Explanation

To perform real-time computation on Storm, we create "topologies." A topology is a graph of a computation, containing a network of nodes called "Spouts" and "Bolts." In a Storm topology, a Spout is the source of data streams and a Bolt holds the business logic for analyzing and processing those streams. The org.apache.storm.kafka.KafkaSpout component reads data from Kafka. https://docs.microsoft.com/en-us/azure/hdinsight/hdinsight-apache-storm-with-kafka https://hortonworks.com/blog/storm-kafka-together-real-time-data-refinery/
