Event Sourcing Workflow Pattern

[joshanir]

To submit a workflow to the Step Functions Workflows Collection, submit an issue with the following information.

To learn more about submitting a workflow, read the publishing guidelines page.

1. Use the model template located at https://github.com/aws-samples/step-functions-workflows-collection/tree/main/_workflow-mode to set up a README, template and any associated code.

2. All the information below must be provided in the "example-workflow.json" file cloned from the model **

Note the following information for the model:

• Description (intro.text) should be a 300-500 word explanation of how the pattern works.
  This workflow demonstrates how to implement the event sourcing design pattern using AWS Step Functions.

The example implementation demonstrates a mock product inventory workflow. All product inventory events are sent to a Step Function workflow which executes series of task and persists the state of a business entity (Product) as a sequence of state-changing events. Each task contains mock logic that processes a specific product event (ex: productReceived, ProductShipped etc.). It then passes on the updated product state to the next processing task. The updated product state changes along with input event is stored in the Product Inventory Event log.
