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.
