Design Microservices Architecture with Patterns and Principles - How to Sync Read and Write Databases in CQRS?

The video tutorial discusses the SQLS design pattern, focusing on synchronizing read and write databases using event-driven architecture. It highlights the challenges of eventual consistency due to asynchronous communication and suggests using replicas and materialized views for improved performance. The tutorial also covers the CQRS design pattern, which separates command and query databases, allowing independent scaling. Event sourcing is recommended for maintaining consistency, and the video emphasizes the importance of understanding both CQRS and event sourcing for effective database management.
