    "headline": "How it works",
    "text": [
      "This pattern deploys a Lambda durable function written in Java that orchestrates a multi-step order processing workflow. The function uses the Durable Execution SDK for Java (v1.0.1) to automatically checkpoint progress at each step.",
      "The workflow: (1) validates the order, (2) reserves inventory, (3) processes payment, (4) waits for warehouse processing (no compute charges), (5) confirms shipment. Each step is checkpointed, so if the function is interrupted, it resumes from the last completed step.",
      "This is the first Java-based durable execution pattern. The Java SDK provides an idiomatic experience with DurableHandler<I,O> and DurableContext, supporting steps, waits, callbacks, invoke, map, and parallel operations."
