What is Apache Kafka? The Full 2026 Guide (Introduction)
Finally, we introduce the star of the show: Apache Kafka. In this lecture, we move beyond the theory and dive into the world’s most powerful distributed streaming platform. We explore what Kafka is, why it was named after a famous author, and how it evolved from a LinkedIn internal project into a powerhouse used by 80% of the Fortune 100.
We also discuss the massive shift in Kafka 4.0, specifically the removal of Zookeeper in favor of KRaft, and what this means for you as a developer in 2026.
What you will learn in this video:
The 3-Part Definition: Why Kafka is Open Source, Distributed, and a "Streaming Platform."
