How to setup KAFKA ? Bigginner guide for KAFKA

Kafka is a distributed event streaming platform that is widely used for building real-time data pipelines and streaming applications. Here is a step-by-step guide to setting up Apache Kafka on a single machine for development and testing purposes:

1. Install Java: Kafka requires Java to be installed on your system. You can download and install the latest version of Java from the official website.

2. Download Apache Kafka: Download the latest stable release of Apache Kafka from the official website. Extract the archive to a location of your choice.

3. Start ZooKeeper: Apache Kafka uses Apache ZooKeeper for cluster management. To start a ZooKeeper instance, navigate to the location where you extracted the Kafka archive, and then run the following command:

bash
bin/zookeeper-server-start.sh config/zookeeper.properties

4. Start Kafka broker: To start a Kafka broker, run the following command:

bash
bin/kafka-server-start.sh config/server.properties

5. Create a topic: To create a topic in Kafka, run the following command:

css
bin/kafka-topics.sh --create --bootstrap-server localhost:9092 --replication-factor 1 --partitions 1 --topic my-topic

6. Publish messages to a topic: To publish messages to a topic, run the following command:

python
bin/kafka-console-producer.sh --bootstrap-server localhost:9092 --topic my-topic

7. Consume messages from a topic: To consume messages from a topic, run the following command:

python
bin/kafka-console-consumer.sh --bootstrap-server localhost:9092 --topic my-topic --from-beginning

This is a basic setup for Apache Kafka, and you can use it for testing and development purposes. For a production-ready setup, you'll need to consider factors such as performance, scalability, and security, and adjust your configuration accordingly.
