Symfony Second Level Cache

This example will help you enable Second Level Cache in Symfony with Redis, also there is an example for Doctrine Extensions Translatable and Doctrine Behaviours Translatable.

Libraries we need:

composer require doctrine/doctrine-bundle doctrine/orm snc/redis-bundle predis/predis
