Talks - Arthur Pastel: Demystifying AsyncIO: Building Your Own Event Loop in Python
AsyncIO has emerged as a vital tool in Python's ecosystem, particularly in web development, IO-bound tasks, and network programming. However, its internal mechanics often remain obscure, even to seasoned Python developers. This talk aims to demystify AsyncIO by guiding you through creating your own event loop in Python, culminating in running a FastAPI application with it.
In this talk, we’ll build an event loop from scratch in Python, capable of running an HTTP server through a FastAPI application.
Plan:
Introduction to AsyncIO
Core Concepts: Deep dive into Event loop, Futures, Tasks, and coroutines
Hands-On Building: Constructing an event loop from scratch
Scheduling callbacks
Executing tasks and coroutines
Handling network calls
Practical Application: Running a FastAPI HTTP server with our loop
Performance Insights: Comparing our event loop with the fastest ones
By the end of this talk, you'll be able to understand the internal workings of AsyncIO and create a basic event loop capable of running a FastAPI application.
