Redis

Starting with Shopware v6.6.8.0, Redis support has been improved, giving you more flexibility in how you use it in your projects and plugins.

Once you've set up your Redis connections as explained in the Redis configuration guide, you can access them in your code using the following methods:

1. Inject Shopware\Core\Framework\Adapter\Redis\RedisConnectionProvider and retrieve connections by name:

   <service id="MyCustomService">
       <argument type="service" id="Shopware\Core\Framework\Adapter\Redis\RedisConnectionProvider" />
       <argument>%myservice.redis_connection_name%</argument>
   </service>

   class MyCustomService
   { 
       public function __construct (
           private RedisConnectionProvider $redisConnectionProvider,
           string $connectionName,
       ) { }
   
       public function doSomething()
       {
           if ($this->redisConnectionProvider->hasConnection($this->connectionName)) {
               $connection = $this->redisConnectionProvider->getConnection($this->connectionName);
               // use connection
           }
       }
   }

2. Use Shopware\Core\Framework\Adapter\Redis\RedisConnectionProvider as factory to define custom services:

   <service id="my.custom.redis_connection" class="Redis">
       <factory service="Shopware\Core\Framework\Adapter\Redis\RedisConnectionProvider" method="getConnection" />
       <argument>%myservice.redis_connection_name%</argument>
   </service>
   
   <service id="MyCustomService">
       <argument type="service" id="my.custom.redis_connection" />
   </service>

   class MyCustomService
   { 
       public function __construct (
           private Redis $redisConnection,
       ) { }
   
       public function doSomething()
       {
           // use connection
       }
   }

   This approach is especially useful when you want multiple services to share the same Redis connection.

3. Inject connection directly by name:

   <service id="MyCustomService">
       <argument type="service" id="shopware.redis.connection.connection_name" />
   </service>

   Be cautious with this approach! If you change the Redis connection names in your configuration, it will cause container build errors.

Keep in mind that Redis is an optional dependency in Shopware and might not be available in all installations.
