
> Components: Scheduler
> Reporter: Bill Farner
> Assignee: Zameer Manji
> Priority: Critical
>
> Since the mesos driver synchronizes all callbacks, it's very important to
> return as quickly as possible to avoid blocking other callbacks. In the case
> of {{resourceOffers}}, we start by calling {{storage.write}}, which will
> stall if the write lock is held. In very large, busy clusters, we've
> observed {{resourceOffers}} routinely taking > 1 second, which can lead to
> delays in receiving status updates.
> I suggest the entire body of {{resourceOffers}} be asynchronous to prevent it
> from backing up status updates.
