AsyncIO in Production - War Stories

Explore the challenges and triumphs of implementing AsyncIO in production environments through this insightful EuroPython 2019 conference talk. Delve into Michal Wysokinski's two-year journey with AsyncIO, uncovering both its potential as a performance-enhancing tool and the complexities it introduces as a novel approach. Learn about successful AsyncIO implementations, instances where traditional fork-join architecture proved more suitable, and gain valuable insights into project suitability for AsyncIO adoption. Discover the intricacies of parallel execution, event loops, and AsyncIO history while examining real-world examples of synchronous and asynchronous code. Analyze memory and CPU usage patterns, microservice architectures, and the pros and cons of AsyncIO implementation. Equip yourself with practical knowledge to determine which projects can benefit most from AsyncIO and which should consider alternative solutions.
