Reactive Programming in Java

on YouTube ↗49m

" summary

Shows reactive concepts by wiring a live stock feed example that emits values, handles errors, and lets clients unsubscribe when a target price is reached. Uses RX Java to create an observable that pushes data, demonstrates filtering, onNext/onError/onComplete channels, and a demo of unsubscribing to stop work. Explains scaling tradeoffs with back pressure, hot vs cold streams, and elastic, message driven design, citing surprising load patterns like 50 million users spiking in a few days.
