Eventlet: Concurrent Networking Library for Python

Eventlet is a concurrent networking library for Python that allows developers to easily write highly scalable servers. It uses green threads to provide asynchronous I/O without having to deal with callback functions or program complexity.

What is Eventlet?

Eventlet is a concurrent networking library for Python that allows developers to easily write highly scalable network servers. It uses cooperative multitasking and coroutines to provide a high-level synchronous API on top of asynchronous I/O. This makes it easier for developers to write concurrent and parallel code without having to deal with locks, callbacks, threading, or other complexities.

Some key features of Eventlet include:

• Green threads - Lightweight execution units mapped onto native OS threads.
• Asynchronous I/O - Non-blocking sockets and file operations for high scalability.
• Cooperative multitasking - Yielding execution instead of thread blocking when I/O is occurring.
• Synchronous programming style - Avoids complex callback-based code.
• Integration with networking protocols - WSGI support, DNS queries, web servers, etc.

Eventlet is commonly used for building high-performance network servers and applications that need to handle a lot of concurrent users and I/O without creating thousands of threads. For example, real-time analytics systems, web APIs, streaming and caching servers. It scales very well horizontally across multiple processes and machines.
