SQLite in Production: Design, Tune, Replicate, and Deploy High-Performance Systems with WAL, FTS5, JSONB, Litestream, LiteFS, Turso, Cloudflare D1

SQLite is no longer just a lightweight, embedded database-it is rapidly becoming one of the most powerful and practical foundations for modern application architecture.In SQLite in Production: Design, Tune, Replicate, and Deploy High-Performance SQLite Systems with WAL, FTS5, JSONB, Litestream, LiteFS, Turso, and Cloudflare D1, you will learn how to take SQLite far beyond its traditional use cases and build real, production-grade systems that are fast, reliable, and operationally efficient.This book is not theoretical. It is a hands-on, practice-driven guide designed for engineers who want to use SQLite in serious environments-APIs, SaaS platforms, edge deployments, local-first applications, and distributed systems.You will learn how to: - Design high-performance schemas using STRICT tables, generated columns, and hybrid JSON models- Optimize queries and indexing strategies using real workload patterns and EXPLAIN analysis- Enable concurrent reads and reliable writes with WAL mode and transaction tuning- Build full-text search systems using FTS5 with ranking, filtering, and production-ready query patterns- Implement backup, replication, and recovery strategies with Litestream and LiteFS- Deploy SQLite in Docker, cloud, and edge environments using Turso and Cloudflare D1- Diagnose and fix real-world issues such as lock contention, slow queries, and data corruption- Operate SQLite with confidence using observability, maintenance, and failure recovery runbooksAt the heart of this book is a complete end-to-end capstone project, where you will build, deploy, replicate, and operate a production-ready SQLite system-combining API design, search, sync workflows, and disaster recovery into a single cohesive architecture.Unlike typical SQLite resources that stop at basic usage, this book focuses on real production concerns: - performance under load- data durability and recovery- deployment discipline- security and governance- operational reliabilityWhether you are a backend engineer, DevOps practitioner, or indie SaaS builder, this guide equips you with the knowledge and practical patterns needed to confidently use SQLite as a primary database in modern systems.If you are ready to move beyond "SQLite for prototyping" and start building high-performance, production-grade applications with SQLite at the core, this book will show you exactly how.
