Kafka EI Connector

The Kafka connector allows you to access the Kafka Producer API through WSO2 EI and acts as a message producer that facilitates message publishing. The Kafka connector sends messages to the Kafka brokers.

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.
