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.
