All you need to start building useful software.

David Luckham, author of the Foreword

Event Processing in Action is a ground-breaking book that shows you how to use, design, and build event processing applications. It follows a detailed example to present the concepts and show you the how-tos of both architecture and implementation. The book and its accompanying website introduce the leading free and commercial tools available, along with several language implementations and many examples.

About the Technology

Event processing apps collect, analyze, and react to events as they occur. They recognize event patterns — from the obvious to the complex, even predicting outcomes such as power shortages or customer dissatisfaction — and respond to them accordingly. In some applications, such as financial trading, fast reaction times are a must.
