(1) This tutorial relies on the Commerce mock application to publish events into the Kyma runtime.

(2) bind the Commerce mock application to the dev Namespace

(3) we will create a service instance of the SAP Commerce Cloud - Events.

(4) The service instance will allow for any microservice or lambda function within the dev Namespace to subscribe to these events by defining an event subscription.

借助这个 mock 应用的 service instance，我们可以让 dev 命名空间的任何微服务或者Lambda Function，订阅 service instance 暴露出的事件。

The subscription pairs an event source, the Commerce mock application, and the event type, order.created, to a subscriber.

订阅实际上是一个抽象，包含了事件源，mock 应用，和订阅事件类型。

这个订阅的源代码，用 yaml 文件定义如下：

apiVersion: eventing.kyma-project.io/v1alpha1
kind: Subscription
metadata:
  name: api-mssql-go-event-sub
spec:
  filter:
    filters:
    - eventSource:
        property: source
        type: exact
        value: ""
      eventType:
        property: type
        type: exact
        value: sap.kyma.custom.mp-commerce-mock.order.created.v1
  protocol: ""
  protocolsettings: {}
  sink: http://api-mssql-go.dev.svc.cluster.local:80/orderCodeEvent

在cmd/api/main.go 里，为 /orderCodeEvent 这个 endpoint，注册一个处理函数：ConsumeOrderCode

bind the mock application to the dev Namespace. This process is used to enable the usage of the APIs and events of the mock application to the bounded Namespace.

把 mock 应用绑定到 dev namespace，这样才能让该命名空间的应用，消费这个 mock 应用暴露出的事件。
