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

NAME

       CHI::Benchmarks - Benchmarks of CHI and non-CHI drivers

VERSION

       version 0.54

DESCRIPTION

       These benchmarks were created by running

	  etc/bench/bench.pl -d . -t 10 -x

       for CHI 0.42, on OS X v10.6.6, 2.2 GHz Intel Core 2 Duo, Perl 5.12.2.

       For each cache, bench.pl does repeated gets and sets of a data structure for at least 10 seconds and measures the wallclock time per
       operation.

       These numbers should just be used as a rough guideline! Actual results will vary widely depending on system, get/set pattern, actual values
       being set, the proper tuning of memcached/mysql, etc. For best results run the benchmark script (available in this distribution) on your
       own system.
