https://developers.sap.com/tutorials/cp-kyma-redis-function.htmlThis sample provides a Redis deployment and two serverless functions that interact with it.这个例子提供了一个 Redis 应用部署和两个使用 Redis 的 serverless 函数。The function cache-order will be set to subscribe to an order.created event provided by the Commerce mock application.Commerce Mock 应用有一个 order.created 事件，cache-order 函数订阅这个事件。Once triggered, the function will perform an API call to the Commerce mock to obtain additional details regarding the order and then cache the information into Redis.一旦 order.created 事件触发，cache-order 函数响应该事件，调用一个 Commerce Mock API，读取创建订单的更多明细，然后将数据存储到 Redis 里。
