Create a Step Functions workflow to invoke Lambda durable functions synchronously and asynchronously with checkpointing.
This pattern demonstrates how to integrate AWS Lambda durable functions into an AWS Step Functions workflow.
It covers both synchronous invocation (using default Request Response pattern) and asynchronous invocation (using the Step Function Wait for Callback with Task Token integration pattern) of durable Lambda functions.
The pattern addresses the challenge of running long-running Lambda functions (beyond 15 minutes) within a Step Functions orchestration, using asynchronous invocation and durable checkpointing.
Lambda durable functions use a checkpoint/replay mechanism that allows Lambda executions to run for up to one year, automatically recovering from interruptions.
