Usage examples of the adapters available here:
This adapter uses a Libmemcached backend to store the cached content:
$di->set('annotations', function ()
{
return new \Phalcon\Annotations\Adapter\Memcached(array(
'lifetime' => 8600,
'host' => 'localhost',
'port' => 11211,
'weight' => 1,
'prefix' => 'prefix.',
));
});
