The Raspberry Pi Engineering Blueprint

Does your database keep you up at night - or does it finally feel like something you actually understand?

Be honest. Have you ever stared at a query that used to run in milliseconds and now takes eleven seconds, with absolutely no idea why? Have you added an index just to "see if it helps," crossed your fingers, and moved on without ever understanding what actually happened underneath? If any of that sounds familiar, you're not alone - and this book was written specifically to close that gap once and for all.

PostgreSQL has quietly become one of the most trusted database engines in the world, powering everything from scrappy startups to massive enterprise systems. But here's the problem: most resources either hand you a syntax cheat sheet dressed up as a book, or they drown you in internals you can't actually apply to your job on Monday morning. This book takes a different path. It's built around real engineering judgment - not just what to type, but why it works, when it breaks, and how to fix it with confidence.

So what will you actually walk away with?

You'll finally understand what's happening beneath the surface - how the engine manages memory, writes to disk safely, and keeps dozens of transactions running at once without stepping on each other. You'll stop guessing at query performance and start reading execution plans like a professional, diagnosing slow queries in minutes instead of hours. You'll learn to design schemas that hold up under real production pressure, not just in a tutorial with ten rows of sample data.

Curious about keeping your systems running when something inevitably goes wrong? This book walks you through replication, failover, backups, and disaster recovery in plain language, with the kind of step-by-step reasoning you'd expect from a mentor sitting next to you, not a dry reference manual. Worried about security and compliance? You'll learn how to lock down access properly, encrypt sensitive data, and build an audit trail that actually holds up under scrutiny.

And because the world of data has changed dramatically in the last few years, this book doesn't stop at traditional rows and columns. You'll explore how to build modern search experiences, work with semi-structured data, and even implement AI-powered retrieval systems that ground a language model's answers in your own real data - all using the same database engine you're already running, without bolting on a separate specialized system you now have to babysit.

Whether you're a backend developer tired of treating the database as a mysterious black box, a data engineer who wants queries that don't fall over the moment real traffic shows up, or someone working toward a serious administration or platform engineering role, this book meets you where you are and takes you somewhere genuinely useful.

Every chapter is built around real problems you'll actually face - complete with working code, clear explanations of the reasoning behind each decision, and honest discussion of tradeoffs, because no serious engineering advice comes without one. Nothing here is filler. Nothing here is recycled documentation with different formatting.

So - are you ready to stop fighting your database and start actually understanding it?

If the answer is yes, this book is exactly where you should start.
