Aws Lambda Durable Functions

If you're building workflows that need to survive restarts, handle retries gracefully, or coordinate multi-step processes that run for days or months, this is worth learning. It's AWS's answer to durable execution patterns, letting Lambda functions checkpoint their progress and resume after interruptions. The replay model takes some getting used to (anything non-deterministic must go in a step, no nesting durable operations), but once you internalize those rules, you can build surprisingly resilient systems. Supports TypeScript, JavaScript, and Python. The skill covers the fundamentals plus practical patterns like saga compensation, human-in-the-loop callbacks, and parallel execution. Good for AI agents, approval workflows, or any serverless process that shouldn't start over from scratch when something fails.
