STEP 1: DOWNLOAD KAFKA

Download and Setup Kafka on Windows and Linux

Kafka is a distributed streaming platform that allows you to publish and subscribe to streams of records. In this guide, we will provide links to download and set up Kafka on both Windows and Linux operating systems.

Download Kafka

Windows

You can download the latest version of Kafka for Windows from the Apache Kafka website.

Linux

To download Kafka on Linux, open a terminal and run the following command:

wget https://apache.mirror.digitalpacific.com.au/kafka/3.1.0/kafka_2.13-3.1.0.tgz

This command will download the latest version of Kafka available at the time of writing this guide.

Set Up Kafka

Once you have downloaded the Kafka binaries, follow the steps below to set up Kafka on your system.

Windows

Extract the Kafka archive you downloaded to a directory of your choice.
Navigate to the Kafka directory and open the config folder.
Edit the zookeeper.properties file and replace the dataDir property with a directory path where you want to store ZooKeeper data.
Start ZooKeeper by running the following command from the Kafka directory: bin\windows\zookeeper-server-start.bat config\zookeeper.properties
Open a new command prompt window and navigate to the Kafka directory.
Edit the server.properties file and replace the log.dirs property with a directory path where you want to store Kafka logs.
Start Kafka by running the following command from the Kafka directory: bin\windows\kafka-server-start.bat config\server.properties

Linux

Extract the Kafka archive you downloaded to a directory of your choice.
Navigate to the Kafka directory and open the config folder.
Edit the zookeeper.properties file and replace the dataDir property with a directory path where you want to store ZooKeeper data.
Start ZooKeeper by running the following command from the Kafka directory:bin/zookeeper-server-start.sh config/zookeeper.properties
Open a new terminal window and navigate to the Kafka directory.
Edit the server.properties file and replace the log.dirs property with a directory path where you want to store Kafka logs.
Start Kafka by running the following command from the Kafka directory:bin/kafka-server-start.sh config/server.properties

STEP 2 : Running python script

Run kafka server

pip install -r requirements.txt

How to use producer

go to terminal where the python code producer.py is and type python producer.py

How to use consumer (producer must be running in order to use this command)

Use consumer to run stream of fake heart data

go to terminal where the consumer.py is and type python consumer.py stream

Use consumer to create dataset of fake heart data (dataset.json must be present in order to run this command)

(dataset.json is automatically formed when running stream using python consumer.py stream command)

go to terminal where the consumer.py is and type python consumer.py dataset
