BIG DATA
ABOUT THE BOOK
Web‐scale applications like social networks, real‐time
analytics, or e‐commerce sites deal with a lot of data,
whose volume and velocity exceed the limits of
traditional database systems. These applications
require architectures built around clusters of
machines to store and process data of any size, or
speed. Fortunately, scale and simplicity are not
mutually exclusive.
This book requires no previous exposure to large‐
scale data analysis or NoSQL tools. Familiarity with
traditional databases is helpful.

What’s Inside
 Introduction to big data

systems
 Real-time processing of web-

scale data
 Tools like Hadoop, Cassandra,

and Storm
 Extensions to traditional

database skills

Authors: Nathan Marz
with James Warren

SUMMARY
Big Data teaches you to build big data systems using an architecture that takes advantage of clustered hardware
along with new tools designed specifically to capture and analyze web‐scale data. It describes a scalable, easy‐to‐
understand approach to big data systems that can be built and run by a small team. Following a realistic example, this
book guides readers through the theory of big data systems, how to implement them in practice, and how to deploy
and operate them once they're built.

ABOUT THE AUTHORS
Nathan Marz is the creator of Apache Storm and the originator of the Lambda Architecture
for big data systems. James Warren is an analytics architect with a background in machine
learning and scientific computing.
