Serverless Event-Driven Services for Spring Developers
summary
Uses Java and Spring-like annotations on the Kalix.io PaaS to build database-less, Kubernetes-less, ops-less serverless services that persist events, project CQRS views, and run stateless actions as functions. Implements a 13-microservice demo that splits a checkout into nine order-SKU items, uses actions to turn events into many commands, and wires choreographed sagas plus generation and reduction trees to allocate stock. Guarantees at-least-once delivery, forces idempotent consumers, and shows how event sourcing replaces cross-service transactions.
