Adam B updated MESOS-6904:
--------------------------
Priority: Critical (was: Major)
> Perform batching of allocations to reduce allocator queue backlogging.
> ----------------------------------------------------------------------
>
> Key: MESOS-6904
> URL: https://issues.apache.org/jira/browse/MESOS-6904
> Project: Mesos
> Issue Type: Bug
> Components: allocation
> Reporter: Jacob Janco
> Assignee: Jacob Janco
> Priority: Critical
> Labels: allocator
>
> Per MESOS-3157:
> {quote}
> Our deployment environments have a lot of churn, with many short-live
> frameworks that often revive offers. Running the allocator takes a long time
> (from seconds up to minutes).
> In this situation, event-triggered allocation causes the event queue in the
> allocator process to get very long, and the allocator effectively becomes
> unresponsive (eg. a revive offers message takes too long to come to the head
> of the queue).
> {quote}
> To remedy the above scenario, it is proposed to perform batching of the
> enqueued allocation operations so that a single allocation operation can
> satisfy N enqueued allocations. This should reduce the potential for
> backlogging in the allocator. See the discussion
> [here|https://issues.apache.org/jira/browse/MESOS-3157?focusedCommentId=14728377&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-14728377]
> in MESOS-3157.
