Aws Lambda Durable Functions

This walks you through AWS Lambda's durable execution SDK for building multi-step workflows that can run up to a year with automatic state persistence. The skill covers the replay model (critical: non-deterministic code like Date.now() must live inside steps or you'll corrupt state), step operations, wait/callback patterns for human-in-the-loop scenarios, and the saga pattern for compensating transactions. It includes specific guardrails like the requirement for qualified ARN invocation and the no-nesting rule for durable operations. Useful if you're building order processing, approval workflows, or AI agent orchestrations where you need reliable progress tracking and automatic retries without managing your own state machine infrastructure.
