SQL That Scales: Queries, Indexes, and Performance You Can Prove

By: Hawthorn, Amara

Most SQL books stop at syntax. This one starts where production pain begins. You'll learn how databases actually execute queries, how indexes truly work under the hood, and how to measure performance with evidence-not opinions. Through real-world examples, execution plans, and repeatable experiments, this book shows you how to turn slow, fragile queries into fast, predictable systems that scale with confidence.

Whether you're tuning a single query or designing data access for millions of users, SQL That Scales teaches you how to think like the optimizer, choose the right indexes, and validate every performance decision with proof. No cargo-cult advice. No magical thinking. Just SQL that holds up under load.

Inside you'll learn how to:

Read and reason about execution plans like a pro

Design indexes that improve performance without hidden tradeoffs

Write queries that stay fast as data volume grows

Measure and prove performance improvements using real metrics

Avoid common scaling traps that silently kill throughput

If you care about performance, reliability, and building systems that won't collapse at scale, this is the SQL book you've been waiting for.
