Kafka Connector Overview

Kafka is a distributed publish-subscribe messaging system that maintains feeds of messages in topics. Producers write data to topics and consumers read from topics. For more information on Apache Kafka, see Apache Kafka documentation.

Kafka mainly operates based on a topic model. A topic is a category or feed name to which records get published. Topics in Kafka are always multi-subscriber.

To see the Kafka Connector, navigate to the connector store and search for "kafka".
