-----

Build reliable, long-running AWS Lambda workflows with checkpointed steps, waits, callbacks, and parallel execution.

## ✨ Key Features

- **Automatic checkpointing** - Resume execution after Lambda pauses or restarts
- **Durable steps** - Run work with retry strategies and deterministic replay
- **Waits and callbacks** - Pause for time or external signals without blocking Lambda
- **Parallel and map operations** - Fan out work with configurable completion criteria
- **Child contexts** - Structure complex workflows into isolated subflows
- **Replay-safe logging** - Use `context.logger` for structured, de-duplicated logs
- **Local and cloud testing** - Validate workflows with the testing SDK

## 📦 Packages

| Package | Description | Version |
| --- | --- | --- |
| `aws-durable-execution-sdk-python` | Execution SDK for Lambda durable functions | [![PyPI - Version](https://img.shields.io/pypi/v/aws-durable-execution-sdk-python.svg)](https://pypi.org/project/aws-durable-execution-sdk-python) |
| `aws-durable-execution-sdk-python-testing` | Local/cloud test runner and pytest helpers | [![PyPI - Version](https://img.shields.io/pypi/v/aws-durable-execution-sdk-python-testing.svg)](https://pypi.org/project/aws-durable-execution-sdk-python-testing) |

## 🚀 Quick Start

Install the execution SDK:

```console
pip install aws-durable-execution-sdk-python
```

Create a durable Lambda handler:

```python
from aws_durable_execution_sdk_python import (
    DurableContext,
    StepContext,
    durable_execution,
    durable_step,
)
from aws_durable_execution_sdk_python.config import Duration

@durable_step
def validate_order(step_ctx: StepContext, order_id: str) -> dict:
    step_ctx.logger.info("Validating order", extra={"order_id": order_id})
    return {"order_id": order_id, "valid": True}

@durable_execution
def handler(event: dict, context: DurableContext) -> dict:
    order_id = event["order_id"]
    context.logger.info("Starting workflow", extra={"order_id": order_id})

    validation = context.step(validate_order(order_id), name="validate_order")
    if not validation["valid"]:
        return {"status": "rejected", "order_id": order_id}

    # simulate approval (real world: use wait_for_callback)
    context.wait(duration=Duration.from_seconds(5), name="await_confirmation")

    return {"status": "approved", "order_id": order_id}
```
