Chapter 3. Adding client dependencies to your Maven project

If you are developing Java-based Kafka clients, you can add the Red Hat dependencies for Kafka clients, including Kafka Streams, to the pom.xml file of your Maven project. Only client libraries built by Red Hat are supported for Streams for Apache Kafka.

You can add the following artifacts as dependencies:

kafka-clients

Contains the Kafka Producer, Consumer, and AdminClient APIs.

  • The Producer API enables applications to send data to a Kafka broker.
  • The Consumer API enables applications to consume data from a Kafka broker.
  • The AdminClient API provides functionality for managing Kafka clusters, including topics, brokers, and other components.
kafka-streams

Contains the KafkaStreams API.

Kafka Streams enables applications to receive data from one or more input streams. You can use this API to run a sequence of real-time operations on streams of data, like mapping, filtering, and joining. You can use Kafka Streams to write results into one or more output streams. It is part of the kafka-streams JAR package that is available in the Red Hat Maven repository.
