Introduction to Apache Kafka: Essential Guide for Beginners

Apache Kafka is an open-source distributed event streaming platform used by thousands of companies for high-performance data pipelines, streaming analytics, data integration, and mission-critical applications.

Why Use Kafka?

Kafka is chosen for its ability to handle real-time data feeds. Kafka is fast, scalable, durable, and fault-tolerant, making it a cornerstone in the modern data ecosystem.

Core Concepts

• Producer: An application that sends messages to Kafka.
• Consumer: An application that reads messages from Kafka.
• Broker: A Kafka server that stores messages submitted by producers.
• Topic: A category or feed name to which records are published.
• Partition: A horizontal scaling mechanism that allows Kafka to split topics across multiple servers.
