Switching to Redis

Replace the default cache implementation with Redis by implementing the CacheItemPoolFactoryInterface to create a Symfony redis adapter.

For an illustration, check our demo component.

Prerequisites

• You have a running Redis server which is accessible from the PHP application.

  For more information, see How to Deploy and Run Redis in a Docker Container.

Procedure

1. Implementation of CacheItemPoolFactoryInterface and using Symfony redis adapter. The key point here is to configure the namespace parameter.

return new RedisAdapter(
    RedisAdapter::createConnection($this->dsn),
    namespace: "cache_items_shop_$shopId",
);

2. In the service YAML file, define the service. In the cache.redis.dsn parameter, use your own Redis server’s DNS.

cache.redis.dsn: 'redis://localhost:6379'

OxidEsales\EshopCommunity\Internal\Framework\Cache\Pool\CacheItemPoolFactoryInterface:
    class: OxidEsales\ComponentTemplate\Cache\RedisCacheItemPoolFactory
    arguments:
        $dsn: '%cache.redis.dsn%'

3. In the root service YAML file of the component, import the new factory service:

imports:
    - { resource: src/Cache/services.yaml }

Result

After the installation of the component, the default filesystem caching is replaced with the new Redis-based caching.
