How Can You Ask Questions of Your Big Data and Quickly Get
Answers?
Google BigQuery is a tool that enables you to run SQL queries over your Big
Data. It fans out query requests to thousands of servers, reads from tens or
hundreds of thousands of disks at once, and can return answers to complex
questions within seconds. This topic describes how BigQuery can achieve
such good performance and how you can use it to run queries on your own
data.
Summary
This chapter briefly documented the history of Google's Big Data systems
and provided a survey of scale-out technologies, both at Google and
elsewhere. It set the stage for BigQuery by describing an unfulfilled Big
Data analytics niche. This chapter deliberately didn't mention BigQuery very
much, however; Chapter 2 should answer all your questions about what
BigQuery is and what it can do.
