Work Queue Patterns

Master Deferred and Distributed Work in Node

About the Book

Most applications have some type of work that can be performed independently from the client request cycle. You can defer these types of work into a memory queue or, to survive crashes, a persisted queue. A distributed queue separates the work producer from the work consumer, allowing you to perform work on a different process.

This book will show you how to create and consume work in a local or distributed environment using Node.
