In event-driven systems, integration testing plays a significantly different role than in traditional request-response architectures. When a service communicates over HTTP, tests usually verify synchronous responses. Kafka-based systems, however, introduce asynchronous message flows, eventual consistency, and distributed state transitions. This fundamentally changes how we must design and implement integration tests. A Kafka integration test must […]
Apache Kafka: The Backbone of Modern Distributed Systems
Apache Kafka has evolved from a high‑throughput messaging system into one of the most influential pillars of modern distributed architectures. It powers everything from real‑time analytics pipelines to event‑driven microservices, fraud detection systems, IoT platforms, and mission‑critical financial workflows. In a world where systems must be scalable, resilient, and capable of processing massive streams of […]
