Introduction to Kafka

Welcome to the "Introduction to Kafka" lesson! In this lesson, we will provide you with an overview of Kafka and its key concepts.

What is Kafka?

Kafka is a distributed event streaming platform designed to handle high volumes of data in real-time. It provides a publish-subscribe model, where producers publish data to Kafka topics, and consumers subscribe to those topics to consume the data. Kafka is known for its scalability, reliability, and performance.

Key Concepts

Topics

In Kafka, data is organized into topics. A topic is a category or feed name to which records are published. Each topic can have one or more partitions.

Producers

Producers are applications that publish data to Kafka topics. They can be written in different programming languages, including Java.

Consumers

Consumers are applications that subscribe to Kafka topics and consume the published data. Consumers read from one or more partitions of a topic.

Brokers

Brokers are the servers in a Kafka cluster that manage the storage and replication of data. They handle the publishing and consuming of messages from producers and consumers.

ZooKeeper

ZooKeeper is a centralized service used by Kafka for maintaining configuration information, providing distributed synchronization, and detecting failures.

Now that you have a high-level understanding of Kafka and its key concepts, let's dive deeper into each topic and explore Kafka in more detail.

class Main {

  public static void main(String[] args) {

    // replace with your Java logic here

    System.out.println("Hello Kafka!");

  }
