Apache Kafka

Apache Kafka is the undisputed backbone of real-time data streaming, processing trillions of messages daily for powerhouses like Uber, Netflix, and Goldman Sachs. It handles over 1 million messages per second in its largest deployments, achieving a latency under 10 milliseconds. Kafka outperforms #6 RabbitMQ in both throughput and scalability, with a distributed architecture ensuring fault tolerance across clusters. This event streaming platform serves as the nervous system for modern data pipelines, where every millisecond counts, from streaming analytics to log aggregation.
