Serverless Java on Knative with Quarkus
summary
Three Quarkus services (order, payment, stock) run on OpenShift using Kafka and Knative Serving/Eventing; code uses Quarkus Funqy and SmallRye Reactive Messaging and builds native-friendly images. A KafkaSource CRD forwards two topics (order-events, reserve-events) into the Knative Broker, Triggers route to subscribers, and the demo implements a simple SAGA across three services with one generated order every 10s. Everything deploys via S2I, services scale-to-zero and resume, events flow, and confirmations and rollbacks appear in the logs.
