Maxim Khutornenko updated AURORA-1097:
--------------------------------------
Sprint: Twitter Aurora Q1'15 Sprint 4
> Scheduler updater should suppress instance events on resume
> -----------------------------------------------------------
>
> Key: AURORA-1097
> URL: https://issues.apache.org/jira/browse/AURORA-1097
> Project: Aurora
> Issue Type: Task
> Components: Scheduler
> Reporter: Maxim Khutornenko
> Assignee: Maxim Khutornenko
> Priority: Minor
>
> Scheduler updater does not attempt to suppress redundant instance events in
> case an update is paused/blocked and is subsequently resumed/pulsed. This
> leads to a useless sequence of no-op instance events, which may quickly
> consume the allocated event cap (tracked in AURORA-1096).
> For example, an update paused/resumed 2 times after instance 1 is updated
> will generate the following instance sequence:
> 1=[INSTANCE_UPDATING, INSTANCE_UPDATED, INSTANCE_UPDATING, INSTANCE_UPDATED,
> INSTANCE_UPDATING, INSTANCE_UPDATED]
