Memcached Functions for MySQL 0.3 (Default branch)
Memcached Functions for MySQL is a set of MySQLUDFs (user defined functions) to work withmemcached using libmemcached. With these functionsyou get, set, append, prepend, and delete objectsin memcached. You can also use memcached as aglobal sequence generator. With these functionsyou can use triggers to control your object caches.License: BSD License (revised)Changes:
memc_stats() has been added to supply information on memcached server status. memc_stat_get_keys() has been added. Buffering has been added to improve performance.Image

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.
