Event Sourcing & CQRS

Event Sourcing

Referring to the Scale-Cube, for further scaling on Z-axis, Event Sourcing/CQRS brings Eventual Consistency which means a shift from ACID to BASE.

 

We apply this dimension, benefiting from klunge.io which is our production-grade Open Source ES/CQRS engine.

 

Enabling Eventual Consistency of your architecture creates a wider opportunity to scale without heavily investing in infrastructure.

CQRS

CRUD resources no longer exist once you are in your transition to Event-based Microservices-driven architectures. The existing habits are changing, but teams may tend to continue with the existing approaches. The transition must be able to address the existing requirements by complying with:

  • Command Models
  • View/Query Model
  • Aggregates
  • Actors
