# Data::ObjectDriver::Driver::Cache::Memcached(3pm)

object driver for caching objects with memcached

## 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

- •

  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.
