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 ),
        ),
        ...
    });

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

•   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.
