Order processing workflow using Lambda durable functions with automatic checkpointing, long-running waits, and state persistence
This pattern demonstrates an order processing workflow using Lambda durable functions.
The workflow includes validation, payment processing, fraud checks, credit checks (for high-value orders), inventory management, and shipping coordination.
Durable execution enables long-running waits (5 minutes for warehouse processing, 3 minutes for carrier pickup) without consuming compute resources.
Each step is automatically checkpointed, allowing the workflow to survive interruptions and resume from the last successful step.
The pattern uses a dual-function architecture: async durable function for order processing and sync non-durable function for real-time status queries.
Order state is persisted in Amazon DynamoDB with real-time status updates throughout the 17-step workflow.
