Getting Stomp working using Spring was very easy. It didn’t seem that easy to me because I tested my implementation with an integration test which seemed to fail at least as much as it succeeded. In this post I will take you through my journey of getting a stable integration test on Spring Websockets.
In short, Kafka is a horizontally scalable streaming platform. In other words, Kafka is a message broker which can be run on multiple servers as a cluster. Different data streams are called topics. Producers can place messages on a topic whereas consumers can subscribe to topics. Topics can be configured for single- and multiple delivery of messages. Consumers can be grouped in so called consumer-groups, which makes it possible for multiple consumers to act as one when it comes to single-delivery.
