Apache Kafka - Real-time Stream Processing (Master Class) - Kafka Cluster Architecture

The video tutorial explains the scalability and clustering of Apache Kafka, focusing on how Kafka brokers form a cluster and manage workloads. It discusses the role of Zookeeper in maintaining active brokers and the concept of a masterless cluster. The tutorial also covers the responsibilities of the Kafka controller, which is elected among brokers to handle administrative tasks. The process of controller election and the role of ephemeral nodes in Zookeeper are detailed, providing a comprehensive understanding of Kafka's distributed system architecture.
