Pattern: lambda-durable-function-chaining-cdk
This pattern demonstrates an e-commerce order processing workflow using AWS Lambda Durable Functions with function chaining, deployed via AWS CDK.
How it works
Processes orders through a 4-step workflow: validation → payment → inventory → fulfillment. The orchestrator function uses durable execution to checkpoint each step, so if something fails, it picks up where it left off instead of starting over.
The payment function fetches pricing from DynamoDB, inventory gets decremented when allocated, and if fulfillment fails, there's compensation logic to put the inventory back.
