Nice concise introduction to #CQRS and #EventSourcing with - The Dynamic Duo: Event Sourcing and CQRS by Marat Miftakhov learncqrs.com/8HoqGv?list=ar…

David Boyne 🚀 Marvel Snap uses CQRS, event sourcing, recomposing on client. Only within a 1v1 game session, and pinned to a version. We avoided schema versioning problems that way. IME it's great for short lived uses or archival-only, difficult if long lived + you plan to interpret the events.

Bringing idempotency to a distributed reactive system is a considerable challenge. What do I mean by idempotency treatment? Absolutely is not a message HASH or GUID control. Modeling Uncertainty is the more efficient way to deal with this... #DDDesign

Great read from the engineering team at @AutoTraderLife: Real-Time Personalisation of Search Results with Auto Trader's Customer Data Platform Broadcasting user behaviour events. Derived data. API gateway. Lots of goodness. learncqrs.com/wp2dCa?list=ar…

In this article, I explore what ACK/NACK protocol messages are and how they can be used with #CQRS. acairns.substack.com/p/acknack-for-…

Making your Application Stable with the Outbox Pattern. In this article Dariusz Gafka discusses the advantages of the Outbox pattern and why you want to persist your events at the same time as other state changes. learncqrs.com/vY7A3z

An ACK/NACK strategy for Commands when applying #CQRS by Andrew Cairns learncqrs.com/1HkVSB

Shitting on SOLID has become too popular. Which principle are you so against and why? Do you like objects w/ many responsibilities and reasons to change? Modifying stable code to add functionality? Perhaps you love large interfaces? Or new'ing within your classes? You do you.

"Architecture is the translation of strategy into technology." — Dana Bredemeyer

"Events are our primary mechanism for achieving consistency outside of consistency boundaries." - Nick Chamberlain learncqrs.com/dPnLxw

Working with a legacy system presented some challenges with transaction boundaries. Be mindful of consumers with side-effects. More in my devlog: youtu.be/y67hTtS37yw

This guy is gonna be talking about #DDDesign and #CQRS soon. Maybe even a little #EventSourcing! youtube.com/@andrew.cairns

Wrote an integration test, got 3 people educating me why unit tests shouldn't touch the database. How is your day going?

Fascinating talk by Udi Dahan at @ndc_conferences: "CQRS pitfalls and patterns" - particularly interesting perspective on Public/Private Responsibility Segregation. learncqrs.com/bOi45N

Understanding CAP Theorem is important when designing distributed systems. CQRS can avoid the limitations of CAP Theorem by splitting Reads (optimised for Availability) and Writes (optimised for Consistency) into different systems. youtube.com/shorts/DxywRiK…

Playing around with an idea to visually explain Partition Tolerance. Thinking about doing a more in-depth video about CAP Theorem, how it can be used as a design tool for distributed systems and how #CQRS relates.

Accidentally discovered some funky behaviour when running an artisan command - and I recommend you avoid using it!! 😅 youtube.com/watch?v=gCQRhX… #laravel #php

What can we learn about Software Development from Retro Games? As it turns out... quite a lot! Sharing a teaser for the upcoming video:

What is a Command Bus? If you haven't encountered a Command Bus before, or not quite clear on it's purpose - this might help you develop an easy way to think about them. youtu.be/pXVZhFE2pbk
