This software utilizes a memory-mapped file as a shared memory interprocess cache.
The module is easy to use, thanks to its vaguely sane defaults. Creating a new cache with $Cache = Cache::FastMmap->new() and setting or retrieving data with $Cache->set($Key, $Value) or $Cache->get($Key) is straightforward. However, it is worth noting that the $Value parameter must be a reference.
For those who cannot use a reference as the $Value parameter, Cache::FastMmap offers a raw_values option. With $Cache = Cache::FastMmap->new(raw_values => 1), $Value can now be a simple scalar or any other type of value that is not a reference.
Cache::FastMmap is built on a core written in C, so its performance is optimized for speed. The module uses fcntl locking to avoid problems when multiple processes access the cache simultaneously. Moreover, it uses a basic LRU algorithm to manage the cache and ensure that the most frequently used entries are the ones that remain in memory.
In summary, Cache::FastMmap is an essential module for developers who need to speed up their interprocess communication by utilizing a shared memory cache. It is easy to use, highly efficient, and reliable.
