Jie Yu updated MESOS-645:
-------------------------
Description:
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.
was:
Latch is performance critical as it is used in each Future instance. The
current implementation of Latch leverages a process which is not efficient
(e.g. user level switches, process creation/termination cost, etc.).
Plan to re-implement Latch using Gate.
> Improve the performance of Future.
