    __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 ),

Overview

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.
