Apache Kafka: A Guide to Download and Setup on Windows

Apache Kafka is a powerful open-source platform for managing and processing real-time data streams. Setting up Kafka might seem intimidating if you’re working with large-scale data in a Windows environment. However, the process is surprisingly straightforward. Let’s break it down.

Prerequisites

• Java Development Kit (JDK): Kafka is built on Java, so you’ll need the JDK installed. For optimal compatibility, choose JDK version 11 or later. You can download it from Oracle’s website.
• Windows Subsystem for Linux (Optional): While not strictly mandatory, WSL simplifies working with Kafka command-line tools. Learn how to install WSL on Microsoft’s documentation site.

Steps

1. Download Apache Kafka

• • Visit the Apache Kafka downloads page: 
  • Choose the latest stable release under “Binary Downloads.”
  • Select the appropriate Scala version (2.13 is generally recommended).

1. Extract the Archive

• • Extract the downloaded .tgz file to your desired location on your Windows system (for example, C:\kafka).

1. Configure Kafka (Essential)

• Zookeeper Configuration: Kafka relies on Zookeeper for coordination.
  • • Navigate to the config folder inside your Kafka directory.
  • Open zookeeper.properties and modify the dataDir property to point to a directory for storing Zookeeper data (e.g., C:\kafka\zookeeper-data). Create this directory if it doesn’t already exist.
• Kafka Server Configuration:
  • • Open the server.properties file in the config folder.
  • If you plan to access Kafka from other machines, you should adjust the listener’s property to match your network setup.

1. Start the Services

• Start Zookeeper:
  • • Open a terminal or command prompt.
    • Navigate to the bin\windows directory inside your Kafka installation.
  • Run zookeeper-server-start.bat config\zookeeper.properties
• Start Kafka Server:
  • • Open another terminal or command prompt.
    • Navigate to the bin\windows directory.
  • Run kafka-server-start.bat config\server.properties

1. Verification (Optional but Recommended)

• Create a test topic:
  • kafka-topics.bat –create –bootstrap-server localhost:9092 –replication-factor 1 –partitions 1 –topic test-topic
  • Produce messages: kafka-console-producer.bat –broker-list localhost:9092 –topic test-topic
  • Consume messages: kafka-console-consumer.bat –bootstrap-server localhost:9092 –topic test-topic –from-beginning

Additional Notes

• Running as Services: Consider setting up Zookeeper and Kafka as Windows services for production environments.
• Firewalls: Ensure your firewall rules allow necessary network traffic for Kafka.
• Windows Subsystem for Linux: If you are using WSL, starting Zookeeper and Kafka involves using the Linux-like commands within WSL rather than the .bat files.

Congratulations! You’ve successfully downloaded and set up Apache Kafka on your Windows system. With Kafka’s powerful features, you’re on your way to building scalable and performant distributed data pipelines.
