Learn how to write, tune, and port SQL queries and other statements for a
Big Data environment, using Impala—the massively parallel processing
SQL query engine for Apache Hadoop. The best practices in this practical
guide help you design database schemas that not only interoperate with
other Hadoop components, and are convenient for administers to manage
and monitor, but also accommodate future expansion in data size and
evolution of software capabilities.
Written by John Russell,
documentation lead for the Cloudera Impala project, this book gets you
working with the most recent Impala releases quickly. Ideal for database
developers and business analysts, the latest revision covers analytics
functions, complex types, incremental statistics, subqueries, and
submission to the Apache incubator.
Getting Started with Impala

from its consulting engagements with customers.
