Eventsourcing and cqrs

Beschreibung

Michael Pisula
In distributed, message-driven systems the established CRUD data access can hurt your performance and make consistency hard to achieve. CommandQueryResponsibiltySegregation (CQRS) is a different approach where data flows to modify and read data are separated. CQRS has its roots in Domain Driven Design, and ties in nicely with another DDD concept, Event Sourcing. Akka is an awesome actor-based, message-driven toolkit that offers support for Event Sourcing and CQRS. In this talk I will present the ideas behind the concepts, show benefits and counterindications, before presenting how CQRS and ES can be used in Akka.
