Chapter 1. Building a High-Throughput Messaging System with Apache Kafka

Apache Kafka is a fast, scalable, durable, fault-tolerant publish-subscribe messaging system. Common use cases include:

  • Stream processing

  • Messaging

  • Website activity tracking

  • Metrics collection and monitoring

  • Log aggregation

  • Event sourcing

  • Distributed commit logging

Kafka works with Apache Storm and Apache Spark for real-time analysis and rendering of streaming data. The combination of messaging and processing technologies enables stream processing at linear scale.

For example, Apache Storm ships with support for Kafka as a data source using Storm’s core API or the higher-level, micro-batching Trident API. Storm’s Kafka integration also includes support for writing data to Kafka, which enables complex data flows between components in a Hadoop-based architecture. For more information about Apache Storm, see the Storm User Guide.
