Conquer Apache Kafka 2025 – Dive into Data Streaming Dominance!

Zookeeper plays a crucial role in the functioning of Apache Kafka by managing and coordinating the Kafka brokers. It is responsible for maintaining the metadata about brokers, topics, partitions, and consumer groups within a Kafka cluster. This coordination is essential for ensuring that Kafka operates reliably, especially in a distributed system where multiple brokers are involved. Zookeeper facilitates leader election for partitions, tracks the status of brokers, and handles various configurations. Because of these functions, it helps ensure high availability and fault tolerance of Kafka messaging.

The other options do not capture Zookeeper's primary purpose in Kafka. For instance, Zookeeper does not store user data; instead, it is focused on configuration and state management. While it does coordinate brokers, it does not act as a message broker itself, which is a primary function of Kafka. Finally, Zookeeper does not provide API endpoints for Kafka; rather, Kafka clients interact directly with Kafka brokers to publish and consume messages.
