CentralizedCaches.jl exists to solve the problem that you want to cache a whole bunch of stuff, but you also want to develop your code interactively. These means that sometimes you cache the wrong values. So you need a way to flush all your caches in order to start fresh.
It's basically a way to automate the tracking of your caches.
Creating tracked caches is thread-safe, and the tracking does not prevent garbage collection.
We expose a macro that is used to track a cache@new_cache Dict() would create a Dict type cache for example.
By default caches are tracked only by their module, but you can place extra code after to add extra keys,
such as @new_cache IdDict() :solutions would create a cache that is tracked by module and then within that under the key solutions.
Calling clear_all_caches!(MyModule) called empty! on all caches that are tracked which were declared within MyModude.
and clear_all_caches!(MyModule, :solutions) which calls empty! on the subset of these that were also declared with the :solutions key.
You can call clear_all_caches() without specifying any modules at all, but that will clear caches including potentially in other packages you know nothing about, so if (for example) you had that running in a background thread you might break something by emptying a cache you knew nothing about while it is being read from.
Generally you would never all clear_all_caches! in your package code, but rather you would call it manually from the REPL while interactively developing.
