My Event handling implementation for my latest CQRS / Event Sourcing project is coming along nicely... using .Net Core, Reactive Extensions, Observables, ConnectableObservables and Redis with ProtoBuf-net for serialisation (testing different options for that). As an FYI, the test displayed in the images is using an Azure VM to run the Event Producer and Event Consumer with 10 concurrent event subscribers, and a very humble $16 a month Standard A0 (1 core, 0.75 GB memory) VM to run Redis, and a *very* simple message, just to test event ordering.

Sunday evening take: One thing I dislike about working in software development over all these years, is that so much time is spent arguing over software ideology, as if there is an absolute perfection or one true way. e.g. SOLID is guidance, to be taken under consideration, applicable in some scenarios and not in others, it is not the word of god / the one true way. Developers spend too much time fighting over their interpretation of what is basically other people's opinions, something they have read very recently in a blog or seen in a course, as if it is some sort of divine inspiration. They then point-score as to who has the most perfect understanding of the opinion of someone who wrote a book about their own experience, but has no idea of the realities of the project you are now working on. I have been in so many code reviews, where developers were obsessed with arguing over the minutiae of a particular line of code and how it does not meet framework guidelines / latest C# language syntax / a specific pattern in a book, that they completely missed that it did not actually meet the business requirements. Guidance such as SOLID, Clean Coding, DDD etc. is fine if you treat it in the same way as 'look both ways before crossing the road', but not 'you must spend 10 seconds when looking left, and no more than 1 second later, look right for 13 seconds, or a successful crossing of the road will be deemed inadmissible' Be pragmatic instead of dogmatic, is the best advice I can give, after 32 years of building systems.
