CHI::Driver::FastMmap(User Contributed Perl DocumentatCHI::Driver::FastMmap(3)

NAME
       CHI::Driver::FastMmap - Persistent interprocess cache via mmap'ed files

VERSION
       version 0.55

SYNOPSIS
	   use CHI;

	   my $cache = CHI->new(
	       driver	  => 'FastMmap',
	       root_dir	  => '/path/to/cache/root',
	       cache_size => '1m'
	   );

DESCRIPTION
       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
       "raw_values" flag as 1; and to conform to the CHI API, we pass
       "unlink_on_exit" as 0, so that all cache files are permanent.

REQUIREMENTS
       You will need to install Cache::FastMmap from CPAN to use this driver.

CONSTRUCTOR OPTIONS
       root_dir
	   Path to the directory that will contain the share files, one per
	   namespace.  Defaults to a directory called 'chi-driver-fastmmap'
	   under the OS default temp directory (e.g. '/tmp' on UNIX).

       dir_create_mode
	   Permissions mode to use when creating directories. Defaults to
	   0775.

       Any other constructor options not recognized by CHI are passed along to
       Cache::FastMmap->new.

METHODS
       fm_cache
	   Returns a handle to the underlying Cache::FastMmap object. You can
	   use this to call FastMmap-specific methods that are not supported
	   by the general API, e.g.

	       $self->fm_cache->get_and_set("key", sub { ... });
