Event Sourcing & CQRS

Picture this: It is 2:00 AM on Black Friday. Your checkout service just crashed because five microservices locked the exact same database row. When you inspect the database tomorrow, you see a balance of $0.00, but an UPDATE statement overwrote the past. Did the customer empty their cart, or did a bug wipe it? You will never know.

We have all built this distributed monolith. I spent years fighting these fires before realizing the problem wasn't our code-it was how we modeled time and state. This book shows you how to build software that never forgets.

No fluff-just actionable, battle-tested patterns:

• Event Sourcing Mechanics: Master append-only logs, rehydration, and schema upcasting.
• CQRS Deconstructed: Isolate write-side intent from read-side queries.
• Distributed Workflows: Build resilient Sagas without two-phase commits.
• Production Realities: Navigate trade-offs between Kafka, RabbitMQ, and KurrentDB.
• The Human Element: Reorganize teams using Team Topologies to conquer Conway's Law.

This book is for software architects, backend developers, system engineers, and tech leads. Whether you feel limited by CRUD monoliths, struggle with microservice consistency, or are leading an enterprise modernization, this is your roadmap. You don't need prior Event Sourcing experience-just a desire to build resilient systems.

Stop building distributed monoliths that overwrite history and buckle under scale. Grab your copy today, transform your architectural mindset, and start building event-driven systems that stand the test of time!
