Exploring Stateful Microservices built with Open Liberty
summary
Demonstrates how to keep HTTP session data across containers by running Open Liberty in Kubernetes and using JCache + Hazelcast session persistence; builds a simple shopping‑cart microservice, deploys it to a local K8s cluster, and shows the REST endpoints working (POST to add item, GET to retrieve cart). Claims saga/long‑running action patterns and MicroProfile LRA as coordination options, provides GitHub guides and runnable finished code that successfully starts and responds.
