Apache Kafka in 15 minutes

Apache Kafka, developed by LinkedIn in 2011, is an open-source messaging system known for its scalability and reliability. Kafka is primarily used for event streaming and message queuing, making it ideal for systems requiring high throughput and fault tolerance. It includes key components like producers, brokers, and consumers, and ensures data consistency with features like partitions, replicas, and the at-least-once delivery guarantee. Kafka also optimizes performance with techniques like zero-copying which enhance message throughput significantly.
