The DoctrineCacheExtensionBundle provides integration of the DoctrineCacheExtension library. DoctrineCacheExtension provides facilities to manage cache managment:

• Default lifetime
• Fetch with a namespace
• Save with a namespace
• Cache invalidation through namespace strategy
• Data collector available in the profiler (not implemented yet)

See OpenClassrooms/DoctrineCacheExtension for more details.

This bundle can be installed using composer:

composer require openclassrooms/doctrine-cache-extension-bundle or by adding the package to the composer.json file directly.

{
    "require": {
        "openclassrooms/doctrine-cache-extension-bundle": "*"
    }
}

After the package has been installed, add the bundle and the DoctrineCacheBundle to the AppKernel.php file:

// in AppKernel::registerBundles()
$bundles = [
    // ...
    new new \Doctrine\Bundle\DoctrineCacheBundle\DoctrineCacheBundle();
    new OpenClassrooms\Bundle\DoctrineCacheExtensionBundle\OpenClassroomsDoctrineCacheExtensionBundle(),
    // ...
)];

# app/config/config.yml

doctrine_cache_extension:
    default_lifetime: 10 #optional, default = 0

To configure the cache providers, use the DoctrineCacheBundle configuration. For example :

# app/config/config.yml

doctrine_cache:
    providers:
        a_cache_provider:
            type: array

$cache = $container->get('doctrine_cache.providers.a_cache_provider');

$cache->fetch($id);
$cache->fetchWithNamespace($id, $namespaceId);
$cache->save($id, $data);
$cache->saveWithNamespace($id, $data, $namespaceId);
$cache->invalidate($namespaceId);

The bundle provides data in the profiler such as number of calls, kind of calls ... (picture)
