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.
