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.

Decommissioning brokers

Kafka is a distributed and replicated messaging system. Decommissioning brokers can become a tedious task sometimes. In lieu of that, we thought of introducing this section to keep you informed about some of the steps you should perform for decommissioning the broker.

You can automate this using any scripting language. In general, you should perform the following steps:

  1. Log in to the Zookeeper shell, and from there, collect the relevant broker information based on the broker IP or hostname.
  2. Next, based on the broker information collected from Zookeeper, you should gather information about which topics and partition data need to be reassigned to different brokers. You can use Kafka topic shell-based utilities to gather such information. Basically, topic partitions that require reassignment are identified with leader and replicas values that are equal to...
