armonizing Asynchronous Systems: NATS, CloudEvents and AsyncAPI.

on YouTube ↗22m

" summary

A small observability platform is built with Java Spring Boot services: a demo app, a metrics agent, a data-collector and a reporter, all exchanging NATS JetStream messages carrying CloudEvents gem payloads; AsyncAPI files document channels and reference JSON Schemas used to generate classes. AsyncAPI 3.0 uses explicit action send/receive so publishers and consumers map clearly. The live demo shows memory varying 2–4 GB and CPU 20–80% on the HTML dashboard, proving the pipeline and codegen approach work end-to-end.
