Unlike traditional information systems which work by issuing requests and waiting for responses, event-driven systems are designed to process events as they occur, allowing the system to observe, react dynamically, and issue personalized data depending on the recipient and situation.
Event Processing in Action introduces the major concepts of event-driven architectures and shows how to use, design, and build event processing systems and applications. Written for working software architects and developers, the book looks at practical examples and provides an in-depth explanation of their architecture and implementation. Since patterns connect the events that occur in any system, the book also presents common event-driven patterns and explains how to detect and implement them. Throughout the book, readers follow a comprehensive use case that incorporates all event processing programming styles in practice today.
Purchase of the print book comes with an offer of a free PDF, ePub, and Kindle eBook from Manning. Also available is all code from the book.
This is a good introductory book on event processing for someone, who is generally fresh to event processing. Most of this book is focused around principles of event processing such as what is a publisher, event processing agent or subscriber. If you are looking for some information on recovery or message ordering or some advanced pattern matching, you could be disappointed with this position. Those topics are a very little covered in the last part of this book (Pragmatics), which is the most entertaining section in my opinion. A big plus for giving references to external resources after each chapter, which allow to pursue some aspects of event processing further in more details.
Lots of valuable information but my current gig doesn't have a problem that requires an event processing solution which may explain why I didn't read it as fast as I normally do. The book does a great job of showing us the event processing landscape and convinced me that trying to roll your own solution is a silly, silly idea. If you ever want to know what event processing is this is a great book to pick up.
