Apache Kafka includes five core APIs:

The Producer API allows applications to publish streams of events to one or more topics
The Consumer API allows applications to consume published events from one or more topics
The Streams API allows transforming streams from input topics and publish the results to output topics
The Connect API allows support for various input and output sources to capture and dump stream of events
The AdminClient API allows topics and server management along with other Kafka management...
