Kafka, an open-source real-time streaming messaging system, operates on a publish-subscribe model where producers send data to feeds that consumers subscribe to, enabling efficient information exchange with high performance and minimized failure risk. It distributes and replicates data across multiple servers, allowing for low-latency, fault-tolerant data movement between system components. Kafka's architecture supports features like high-throughput and near-limitless scalability by utilizing commit logs and enabling concurrent consumer processing. Key components include brokers, which manage data distribution, and topics, which organize data streams for producers and consumers. Kafka supports various use cases, such as IoT networks, real-time analytics, and large-scale message processing, by employing consumer groups, partitions, and replicas to ensure data durability and availability. Additionally, Kafka Connect facilitates data import and export from external sources, while Kafka Streams offers real-time data processing capabilities. ZooKeeper plays a crucial role in maintaining metadata and coordinating broker activities, ensuring the overall system's reliability and efficiency. Since its inception by LinkedIn in 2011, Kafka has become a prominent platform for data distribution and streaming in various applications.
