CQRS
Command Query Responsibility Segregation
Definition
CQRS separates read (query) and write (command) operations into distinct models, allowing each to be optimized independently. The write model handles state changes and enforces business rules; a separate read model (often a denormalized projection) serves queries efficiently.
CQRS is commonly paired with Event Sourcing and enables independent scaling of read and write workloads.

Every CISO is asking these three questions. We answer them with facts, not guesses, from repository to runtime.
