Supersonic, Subatomic Java

on YouTube ↗01h 01m

" summary

Shows a runnable Quarkus pipeline using microprofile reactive messaging: an HTTP producer pushes JSON to Kafka, a transformer service reads the topic, computes quantity price -> extendedPrice and flags special customers, writes a new topic, and streams results to the browser via WebSocket/Server-Sent Events. Demonstrates live edit/reload, emitter/backpressure behavior, Vert.x foundation, operator-driven Kafka deployment, and size/startup claims (fat jar ~136 MB, JVM Quarkus ~73 MB, native 12 MB*, example native CRUD startup ~0.03s).
