Getting Started with Storm

Preface

If you’re reading this, it’s because you heard about Storm somehow, and you’re interested in better understanding what it does, how you can use it to solve various problems, and how it works.

This book will get you started with Storm in a very straightforward and easy way.

The first few chapters will give you a general overview of the technologies involved, some concepts you should understand so we all speak the same language, and how to install and configure Storm. The second half of the book will get you deep into spouts, bolts and topologies (more about these in a moment). The last few chapters address some more advanced features that we consider very important and interesting, like using Storm with languages that are not JVM-based.
