             Summary: Consider changing the scheduler library received callback to be a vector/list of events.
                 Key: MESOS-6303
                 URL: https://issues.apache.org/jira/browse/MESOS-6303
             Project: Mesos
          Issue Type: Improvement
            Reporter: Anand Mazumdar


Currently, the {{received}} callback for the Scheduler library 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.
