Anand Mazumdar updated MESOS-6303:
----------------------------------
    Description: Currently, the {{received}} callback for the [Scheduler library | https://github.com/apache/mesos/blob/master/include/mesos/scheduler/scheduler.hpp] returns a {{queue}} of events which makes sense semantically. However, this also means that callers have to inherently copy the queue object by value due to looping on all the events and invoking {{pop()}} on the queue (it can't be a const reference). We should consider changing it to {{list}} or {{vector}} to avoid the extra copying if this is a performance bottle-neck.  (was: Currently, the {{received}} callback for the Scheduler library returns a {{queue}} of events which makes sense semantically.
