download PDF

The kafka-clients JAR file contains the Kafka Producer and Consumer APIs together with the Kafka AdminClient API.

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

10.1. Adding Kafka clients as a dependency to your Maven project

This procedure shows you how to add the AMQ Streams Java clients as a dependency to your Maven project.

Prerequisites

  • A Maven project with an existing pom.xml.

Procedure

  1. Add the Red Hat Maven repository to the <repositories> section of your pom.xml file.

    <?xml version="1.0" encoding="UTF-8"?>
    <project xmlns="http://maven.apache.org/POM/4.0.0"
             xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
             xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    
        <!-- ... -->
    
        <repositories>
            <repository>
                <id>redhat-maven</id>
                <url>https://maven.repository.redhat.com/ga/</url>
            </repository>
        </repositories>
    
        <!-- ... -->
    
    </project>
  2. Add the clients to the <dependencies> section of your pom.xml file.

    <?xml version="1.0" encoding="UTF-8"?>
    <project xmlns="http://maven.apache.org/POM/4.0.0"
             xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
             xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    
        <!-- ... -->
    
        <dependencies>
            <dependency>
                <groupId>org.apache.kafka</groupId>
                <artifactId>kafka-clients</artifactId>
                <version>2.5.0.redhat-00003</version>
            </dependency>
