In the rapidly-evolving world of Python web development, the emergence of frameworks like FastAPI has changed how software engineers build highly-performant, asynchronous applications in Python. This lightning talk will explore how the FastAPI framework makes use of the power of an Asynchronous Server Gateway Interface (ASGI) web server to enable concurrent request handling, in contrast with the traditional Web Server Gateway Interface (WSGI) approach.
Through a live demonstration, the differences between WSGI and ASGI applications will be illustrated. Synchronous applications can be blocked by long-running tasks such as I/O operations, whereas asynchronous web servers handle requests concurrently even while the thread is occupied with different tasks.
By showcasing how FastAPI's design allows for concurrent processing of multiple requests without blocking, this talk will highlight the significant performance benefits and scalability advantages provided by ASGI-powered frameworks.
