Check doctrine settings in the prod env

When I execute the command php bin/console doctrine:ensure-production-settings

I have this result

query Cache uses a non-persistent cache driver, Doctrine\Common\Cache\ArrayCache.

Can someone explain what is this result and what I have to do?

in Symfony 3.4 (sample)

  1. install php-apcu extension

  2. uncomment lines on config_prod.yml

    doctrine:

    orm:

    metadata_cache_driver: apc

    result_cache_driver: apc

    query_cache_driver: apc

and use it without error

This simply means that you have no persistent cache set up for Doctrine queries. Doctrine uses a cache to convert DQL queries to SQL, so in a production environment it makes sense to cache this and not have to do that same work every time.

See here: http://docs.doctrine-project.org/projects/doctrine-orm/en/latest/reference/caching.html#query-cache

The function that throws the Exception is here: https://github.com/doctrine/doctrine2/blob/2.5/lib/Doctrine/ORM/Configuration.php#L374

and the code looks like this:

if ($queryCacheImpl instanceof ArrayCache) {
    throw ORMException::queryCacheUsesNonPersistentCache($queryCacheImpl);
}

What you should look to do is implement a caching mechanism on your production environment, whether it be APC, Memcache, Redis, etc.
