> 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.
