What is a Second Level Cache?
Second Level Cache is a Doctrine's feature added in version 2.5. It allows to cache entity with their associations. More information you can find on Doctrine's website http://docs.doctrine-project.org/projects/doctrine-orm/en/latest/reference/second-level-cache.html
How to configure Second Level Cache in Zend Framework 2/3?
Add following code to Doctrine's configuration file:
'doctrine' => [
'configuration' => [
'orm_default' => [
'metadata_cache' => 'filesystem', // name of cache adapter
'query_cache' => 'filesystem', // name of cache adapter
'result_cache' => 'filesystem', // name of cache adapter
'hydration_cache' => 'filesystem', // name of cache adapter
'second_level_cache' => [
'enabled' => true,
'default_lifetime' => 300,
'default_lock_lifetime' => 300,
'file_lock_region_directory' => __DIR__.'../../data/cache',
]
]
]
]
You can also define regions and lifetime for each of them. Add following array inside second_level_cache
index:
'regions' => [
'my_region_name' => [
'lifetime' => 100,
'lock_lifetime' => 200
],
]
Then, in your entity add:
namespace Application\Entity;
use Doctrine\ORM\Mapping AS ORM;
/**
* @ORM\Entity
* @ORM\Table(name="app_post")
* @ORM\Cache("NONSTRICT_READ_WRITE", region="my_region_name")
*/
class Post
{
/**
* @ORM\Id
* @ORM\Column(type="integer")
* @ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* @ORM\Column(type="string", length=40, nullable=false)
*/
private $title;
}
From now toolbar should show statistics similar to this one on image above.
