Building Data Streaming Applications with Apache Kafka

By: Chanchal Singh, Manish Kumar

Overview of this book

Apache Kafka is a popular distributed streaming platform that acts as a messaging queue or an enterprise messaging system. It lets you publish and subscribe to a stream of records, and process them in a fault-tolerant way as they occur. This book is a comprehensive guide to designing and architecting enterprise-grade streaming applications using Apache Kafka and other big data tools. It includes best practices for building such applications, and tackles some common challenges such as how to use Kafka efficiently and handle high data volumes with ease. This book first takes you through understanding the type messaging system and then provides a thorough introduction to Apache Kafka and its internal details. The second part of the book takes you through designing streaming application using various frameworks and tools such as Apache Spark, Apache Storm, and more. Once you grasp the basics, we will take you through more advanced concepts in Apache Kafka such as capacity planning and security. By the end of this book, you will have all the information you need to be comfortable with using Apache Kafka, and to design efficient streaming data applications with it.

Building Streaming Applications Using Kafka Streams

In the previous chapter, you learned about Kafka Connect and how it makes a user's job simple when it comes to importing and exporting data from Kafka. You also learned how Kafka Connect can be used as an extract and load processor in the ETL pipeline. In this chapter, we will focus on Kafka Stream, which is a lightweight streaming library used to develop a streaming application that works with Kafka. Kafka Stream can act as a transformer in the ETL phase.

We will cover the following topics in this chapter:

  • Introduction to Kafka Stream
  • Kafka Stream architecture
  • Advantages of using Kafka Stream
  • Introduction to KStream and KTable
  • Use case example
