J-Fall 2022: Berwout de Vries Robles – HTTP/3 and Reactive Streaming

At J-Fall 2019 I gave a musical demonstration to introduce people to HTTP/2 and Reactive Streaming. To do that I developed an application that turns the crowd into my personal orchestra. Now it is 3 years later and HTTP/3 is nearing mainstream adoption! In this talk I will go into the updates in HTTP/3 and why they are so relevant for Reactive Streaming over HTTP. According to the publications about HTTP/3 and QUIC the improvement should be most noticeable on a mobile connection. So in this talk we are going to attempt a live experiment with the audience to see if we can HEAR the difference between HTTP/2 and HTTP/3 connection reflected in the music. I do not personally own hundreds of cellphones to do a live audio test with so this may fail horribly in practice. However, in the worst case you should at least walk away having had some fun at my expense and with some extra knowledge about the HTTP protocol under your belt.
