If you are a Java developer exploring Apache Kafka, one of the first things you will build is a Kafka Producer. The producer is responsible for publishing data (messages) to Kafka topics. In this Kafka Producer Java tutorial, we’ll walk you through the step-by-step process of building a producer, sending JSON and custom objects, handling retries, and implementing best practices.
By the end of this guide, you’ll be able to:
- Write a Kafka Producer Java example to send string, JSON, and custom messages.
- Implement a Kafka custom serializer in Java.
- Configure retry logic and error handling in a Kafka producer.
- Follow Kafka producer best practices for reliability and performance.
