Kafka is a high-throughput distributed publish-subscribe messaging system that can handle all action streaming data in consumer-scale websites. Such actions (web browsing, searches and other user actions) are a key factor in many social functions on the modern web. This data is typically addressed by processing logs and log aggregation due to throughput requirements. For log data and offline analysis systems like Hadoop, but requiring real-time processing constraints, this is a feasible solution. The purpose of Kafka is to unify online and offline message processing through Hadoop's parallel loading mechanism, and to provide real-time consumption through clusters.
