Design Microservices Architecture with Patterns and Principles - CQRS - Command Query Responsibility Segregation Pattern

The video tutorial explains the Command Query Responsibility Segregation (CQRS) pattern, which separates read and write operations in microservices to improve performance and scalability. It highlights the challenges of using a single database for both operations and suggests using different databases for reading and writing. The tutorial discusses the benefits of CQRS, such as avoiding complex queries and database locks, and introduces the concept of eventual consistency through asynchronous communication. The video also touches on the use of NoSQL and relational databases to optimize data handling.
