Michael Park commented on MESOS-7195:
-------------------------------------
[~dzhuk] the above is an outline of why we currently don't have a variadic
template implementation for defer/dispatch currently.
I spoke to [~benjaminhindman] yesterday about changing the API such that few
places where we have overloaded member functions,
the user would be required to pass in a lambda instead. Also, I think the
refactoring work will be easier once we upgrade to C++14.
So here's my proposal:
(1) We move ahead with your patches to get the performance improvements
(2) Upgrade to C++14
(3) Follow-up with the refactoring work
What do you think?
> Use C++11 variadic templates for process::dispatch/defer/delay/async/run

> These methods are currently implemented using {{REPEAT_FROM_TO}} (i.e.,
> {{BOOST_PP_REPEAT_FROM_TO}}):
> {code:title=}
> REPEAT_FROM_TO(1, 11, TEMPLATE, _) // Args A0 -> A9.
> {code}
> This means we have to bump up the number of repetition whenever we have a new
> method with more args.
> Seems like we can replace this with C++11 variadic templates.
