Projections: Creating Read-Optimised Data

Data continuously flows through organisations, and on its way, it’s transformed many times to serve different purposes. Functional design emphasises data transformation—projections— rather than repeatedly mutating state in a single database. One particularly useful form of projection is the creation of read-optimised data structures tailored to well-defined use cases.

Kafka – Managing Breaking Changes in a Multi-Team Environment

However, merely understanding these concepts falls short when operating within an environment characterized by numerous teams and bounded contexts. It is necessary to identify patterns and principles for navigating model changes successfully.

"From 2015 to 2017 I had the pleasure of working together with Christina again. She was the lead architect then and responsible for making strategic architectural decisions for the products we developed. In my opinion she couldn't have done a better job. In that role she arranged meetings within the development team to discuss the direction we were going and even though she usually was the most competent one in the room she always appreciated an open discussion, knowing that a decision based on our collective knowledge was preferable. She is a natural leader and I can only hope I'll have the privilege of working with her again."
