E-Commerce Store. The system should be able to receive and provision new orders from a store website. The provisioning process should be able to process all orders, handle payments, as well as process shipments. + +For high availability and high performance, you architect the system using event-driven architecture (EDA), and build microservice apps to handle store frontend, order management, payment processing, and shipment management. You deploy the whole system in a cloud environment. To handle high workloads, you leverage a messaging system to buffer the loads, and scale up multiple instances of microservices. The architecture could look similar to: + +![Workflow Use Case](/images/design-document/workflow-use-case.jpg) + +While each microservice is acting on its own event channels, EventMesh plays a crucial role of doing Event Orchestration. + +We use [CNCF Serverless Workflow](https://serverlessworkflow.io/) to describe this Event Workflow Orchestration. + +## CNCF Serverless Workflow + +CNCF Serverless Workflow defines a vendor-neutral, open-source, and fully community-driven ecosystem for defining and running DSL-based workflows that target the Serverless technology domain. + +Serverless Workflow defines a Domain Specific Language (DSL) to describe stateful and stateless workflow-based orchestrations of serverless functions and microservices. + +More details could be found in its [official github site](https://github.com/serverlessworkflow/specification) + +## EventMesh Workflow + +We leverage Serverless Workflow DSL to describe the EventMesh workflow. Based on its spec, the workflow is consists of a series of workflow states used to describe the control-flow logic. At this time we only support event related workflow states. See the supported states in [Workflow DSL Design](#workflow-dsl-design-wip). + +A `workflow state` can include applicable `actions`, or services/functions that should be invoked during workflow execution. These `actions` can reference reusable `function` definitions which define how these functions/services should be invoked. They can also reference events that trigger event-based service invocations, and events to wait for that denote completion of such event-based service invocation completion. + +In EDA solution, we usually defined our event-driven microservice using AsyncAPI. Serverless workflow `function` definitions support defining invocation semantics using AsyncAPI. See [Using Funtions for AsyncAPI Service](https://github.com/serverlessworkflow/specification/blob/main/specification.md#using-functions-for-async-api-service-invocations) for more information. + +### AsyncAPI + +AsyncAPI is an open source initiative that seeks to improve the current state of Event-Driven Architectures (EDA). +Our long-term goal is to make working with EDAs as easy as it is to work with REST APIs. +That goes from documentation to code generation, discovery to event management. +Most of the processes you apply to your REST APIs nowadays would be applicable to your event-driven/asynchronous APIs too. + +See AsyncAPI detail in the [official site](https://www.asyncapi.com/docs/guides) + +### Workflow Example + +In this example, we build the event-driven workflow of the Order management system above. + +First, we need to define AsyncAPI definitions for our microservice apps. + +- Online Store App + +```yaml +asyncapi: 2.2.0 +info: + title: Online Store application + version: '0.1.0' +channels: + store/order: + subscribe: + operationId: newStoreOrder + message: + $ref : '#/components/NewOrder' + +``` + +- Order Service + +```yaml +asyncapi: 2.2.0 +info: + title: Order Service + version: '0.1.0' +channels: + order/inbound: + publish: + operationId: sendOrder + message: + $ref : '#/components/Order' + order/outbound: + subscribe: + operationId: processedOrder + message: + $ref : '#/components/Order' +``` + +- Payment Service + +```yaml +asyncapi: 2.2.0 +info: + title: Payment Service + version: '0.1.0' +channels: + payment/inbound: + publish: + operationId: sendPayment + message: + $ref : '#/components/OrderPayment' + payment/outbound: + subscribe: + operationId: paymentReceipt + message: + $ref : '#/components/OrderPayment' +``` + +- Shipment Service + +```yaml +asyncapi: 2.2.0 +info: + title: Shipment Service + version: '0.1.0' +channels: + shipment/inbound: + publish: + operationId: sendShipment + message: + $ref : '#/components/OrderShipment' +``` + +Once that is defined, we define the order workflow that describes our Order Management business logic. + +```yaml +id: storeorderworkflow +version: '1.0' +specVersion: '0.8' +name: Store Order Management Workflow +states: + - name: Receive New Order Event + type: event + onEvents: + - eventRefs: + - NewOrderEvent + actions: + - eventRef: + triggerEventRef: OrderServiceSendEvent + resultEventRef: OrderServiceResultEvent + - eventRef: + triggerEventRef: PaymentServiceSendEvent + resultEventRef: PaymentServiceResultEvent + transition: Check Payment Status + - name: Check Payment Status + type: switch + dataConditions: + - name: Payment Successfull + condition: "${ .payment.status == 'success' }" + transition: Send Order Shipment + - name: Payment Denied + condition: "${ .payment.status == 'denied' }" + end: true + defaultCondition: + end: true + - name: Send Order Shipment + type: operation + actions: + - eventRef: + triggerEventRef: ShipmentServiceSendEvent + end: true +events: + - name: NewOrderEvent + source: file://onlineStoreApp.yaml#newStoreOrder + type: asyncapi + kind: consumed + - name: OrderServiceSendEvent + source: file://orderService.yaml#sendOrder + type: asyncapi + kind: produced + - name: OrderServiceResultEvent + source: file://orderService.yaml#processedOrder + type: asyncapi + kind: consumed + - name: PaymentServiceSendEvent + source: file://paymentService.yaml#sendPayment + type: asyncapi + kind: produced + - name: PaymentServiceResultEvent + source: file://paymentService.yaml#paymentReceipt + type: asyncapi + kind: consumed + - name: ShipmentServiceSendEvent + source: file://shipmentService.yaml#sendShipment + type: asyncapi + kind: produced +``` + +The corresponding workflow diagram is the following: + +![Workflow Diagram](/images/design-document/workflow-diagram.png) + +## EventMesh Workflow Engine + +In the following architecture diagram, the EventMesh Catalog, EventMesh Workflow Engine and EventMesh Runtime are running in three different processors. + +![Workflow Architecture](/images/design-document/workflow-architecture.jpg) + +The steps running the workflow is the followings: + +1.
