Lagom is Lightbend's reactive micro-service framework, with intuitive and simple abstractions for Command Query Responsibility Segregation (CQRS) and Eventsourcing (ES). By modelling changes in an application as only events, they become the only source of truth. The events are then used for constructing current state of the system (in aggregate root), creating optimized view for querying (read-side) and propagating changes to other systems in asynchronous fashion (message-producer). In this talk, we will survey concepts in CQRS and ES, explain why Lagom might be a good candidate for your next micro-service, and highlight how data consistency within and across micro-services is addressed.
