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

       Data::ObjectDriver::Driver::Cache::Memcached - object driver for caching objects with memcached

SYNOPSIS

	   package MyObject;
	   use base qw( Data::ObjectDriver::BaseObject );

	   __PACKAGE__->install_properties({
	       ...
	       driver => Data::ObjectDriver::Driver::Cache::Memcached->new(
		   cache    => Cache::Memcached->new({ servers => @MEMCACHED_SERVERS }),
		   fallback => Data::ObjectDriver::Driver::DBI->new( @$DBI_INFO ),
	       ),
	       ...
	   });

	   1;

DESCRIPTION

       Data::ObjectDriver::Driver::Cache::Memcached provides automatic caching of retrieved objects in your memcached servers, when used in
       conjunction with your actual object driver.

USAGE

       o   Data::ObjectDriver::Driver::Cache::Memcached->new( %params )

	   Required members of %params are:

	   o   "cache"

	       The "Cache::Memcached" instance representing your pool of memcached servers.  See Cache::Memcached.

	   o   "fallback"

	       The "Data::ObjectDriver" object driver from which to request objects that are not found in your memcached servers.

DIAGNOSTICS

       The memcached driver provides integration with the "Data::ObjectDriver" debug and profiling systems. As these systems are designed around
       SQL queries, synthetic queries are logged to represent memcached operations. The operations generated by this driver are:

       o   "MEMCACHED_ADD ?"

	   Put an item in the cache that was not there. The arguments are the cache key for the object and the flattened representation of the
	   object to cache.

       o   "MEMCACHED_SET ?"

	   Put an item in the cache with new member data. The arguments are the cache key for the object and the flattened representation of the
	   object to cache.

       o   "MEMCACHED_DELETE ?"

	   Remove an object from the cache. The argument is the cache key for the object to invalidate.

       o   "MEMCACHED_GET ?"

	   Retrieve an object. The argument is the cache key for the requested object.

       o   "MEMCACHED_GET_MULTI ?"

	   Retrieve a set of objects. The arguments are the cache keys for the requested objects.
