Kafka Development

This course provides a technical introduction to Kafka development. The course describes the design goals underpinning Kafka, and explains key Kafka concepts such as partitions, replication, and consumer groups. The course then leads you on a detailed tour of the Kafka APIs in Java: you’ll learn how to publish and consume data to Kafka topics; how to manage the Kafka environment via the AdminClient API; and how to implement a stream-processing topology via the Streams API.

What you will learn:

• Understanding Kafka design goals and architecture
• Setting up a development environment for Kafka
• Using the Kafka Producer and Consumer APIs
• Using the Kafka AdminClient API
• Using the Streams API
• Using Kafka in Spring Boot

Prerequisites:

Solid programming experience in Java or a similar language
