How To Stop Zookeeper In Kafka In Windows

In the modern world, businesses take to rely on Existent-time Data for quickly making data-driven decisions and serving customers better. Even so, often companies use data from the Static Database Server that contains information about users' Historical Data. While Batch Processing operations can be advantageous for edifice several information-driven solutions, making use of generated data in existent-time tin can provide you with an edge in the competitive market.

Currently, many companies and businesses are building and upgrading applications based on real-fourth dimension user preferences. Real-time customers' data can be used to enhance the ML Models for seamlessly building Recommendation Systems co-ordinate to each customer appointment. Today, in that location are several Information Streaming platforms available for handling and processing real-time infinite or continuous information. 1 such Data Streaming Platform is Kafka, which allows you lot to access or consume real-fourth dimension data to build event-driven applications.

What is Kafka?

Epitome Source

Kafka is a Distributed Streaming platform that allows you to develop Real-time Event-driven applications. In other words, Kafka is a High-Performance Message Processing system that enables you to process and clarify a Continuous Stream of information for building existent-time Information Pipelines or Applications. Kafka was originally adult by Linkedin's Technology Team in 2010 for tracking various activity events generated on a LinkedIn webpage or app, such equally message exchanges, page views, ads presented, etc. However, in 2011, it was made Open-source via Apache Software Foundation, allowing organizations and users to access information that are streaming in real-fourth dimension for free.

Kafka is also called a Publish-subscribe Messaging System because information technology involves the action of publishing too as subscribing messages to and fro the Kafka server by producers and consumers, respectively. Such efficient capabilities permit Kafka to exist used by the nigh prominent companies worldwide. Based on a study, Kafka is beingness used by more than 20,500 organizations worldwide, including 80% of the Fortune 500 Companies similar Netflix, Airbnb, Uber, and Walmart. For instance, based on real-fourth dimension user engagements, Netflix uses Kafka to provide customers with instant recommendations that let them to sentinel similar genres or content.

Key Features of Kafka

• Existent-time Analytics: With Kafka, you can seamlessly perform analytics operations on data that is streaming in real-time. As a consumer, y'all can effectively filter and access the existent-time or continuous menses of data stored in a Kafka Server or Broker to perform whatsoever data-related operations based on the utilize cases.
• Fast: Every bit Kafka Decouples Information Streams, it has very low latency and a very loftier speed.
• Consistency: Kafka is highly capable of handling and processing trillions of data records per twenty-four hour period, including petabytes of data. Even though the data is vast and large, Kafka always maintains and organizes the occurrence order of each collected data. Such a feature allows users to finer access and consume specific data from a Kafka server or broker based on the utilise cases.
• High-Accurateness: Kafka maintains a high level of accuracy in managing and processing real-fourth dimension data records. With Kafka, you lot not only achieve high accuracy in organizing the streaming data but can besides perform analytics and prediction operations on the real-time data.
• Integrations: Kafka can integrate with other data-processing frameworks or services like Apache Spark, Apache Storm, Hadoop, and AWS. By integrating Kafka with such applications, y'all tin seamlessly comprise the advantages of Kafka into your Real-time Information Pipelines.
• Fault tolerance: Since Kafka replicates and spreads your data often to other Servers or Brokers, it is highly fault-tolerant and reliable. If one of the Kafka Servers fails, the data will be available on other servers from which you tin easily access the data.

4 Steps to Install Kafka on Windows

Here are the simple steps to Install Kafka on Windows:

• Prerequisites
• Download Kafka
• Install and Configure Kafka
• Starting Zookeeper and Kafka
• Testing Kafka past Creating a Topic

Prerequisites

Before installing Kafka, yous should take ii applications pre-installed in your local car.

• Java Development Kit (JDK): Java is the most needed prerequisite before installing Kafka on your figurer. You can install the JDK by downloading information technology from the official Oracle website. Select and download the advisable installer according to your system type, .i.e, 32 chip or 64 fleck. After downloading, you tin can run the installer by following the on-screen instructions. You should too configure the file path and Java_Home surroundings variables to enable your operating system to locate the Java utilities. Finally, test your JDK installation by running the command coffee -version in your control prompt.

• 7-Zilch or WinRAR:  7-Zip or WinRAR applications allow you to unzip or extract the downloaded Kafka files.

1) Install Kafka on Windows: Download Kafka

Image Source: Cocky

• To install Kafka on Windows, visit the official page of Apache Kafka and click on the "Download Kafka" push.

Image Source: Cocky

• Now, you volition be redirected to the downloading folio. You can then encounter the Binary Downloads pick. Under that, select the latest Kafka version that is Scala 2.13.

Image Source: Self

• Then, you lot will be taken to another webpage where you will take the straight download link for downloading your Kafka file.
• Click on the corresponding link. Now, Kafka is successfully downloaded.

