Tornado

About Tornado

Python web framework and asynchronous networking library. Particularly useful for long-polling, WebSockets, and applications requiring long-lived connections to each user.

Key Features

• 1Non-blocking I/O event loop with WebSocket support
• 2Coroutine-based async programming with `async`/`await`
• 3Built-in HTTP client for making async upstream API requests
• 4Authentication utilities: secure cookies, XSRF protection
• 5Scales to tens of thousands of open connections per process

How Python Data Engineers Use Tornado

Python data engineers use Tornado for long-lived connection scenarios — WebSocket servers that stream real-time pipeline metrics to dashboards, or webhook receivers that accept high volumes of inbound events. Tornado's event loop handles thousands of concurrent connections in a single process, making it efficient for I/O-bound data ingestion services.
