What would the most performent way to create a thread-safe cache
that can be used across threads/fibers in D? Lock-free as much as
possible.
What I ultimately want to do is to cache some data I pull from a
database (Or elsewhere for that matter) and then cache it
somewhere, so I can avoid having multiple calls to eg. the
database.
Of course I can use an associative array and then put a
synchronize statement around it, but it's not performant and it
can have a huge performance impact when using fibers ex. with
vibe.d since a single connection can end up blocking multiple
connections, just by the fact that single connection is
attempting to access that piece of data.
