SAGA Pattern using AWS Lambda durable functions
This pattern demonstrates AWS Lambda durable functions with saga orchestrator for distributed transaction coordination using Python 3.13, DynamoDB, and CDK. Key features include:
The pattern showcases how to implement a travel booking system where Lambda functions coordinate multiple service reservations and automatically compensate (rollback) completed steps when any downstream service fails.
