This repository contains common Kafka code supporting Cerner's cloud-based solutions.

For Maven, add the following,

<!-- For client utilities -->
<dependency>
    <groupId>com.cerner.common.kafka</groupId>
    <artifactId>common-kafka</artifactId>
    <version>3.0</version>
</dependency>
<!-- For connect utilities -->
<dependency>
    <groupId>com.cerner.common.kafka</groupId>
    <artifactId>common-kafka-connect</artifactId>
    <version>3.0</version>
</dependency>
<!-- For test utilities -->
<dependency>
    <groupId>com.cerner.common.kafka</groupId>
    <artifactId>common-kafka-test</artifactId>
    <version>3.0</version>
</dependency>

Project Inventory

The following modules are available for use,

• common-kafka: Lightweight wrapper for producers and consumers in the kafka-clients library.
• common-kafka-connect: Contains Kafka Connect component implementations.
• common-kafka-test: Provides infrastructure for integration or "heavy" unit tests that need a running Kafka broker and ZooKeeper service.

Please refer to the project-specific README documentation for content details.

Version Requirements

The 3.0 release of common-kafka uses the following dependency versions.

• Kafka: 3.2.0
• Metrics: 2.2.0
• Scala: 2.13.5

Note that the Scala dependency is only applicable for common-kafka-test.

Upgrading from common-kafka 2.x to 3.0

• The common-kafka-admin module has been removed, KafkaAdminClient can be replaced by Kafka's admin client
• KafkaBrokerTestHarness has been updated to require TestInfo in the setup method, which requires junit5. By extending AbstractKafkaTests instead of using KafkaBrokerTestHarness directly you can avoid needing to add a junit5 dependency.
