Design Microservices Architecture with Patterns and Principles - CQRS with Event Sourcing Pattern

The video tutorial explains the event sourcing pattern, highlighting its integration with secure patterns and CQRS design. It emphasizes storing events in a write database as the source of truth, while read databases provide materialized views. The event store records all changes sequentially, allowing for historical data reconstruction. A practical example of a shopping cart in an ecommerce application illustrates the concept. The tutorial also addresses the complexity and eventual consistency challenges associated with event sourcing.
