Topics

A Kafka topic defines a channel through which data is streamed.Producers publish messages to topics,and consumers read messages from the topic they subscribe to.

Topics organize and structure messages,with particular types of messages published to particular topics.Topics are identified by unique names within a Kafka cluster, and there is no limit on the number of topics that can be created.
