SymfonyCon Berlin 2016 - Samuel Roze - A CQRS and Event Sourcing approach in a Symfony application
The Command Query Responsibility Segregation pattern, instead of the traditional CRUD, introduce different models for reading and updating the application states. Event Sourcing is the idea that every state of your application can be represented by a sequence of events. Using these two principles as the heart of a system or an application is quite common but can be challenging if we don’t use the right tools or architecture. With a concrete application as example, we’ll go through the architecture, libraries and bundles we can use in a Symfony application in order to apply these patterns.
