akka-ddd - Akka CQRS/ES framework

•    Scala

---

Akka-DDD is a framework for building distributed services following DDD/CQRS/ES architecture on top of the Akka platform. Thanks to the pluggable architecture of the Akka-Persistence, Akka-DDD is not tied to any particular event journal provider. The services are built as actor systems. Different services can be distributed in the same cluster (Akka cluster) or can be deployed to independent clusters.

eventhorizon - CQRS/ES toolkit for Go

•    Go

---

Event Horizon is a CQRS/ES toolkit for Go. CQRS stands for Command Query Responsibility Segregation and is a technique where object access (the Query part) and modification (the Command part) are separated from each other. This helps in designing complex data models where the actions can be totally independent from the data output.
