C++17's std::pmr Comes With a Cost

Feedback form is now closed.
Much has been said regarding the virtues of C++17's new polymorphic allocator
model (std::pmr), but these new facilities come with real costs that
should be considered before their adoption in large codebases. This talk
introduces the polymorphic allocator model and, through example, shows how they
interact with move semantics, unit testing, performance, developer
productivity, and reliability. Finally, concrete recommendations are provided
as to when and how to use 'std::pmr' in your large codebase.

If you're new to 'std::pmr' or allocators in general, this talk should serve as
a solid introduction to both the facility and the issues involved. Those
already familiar will gain deeper insight on the more subtle consequences of
polymorphic allocator use at scale.
