Redis cofiguration for multiple entity managers (symfony 2)

我想在symfony 2中配置redis，以防我定义了2个实体管理器（在config.yml文件中）：

doctrine:
    dbal:
        default_connection: default
        connections:
            default:
                (...connection settings...)
             warehouse:
                (...connection settings...)
    orm:
        auto_generate_proxy_classes: true
        default_entity_manager: default
        entity_managers:
            default:
                connection: default
                auto_mapping: true
                mappings:
                    some_name:
                        type: xml
                        dir: (...dir1...)
                        prefix: (...prefix...)
                        is_bundle: false
            warehouse:
                connection: warehouse
                mappings:
                    some_name:
                        type: xml
                        dir: (...dir1...)
                        prefix: (...prefix...)
                        is_bundle: false

目前，snc-redis 配置为一个实体管理器，默认为：

snc_redis:
    clients:
        default:
            type: predis
            alias: default
            dsn: redis://redis
        doctrine:
            type: predis
            alias: doctrine
            dsn: redis://redis
    doctrine:
        metadata_cache:
            client: doctrine
            entity_manager: default
            document_manager: default
        result_cache:
            client: doctrine
            entity_manager: [default]
        query_cache:
            client: doctrine
            entity_manager: default

如何改变它为多个实体经理服务？我还看到，例如，可以在每个原则 -> orm -> 实体管理器部分中定义 redis：

entity_managers:
    default:
        metadata_cache_driver: redis
        result_cache_driver: redis
        query_cache_driver: redis

相当于在snc_redis->教义部分定义它？
