Introduction

Welcome to Chapter 16! So far, we’ve explored the core concepts of SpaceTimeDB, built real-time applications, and even delved into performance and security. But what happens when your application grows, and your initial data model no longer fits your evolving needs? This is where schema evolution and data migrations come into play.

In this chapter, we’ll tackle the crucial, yet often overlooked, aspects of managing change in your SpaceTimeDB projects. We’ll learn how to gracefully adapt your database schema over time without disrupting existing data or live applications. We’ll also explore different strategies for migrating data when your schema changes require transforming existing information. Finally, we’ll dive into advanced design patterns like Event Sourcing and CQRS, showing how SpaceTimeDB’s unique architecture naturally supports them, helping you build even more robust and scalable systems.
