A reference implementation of an event-sourced system using PostgreSQL as the event store, built with Spring Boot in Java. It demonstrates CQRS, snapshotting, transactional outbox patterns, and Postgres Listen/Notify, and can be forked as a project template or run with end-to-end tests.

Use cases

• implement event sourcing with postgresql
• learn cqrs and event-driven architecture
• use postgres as an event store instead of specialized databases
• template for a spring boot event-sourced project
• implement transactional outbox pattern
• understand optimistic concurrency control for event streams
• build an audit trail with event streams

When to choose

• you want to learn or bootstrap event sourcing and CQRS on PostgreSQL with Spring Boot
• you need a working reference for transactional outbox and projection patterns
• you prefer PostgreSQL over specialized event-store databases

When to avoid

• you need a production-grade event store framework with out-of-the-box features
• your stack is not Java/Spring Boot
• you want a simple state-oriented persistence without event history
