What is Kafka?

Epitome Source

Kafka is a Distributed Streaming platform that allows y'all to develop Real-fourth dimension Event-driven applications. In other words, Kafka is a High-Performance Bulletin Processing system that enables you to process and clarify a Continuous Stream of information for building existent-time Data Pipelines or Applications. Kafka was originally developed by Linkedin's Engineering Team in 2010 for tracking various activity events generated on a LinkedIn webpage or app, such every bit bulletin exchanges, page views, ads presented, etc. Nonetheless, in 2011, it was fabricated Open up-source via Apache Software Foundation, allowing organizations and users to access data that are streaming in existent-time for complimentary.

Kafka is also chosen a Publish-subscribe Messaging Organization because information technology involves the action of publishing equally well as subscribing letters to and fro the Kafka server by producers and consumers, respectively. Such efficient capabilities allow Kafka to be used by the most prominent companies worldwide. Based on a written report, Kafka is existence used past more than twenty,500 organizations worldwide, including fourscore% of the Fortune 500 Companies like Netflix, Airbnb, Uber, and Walmart. For instance, based on real-time user engagements, Netflix uses Kafka to provide customers with instant recommendations that allow them to watch similar genres or content.

Key Features of Kafka

Existent-time Analytics: With Kafka, you lot can seamlessly perform analytics operations on data that is streaming in real-time. As a consumer, y'all can finer filter and access the existent-time or continuous menstruum of data stored in a Kafka Server or Broker to perform any 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 information records per mean solar day, including petabytes of data. Even though the data is vast and large, Kafka always maintains and organizes the occurrence order of each nerveless information. Such a feature allows users to effectively access and eat specific data from a Kafka server or broker based on the utilize cases.
High-Accuracy: Kafka maintains a high level of accuracy in managing and processing existent-time data records. With Kafka, yous not but achieve loftier accuracy in organizing the streaming data but tin also perform analytics and prediction operations on the real-time data.
Integrations: Kafka tin can integrate with other data-processing frameworks or services similar Apache Spark, Apache Storm, Hadoop, and AWS. Past integrating Kafka with such applications, you can seamlessly comprise the advantages of Kafka into your Real-time Data Pipelines.
Mistake tolerance: Since Kafka replicates and spreads your data frequently to other Servers or Brokers, information technology is highly mistake-tolerant and reliable.

Install Kafka on Windows - Data folder — Image Source

Create a new folder named "Data" within the Kafka folder. Inside the Data folder, create two separate folders named "Kafka" and "Zookeeper."
After creating separate folders for Kafka and Zookeeper, y'all have to make 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 information folder.

Install Kafka on Windows - Zookeeper Folder Path — Image Source

From the config folder present within the extracted Kafka files, open the "Zookeeper.properties" file with any text editor applications like Notepad or Notepad++. In the opened file, replace your "datadir" location with the copied Zookeeper folder path, equally shown in the in a higher place prototype. Make sure you alter the path with forwarding slashes instead of backward slashes. Finally, save the file to update the changes made to the file configurations.
Subsequently configuring the Zookeeper properties, you must configure the Kafka Server properties. For that, copy the file path of the Kafka Binder created inside the data folder.
Open up the server.properties file from the "Config" binder nowadays inside the extracted Kafka files.

You can come across from the output that Zookeeper was initiated and bound to port 2181. Past this, you tin can confirm that the Zookeeper Server is started successfully. Do not close the command prompt to keep the Zookeeper running.

B) Starting Kafka

Open another command prompt window and type the below command.

          kafka-server-get-go.bat ....configserver.properties

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

Now, both Zookeeper and Kafka have started and are running successfully. To ostend that, navigate to the newly created Kafka and Zookeeper folders. When yous open up the respective Zookeeper and Kafka folders, you can notice that certain new files have been created inside the folders.

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

Every bit you have successfully started Kafka and Zookeeper, you lot can exam them by creating new Topics and so Publishing and Consuming messages using the topic name. Topics are the virtual containers that store and organize a stream of letters under several categories chosen Partitions. Each Kafka topic is ever identified past an arbitrary and unique name across the entire Kafka cluster.

In the below steps, y'all volition learn 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-gene 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. Afterward the execution of the control, a new topic is created successfully.

When you need to create a new Topic with a unlike name, you can replace the same code with another topic name. For example:

          .binwindowskafka-topics.bat --create --zookeeper localhost:2181 --replication-factor one --partitions ane --topic NewTopic

In the control, you have only replaced the topic name while other control parts remain the aforementioned. To listing all the available topics, y'all can execute the below command:

          .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 can add and publish messages to the specific topic and then consume all messages from the same topic.

Conclusion

In this commodity, y'all have learned almost Kafka and the distinct features of Kafka. You lot have also learned how to Install Kafka on Windows, create Topics in Kafka, and exam whether your Kafka is working correctly. Since Kafka can perform more than high-end operations, including Real-fourth dimension Data Analytics, Stream Processing, building Data Pipelines, Action Tracking, and more, it makes 1 of the get-to tools for working with streaming data.
