Azure Durable Functions
An extension of Azure Functions for writing stateful functions in a serverless compute environment.
Overview
Durable Functions is an extension of Azure Functions that lets you write stateful functions in a serverless compute environment. The extension lets you define stateful workflows by writing orchestrator functions and stateful entities by writing entity functions using the Azure Functions programming model. Behind the scenes, the extension manages state, checkpoints, and restarts for you, allowing you to focus on your business logic.
✨ Key Features
- Stateful workflows as code (C#, JavaScript, Python, etc.)
- Built on top of Azure Functions
- Automatic state management and checkpointing
- Support for various application patterns (chaining, fan-out/fan-in, async HTTP APIs)
- Durable timers for long-running delays
🎯 Key Differentiators
- Code-first, developer-centric approach
- Deep integration with the Azure Functions platform
- Leverages existing programming models
Unique Value: Build complex, stateful, and long-running serverless orchestrations using familiar programming languages and the Azure Functions model.
