Kafka Course Home

Introduction

Learn Apache Kafka in 12 clear modules — from your first topic to production operations. Start with Module 1 and follow the sidebar in order, or pick a role-based path on the course page.

Understanding the topic

Course map:

• 1–2: What Kafka is, core concepts (topics, partitions, producers, consumers).
• 3–4: Producers and consumers in depth.
• 5: Connect, Schema Registry, Kafka Streams.
• 6–7: Operations, security, troubleshooting.
• 8–12: Advanced patterns, Spring Kafka, projects, interviews.

Informative example

Quick start — create a topic and send a message:

kafka-topics --bootstrap-server localhost:9092 --create --topic orders --partitions 6 --replication-factor 3
kafka-console-producer --bootstrap-server localhost:9092 --topic orders
kafka-console-consumer --bootstrap-server localhost:9092 --topic orders --from-beginning
kafka-consumer-groups --bootstrap-server localhost:9092 --describe --group orders-service

Best practices

• Follow modules 1 → 2 → 3 → 4 on your first pass.
• Run the CLI examples locally — Kafka makes sense when you see partitions yourself.

Common mistakes

• Skipping Core Concepts and jumping straight to Streams or Staff modules.

Summary

Kafka is a distributed log for real-time data pipelines. This course teaches it step by step.
