How Query Engines Work

February 27, 2020

Over the past decade I’ve spent a fair bit of time either building query engines or building integrations with query engines so I decided to write an introductory book on the subject.

The book walks through every step of building a SQL query engine in Kotlin with full source code available in a companion github repository. Most of the book is programming-language agnostic and Kotlin was chosen for the code examples due to its conciseness and readability. The concepts should be easily translatable to other programming languages.

The book is now available for purchase from leanpub.com.
