Eventing with Apache Kafka
When building our microservice platform we wondered how services should consume data without opening the gates of hell by doing endless chains of API calls. We realized one fact: Having data is better than needing data. Therefore we decided to allow services to keep data redundant. Letting 40 teams work as autonomous as possible we introduced “eventing” and Apache Kafka to reduce dependencies when answering requests. This talk shows the principles and basics about asynchronous communication with Apache Kafka along with code samples. We’ll show you how simple producers and consumers can be written, how domain events are passed around between services and the most common pitfalls to be avoided for developers.