2) Install Kafka on Windows: Install and Configure Kafka

• After downloading, excerpt or unzip the Kafka files. Move the extracted folder to any of your preferred directories for chop-chop accessing it from the command prompt.
• Now, you take to perform some configurations in the extracted Kafka files to properly install Kafka on Windows.
• Usually, extracted Kafka files take Zookeeper files that run simultaneously with Kafka for managing all the Clusters and Configurations of Kafka servers.
• Instead of storing them in default temp folders, you can configure both the Kafka and ZooKeeper files to store Kafka and ZooKeeper data in separate folders.

Image Source

• Create a new folder named "Data" inside the Kafka folder. Within the Data folder, create two carve up folders named "Kafka" and "Zookeeper."
• After creating separate folders for Kafka and Zookeeper, yous take to brand some changes in the configuration files for pointing to the newly created folders.
• For that, initially copy the file path of the Zookeeper folder created inside the data folder.

Image Source

• From the config folder present inside the extracted Kafka files, open the "Zookeeper.properties" file with whatever text editor applications like Notepad or Notepad++. In the opened file, replace your "datadir" location with the copied Zookeeper folder path, every bit shown in the above image. Brand certain y'all change the path with forwarding slashes instead of backward slashes. Finally, salve the file to update the changes made to the file configurations.
• After configuring the Zookeeper backdrop, you must configure the Kafka Server backdrop. For that, copy the file path of the Kafka Binder created inside the data folder.
• Open the server.properties file from the "Config" folder present inside the extracted Kafka files.

Image Source

• In the server.properties file, supervene upon the "logs.dirs" location with the copied Kafka folder path as shown in the above image. Make sure yous change the path with forward slashes instead of backward slashes. Supplant the backward slashes with frontwards slashes in the file path and salvage the file.
• Now, you take made the necessary changes and configurations to the Kafka files and are ready to ready and start Kafka on your computer.

These are the unproblematic steps to install Kafka on Windows.

iii) Install Kafka on Windows: Starting Zookeeper and Kafka

After configuring Zookeeper and Kafka, you lot have to start and run Zookeeper and Kafka separately from the command prompt window.

A) Starting Zookeeper

Open up the command prompt and navigate to the D:Kafka path. At present, type the beneath command.

          zookeeper-server-commencement.bat ....configzookeeper.properties        

Image Source

You can come across from the output that Zookeeper was initiated and bound to port 2181. By this, yous tin confirm that the Zookeeper Server is started successfully. Practice non shut the command prompt to keep the Zookeeper running.

B) Starting Kafka

Open up another command prompt window and type the beneath command.

          kafka-server-start.bat ....configserver.properties        

The Kafka Server has started successfully and is gear up for Streaming Data.

Now, both Zookeeper and Kafka have started and are running successfully. To confirm that, navigate to the newly created Kafka and Zookeeper folders. When y'all open the respective Zookeeper and Kafka folders, you can observe that certain new files have been created inside the folders.

4) Install Kafka on Windows: Testing Kafka by Creating a Topic

Every bit you take successfully started Kafka and Zookeeper, you lot tin test them by creating new Topics and then Publishing and Consuming messages using the topic name. Topics are the virtual containers that store and organize a stream of messages under several categories called Partitions. Each Kafka topic is always identified by an capricious and unique proper name across the entire Kafka cluster.

In the below steps, you will acquire how to create topics:

For creating a topic, open a new command prompt and write the below command:

          .binwindowskafka-topics.bat --create --zookeeper localhost:2181 --replication-factor 1 --partitions 1 --topic TestTopic        

In the higher up command, TestTopic is the unique name given to the Topic, and zookeeper localhost:2181 is the port that runs Zookeeper. After the execution of the control, a new topic is created successfully.

When you demand to create a new Topic with a different proper noun, yous can supervene upon the aforementioned code with another topic name. For example:

          .binwindowskafka-topics.bat --create --zookeeper localhost:2181 --replication-gene 1 --partitions 1 --topic NewTopic        

In the command, you have simply replaced the topic name while other command parts remain the same. To list all the available topics, you can execute the below control:

          .binwindowskafka-topics.bat --list --zookeeper localhost:2181        

By this simple Topic Creation method, you can confirm that Kafka is successfully installed on Windows and is working fine. Further, you lot can add and publish messages to the specific topic so eat all messages from the same topic.

Decision

In this commodity, you take learned about Kafka and the distinct features of Kafka. Y'all accept as well learned how to Install Kafka on Windows, create Topics in Kafka, and examination whether your Kafka is working correctly. Since Kafka can perform more high-end operations, including Real-time Data Analytics, Stream Processing, edifice Data Pipelines, Activity Tracking, and more, it makes one of the go-to tools for working with streaming information.
