Since it was open sourced, Apache Kafka has been adopted very widely from web companies like Uber, Netflix, LinkedIn to more traditional enterprises like Cerner, Goldman Sachs and Cisco. At these companies, Kafka is used in a variety of ways - as a pipeline for collecting high-volume log data for load into Hadoop, a means for collecting operational metrics to feed monitoring and alerting applications, for low latency messaging use cases and to power near real-time stream processing.
