CHI::Driver::FastMmap - Persistent interprocess cache via mmap'ed files
version 0.60
use CHI; my $cache = CHI->new( driver => 'FastMmap', root_dir => '/path/to/cache/root', cache_size => '1m' );
This cache driver uses Cache::FastMmap to store data in an mmap'ed file. It is very fast, and can be used to share data between processes on a single host, though not between hosts.
To support namespaces, this driver takes a directory parameter rather than a file, and creates one Cache::FastMMap file for each namespace.
Because CHI handles serialization automatically, we pass the "serializer" flag as ''; and to conform to the CHI API, we pass "unlink_on_exit" as 0, so that all cache files are permanent.
You will need to install Cache::FastMmap from CPAN to use this driver.
Any other constructor options not recognized by CHI are passed along to Cache::FastMmap->new.
