> Key: MESOS-645
> URL: https://issues.apache.org/jira/browse/MESOS-645
> Project: Mesos
> Issue Type: Sub-task
> Reporter: Jie Yu
> Assignee: Jie Yu
> Priority: Minor
> Fix For: 0.15.0

>
> Future is performance critical. The current implementation of Future uses a
> Latch which leverages a process which is not efficient (e.g. user level
> switches, process creation/termination cost, etc.).
> Our idea is to create the Latch in each Future lazily so that in common
> cases, we don't need to create a Latch.
