Thanks for your reply. It would be great to have an architectural one-size-fits-all. Wouldn't you agree? Unfortunately, what is and what isn't a good idea depends on the context.
So, what would you recommend? What do you think are the heuristics on when to apply CQRS and when not to apply CQRS as a global architecture? And how do you define a "global architecture"? (These concepts have different meanings to many people.) How static/evolutionary is your architecture? Etc. etc.
Looking forward to your response!
