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.

Deep Dive into Kafka Producers

In previous chapters, you have learned about messaging systems and Kafka architecture. While it is a good start, we will now take a deeper look into Kafka producers. Kafka can be used as a message queue, message bus, or data storage system. Irrespective of how Kafka is used in your enterprise, you will need an application system that can write data to the Kafka cluster. Such a system is called a producer. As the name suggests, they are the source or producers of messages for Kafka topics. Kafka producers publish messages as per Kafka protocols defined by the makers of Kafka. This chapter is all about producers, their internal working, examples of writing producers using Java or Scala APIs, and some of the best practices of writing Kafka APIs. We will cover the following topics in this chapter:

  • Internals of a Kafka producer
  • The Kafka Producer API...
