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.

Kafka Connect common use cases

You have learned about Kafka Connect in detail. We know Kafka Connect is used for copying data in and out of Kafka.

Let's understand a few common use cases of Kafka Connect:

  • Copying data to HDFS: User wants to copy data from Kafka topics to HDFS for various reasons. A few want to copy it to HDFS just to take a backup of the history data, others may want to copy it to HDFS for batch processing. However, there are already many open source tools available, such as Camus, Gobblin, Flume, and so on, but maintaining, installing, and running these jobs takes more effort than what Kafka Connect provides. Kafka Connect copies data from topics in parallel and is capable of scaling up more if required.
  • Replication: Replicating Kafka topics from one cluster to another cluster is also a popular feature offered by Kafka Connect. You may want to replicate...
