Total Recall - The application that never forgets

By Holger Woltersdorf

Elevator Pitch

You want to keep record of all data that means value to your business? And you want to speed up your application? Apply CQRS and Event Sourcing and discover the opportunity to do both, even on an existing system.


Building an application upon CQRS and Event Sourcing offers three pretty nice benefits.

  1. Well structured code and business logic, separated by read and write concerns.
  2. The source of truth - A reliable and recoverable view into the past of your application state.
  3. The opportunity to answer future questions that you don’t know about today.

This talk explains the good fit of two combined application architecture approaches applied to a well known real world example. It shows how to tackle some pitfalls, gives practical advices on infrastructure and exemplifies the aforementioned benefits.


This talk was given at PHPkonf Istanbul in May 2017.
