Axon Framework : A CQRS Approach to Microservices
summary
Axon offers a practical CQRS + event‑sourcing stack that plugs into Spring Boot and builds a working three‑service demo (UI → Axon Hub → account service, events stored in AxonDB, projections in MySQL) with command/query buses, tracking processors and test fixtures. Claims: over 1M+ downloads and production use at finance, logistics and hospitals. Demo runs end‑to‑end, supports simple scale‑out, and surfaces real tradeoffs: eventual consistency, event versioning, and when CQRS/event sourcing are inappropriate.
