Event Sourced Architecture: A Deep Dive

This 90-minute podcast episode provides a comprehensive deep dive into Event Sourcing architecture, beginning with fundamental definitions rooted in Domain Driven Design and exploring how this pattern records every state change in an application. Learn about the nature of events, real-world implementation strategies, and the balance between benefits and challenges of this approach. Discover practical aspects including storage costs, computational expenses, and performance optimization through snapshotting. The discussion covers essential related concepts like event ownership, Command Query Responsibility Segregation (CQRS), and ensuring data consistency with Apache Kafka. Explore Kafka's performance mechanisms, its role as an event store, and the transition from Zookeeper to KRaft for cluster coordination. Compare alternatives like using Postgres' Write-Ahead Logging as an event store, examine industry use cases, and get practical advice for common implementation problems. By the conclusion, gain clarity on whether Event Sourcing is the right architectural choice for specific project requirements.
