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.
