haosdent commented on MESOS-5038:
---------------------------------
Probably we could continue to use {{collect}}, but add an additional enum
parameter(the name of parameter should be {{mode}}). The default {{mode}} is
{{ALL}} and {{collect}} would wait for all futures. But when we pass {{ANY}} as
mode, {{collect}} would return directly if any of futures complete.
> Added a any mechanism for futures

> Now we already have {{collect}} and {{await}} mechanisms which would wait for
> a list of {{Future}}. However, we would like to return immediately if any of
> the list of {{Future}} complete instead of wait for the whole list finished
> in {{collect}}. The interface of this any mechanism could be
> {code}
> template <typename T>
> Future<T> any(const std::list<Future<T>>& futures);
> {code}
