Rails Event Store is a Ruby library to persist, retrieve, publish and organize application architecture around domain events in an event-driven fashion. It’s not a database itself, building on top of and existing (typically an SQL) data store in the application. It makes a great foundation for CQRS, Event Sourcing and loosely coupled components in applications driven by domain events.

We’ve just reached 1.0 milestone!
