I want to say thanks to my editors Cheryl Dsa and Dinesh Pawar. Without their effort and patience, it would not have been possible to write this book. I also thank my acquisition editor, Varsha Shetty, who believed in this project from the beginning. And finally, I want to thank all the heroes who contribute (often anonymously and without profit) to open source projects, specifically Apache Kafka. An honorable mention for those who build the connectors of this technology, and especially the Confluent Inc. crew.
