Data::ObjectDriver::DrUser:ContData::ObjectDriver::Driver::Cache::Memcached(3)NAMEData::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 ),
),
...

DESCRIPTIONData::ObjectDriver::Driver::Cache::Memcached provides automatic caching
of retrieved objects in your memcached servers, when used in
conjunction with your actual object driver.
USAGE
· Data::ObjectDriver::Driver::Cache::Memcached->new( %params )
Required members of %params are:
· "cache"
The "Cache::Memcached" instance representing your pool of
memcached servers. See Cache::Memcached.
· "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:
· "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.
· "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.
· "MEMCACHED_DELETE ?"
Remove an object from the cache. The argument is the cache key for
the object to invalidate.
· "MEMCACHED_GET ?"
Retrieve an object. The argument is the cache key for the requested
object.
· "MEMCACHED_GET_MULTI ?"
Retrieve a set of objects. The arguments are the cache keys for the
requested objects.
