What better way to explain these concepts than by using a pizza takeaway shop as reference? Who doesn't love pizza? :blush: CQRS in a Nutshell CQRS is an architectural pattern that separates the responsibility of executing commands that change data (write operations) from the responsibility of retrieving data (read operations). In a traditional application, a single model is used for both reading and writing data. However, in a CQRS architecture, separate models are used for each type of operation. This allows for: - Better segregation of concerns - Optimization of read and write performance - More flexibility in handling complex data retrieval and manipulation requirements CQRS is often used in highly scalable, complex systems where there is a need for high performance, flexible data retrieval, and efficient transaction handling. It is used in a variety of domains, including finance, e-commerce, and gaming. A lean approach to implement the CQRS pattern is by using Apache Kafka as its underlying event store. The basic idea behind using Kafka for CQRS is to have separate Kafka topics for commands and queries, which allows for a clear separation of the write and read models. Here are the steps to implement CQRS with Apache Kafka: 1.
