NAME

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

VERSION

       version 0.54

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 { ... });

NAME

       CHI::Driver::Memcached -- Distributed cache via memcached (memory cache daemon)

VERSION

       version 0.14

SYNOPSIS

	   use CHI;

	   my $cache = CHI->new(
	       driver => 'Memcached',	# or 'Memcached::Fast', or 'Memcached::libmemcached'
	       namespace => 'products',
	       servers => [ "10.0.0.15:11211", "10.0.0.15:11212", "/var/sock/memcached",
	       "10.0.0.17:11211", [ "10.0.0.17:11211", 3 ] ],
	       debug => 0,
	       compress_threshold => 10_000,
	   );

DESCRIPTION

       A CHI driver that uses Cache::Memcached to store data in the specified memcached server(s).

       CHI::Driver::Memcached::Fast and CHI::Driver::Memcached::libmemcached are also available as part of this distribution. They work with other
       Memcached clients and support a similar feature set. Documentation for all three modules is presented below.

CONSTRUCTOR OPTIONS

       Namespace, appended with ":", is passed along to the Cached::Memcached::* constructor, along with any constructor options not recognized by
       CHI - for example servers, compress_threshold and debug.

       If you need more control over the options passed to Cache::Memcached::*, you may specify a hash directly in "memd_params".

METHODS

       Besides the standard CHI methods:

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

	       $self->memd->incr("key");
	       my $stats = $self->memd->stats();

UNSUPPORTED METHODS

       These standard CHI methods cannot currently be supported by memcached, chiefly because there is no way to get a list of stored keys.

       dump_as_hash
       clear
       get_keys
       get_namespaces
       is_empty
       purge
