asyncio Reviews

Tornado is a Python web framework that doubles as an asynchronous networking library, originally developed at FriendFeed. With its non-blocking network I/O, it can handle tens of thousands of concurrent connections, making it ideal for applications that rely on persistent user connections like long polling and WebSockets. Distinct from most Python web frameworks, Tornado does not adhere to the WSGI standard and typically functions on a single thread per process. While the tornado.wsgi module provides a degree of WSGI compatibility, it is not the primary focus of the framework’s development, and it is recommended that developers utilize Tornado’s dedicated interfaces, such as tornado.web, when creating applications. Additionally, it is crucial to understand that Tornado's code is generally not thread-safe. Since the release of version 5.0, Tornado has been integrated with Python's standard library asyncio module, allowing it to share the same default event loop. This integration facilitates the use of libraries built for asyncio alongside Tornado, significantly enhancing its versatility and overall functionality. Consequently, developers can construct highly efficient applications that harness both the strengths of Tornado and the capabilities of asyncio, leading to more robust and responsive user experiences. The adaptability of Tornado has made it a popular choice among developers who require high performance in their web applications.
