Introduction

Apache Kafka is a distributed event streaming platform used to build real-time data pipelines and streaming applications. It is designed to handle high-throughput, fault-tolerant, and low-latency data streams, enabling organizations to process large amounts of data in real time. Kafka’s core capabilities include publishing, subscribing, storing, and processing streams of records in a fault-tolerant manner, making it ideal for use cases such as data integration, event-driven architectures, log aggregation, and real-time analytics.

Kafka is based on a distributed architecture that can scale horizontally, making it highly suitable for enterprise-grade solutions requiring fault tolerance and scalability. By allowing the handling of high-volume event data, it helps businesses integrate, process, and analyze data in real-time, enabling quick decision-making and efficient operations.

Prerequisites

• Basic understanding of messaging systems and event-driven architectures.
• Familiarity with concepts such as publish-subscribe, streams, and topics.
• Basic knowledge of programming languages such as Java, Python, or Scala (optional for deeper integration).
• Understanding of distributed systems and clustering concepts.
• A development or cloud environment with the capability to install and configure Kafka.
