Symfony 2 cache Doctrine query results [duplicate]

Answer 1

In doctrine to cache queries or results you can do the following:

private function myQuery()
{
    return $this->connect->createQueryBuilder()
        ->select('user_id')
        ->from('users', 'u')
        ->where('u.user_id = 2')
        ->getQuery()
        ->useQueryCache(true)    // here
        ->useResultCache(true);  // and here
}

Check doc for more info about these methods. This will make your cache driver working - doesn't matter what driver you are using.

To configure Symfony to use specific query driver you need to adjust your settings in config.yml - check this to see complete list of options. What is important in your cache is (this is apc configuration example):

entity_managers:
        some_em:
            query_cache_driver: apc
            metadata_cache_driver: apc
            result_cache_driver: apc
