一覽

Tornado is a Python web framework optimized for asynchronous I/O, long-polling, and real-time WebSocket connections. Used by backend engineers and infrastructure teams. Salary: $80-130k junior, $130-190k mid, $190-280k senior. Learn in 3-4 weeks. Adjacent to async Python, FastAPI, and real-time systems.

什麼是 Tornado Async

Tornado is a Python web framework built from the ground up for asynchronous I/O, enabling thousands of concurrent connections with minimal hardware. It's optimized for long-polling, WebSockets, and real-time applications where traditional sync frameworks (Flask, Django) would require one thread per connection. Tornado uses Python's asyncio event loop to handle I/O-bound work asynchronously. A single Tornado instance can manage thousands of concurrent WebSocket connections, making it ideal for chat, live notifications, multiplayer games, and dashboards.

❓ 常見問題

How does Tornado differ from Flask or Django?
Flask and Django are sync-first; Tornado is async-first. Tornado is optimized for thousands of concurrent connections; Flask is better for traditional request-response. Tornado excels at WebSockets; Flask requires extensions.
Can I use Tornado for traditional web apps?
Yes, but it's overkill. Tornado's advantage is async I/O and real-time; if you don't need those, Flask is simpler and more popular.
How many concurrent connections can Tornado handle?
A single Tornado instance can handle thousands (5k-50k depending on hardware). Multiple instances behind a load balancer handle millions.
Is Tornado still relevant?
Yes, though FastAPI has gained popularity for async Python. Tornado is simpler, lighter, and still the default for WebSocket-heavy applications.
Can I use Tornado with async libraries?
Yes. Tornado integrates with asyncio, aiohttp, sqlalchemy async. You can use async libraries freely in Tornado handlers.
