What is CQRS design pattern?

Command and Query Responsibility Segregation (CQRS) is a pattern that segregates the operations that read data (queries) from the operations that update data (commands) by using separate interfaces. This means that the data models used for querying and updates are different. For more click on the below link: https://docs.microsoft.com/en-us/azure/architecture/patterns/cqrs

Command and Query Responsibility Segregation (CQRS) is a pattern that segregates the operations that read data (queries) from the operations that update data (commands) by using separate interfaces. This means that the data models used for querying and updates are different. In simple words, Create and update data commands and while fetching(read) data queries are used so both will be separate from each other.

Command and Query Responsibility Segregation (CQRS) is a pattern that segregates the operations that read data (queries) from the operations that update data (commands) by using separate interfaces.

Segregate operations that read data from operations that update data by using separate interfaces. This can maximize performance, scalability, and security. Supports the evolution of the system over time through higher flexibility, and prevents update commands from causing merge conflicts at the domain level.

CQRS is Command Query Responsibility Segregation Pattern. It helps in separating the concerns such as Reads from Writes. Hence you have more flexibility to scale your specific concerns such as if you have lot of users visiting you portal but very few posting contents then you need scaled read a low profile write
