List of links from Designing Event-Driven Systems by Ben Stopford

Designing Event-Driven Systems book by Ben Stopford contains a lot of useful links to papers, books, documentation and definitions related to event driven design and Kafka. I just extracted them as reference for the future and added some groups to show them better.
