Kafka is a high-throughput distributed publish/subscribe message system. It can replace traditional message queues for decoupling Data Processing and caching unprocessed messages. It also has a higher throughput, it supports partitioning, multiple copies, and redundancy, and is widely used in large-scale message data processing applications.
