Explore the pitfalls and patterns of Command/Query Responsibility Segregation (CQRS) in this comprehensive conference talk from NDC Oslo 2023. Discover why CQRS can sometimes increase system complexity without delivering performance benefits. Learn where to apply CQRS effectively in projects and, more crucially, where to avoid its implementation. Delve into topics such as command query separation, domain models, architecture, standard and simple CQRS, private vs public data, vertical slice architecture, race conditions, optimistic concurrency, connection pools, and advanced composition. Gain insights on best practices and solutions to common CQRS problems to optimize your development approach.
