Read activity tends to be more frequent than writing, thus you can reduce response latency by placing read data sources in strategic geolocations for better performance. Separating write from read activity leads to more efficient scaling of storage capacity based on real-world usage. Cons Supporting...
Current State Backing: Pros : 1) Easier to retrofit on a legacy project; 2)Well known technology/tools/skill sets; 3)Easier sell for an organization. Cons: 1) Dual models cost more and contain risk; 2) Non-Event Centric. Event Storage Backing: Pros: 1) Single Event Centric Model; 2)...
CQRS pros & consPros:better performance and scalability of your system. better concurrent access handling. better team scalability. less complex domain model and simple query model.Cons:read and write models must be kept in sync. maintenance and administration costs if you choose two different ...
Trade-offs of various view model options proposes some pros and cons for each of our options. As it happens, the allocation service at MADE.com does use "full-blown" CQRS, with a read model stored in Redis, and even a second layer of cache provided by Varnish. But its use cases are...

Pros and Cons of a Relationship-Free DbContext for Writes So what have I gained by separating the writing responsibilities from the querying responsibilities? It’s easy for me to see the downsides. I have more code to maintain. More important, EF won’t magically update graphs for me. I...
(big ball of mud), and based on suggestions from the audience we explored different solutions which might improve the solution. Whatever suggestions we threw at him, he always had a thoroughly considered answer describing pros and cons with the suggested solution.He obviously has a lot of ...
Segregation I think that the time has come for some clarification. Some have been tying it together to Event Sourcing. Most have been overlaying their previous layered architecture assumptions on it. Here I hope to identify CQRS itself, and describe in which places it can connect to other ...
Domain Driven Design Quickly - Domain Driven Design Quickly is a short, quick-readable summary and introduction to the fundamentals of DDD. Effective Aggregate Design - In this three-part series, Vaughn Vernon walks through some common design pitfalls, discusses the pros and cons of various aggrega...
Command Query Responsibility Segregation (CQRS)is simply the creation of two objects where there was previously only one. The separation occurs based upon whether the methods are a command or a query (the same definition that is used by Meyer in Command and Query Separation, a command is any ...
