      "This pattern deploys an AWS Lambda durable function and a standard AWS Lambda function. The durable function uses the durable execution SDK to orchestrate a workflow that prepares input data in a checkpointed step and then invokes the standard Lambda function using context.invoke().",
      "The context.invoke() call creates a checkpoint so that if the durable function is interrupted after the invoked function completes, it resumes with the stored result without re-invoking the processor function.",
      "This pattern deploys two Lambda functions with the required IAM permissions for durable execution and cross-function invocation."
