#eventsourcing — Public Fediverse posts

Reminder that tonight I'm speaking in Hamburg (at the Microservices Meetup) about #EventSourcing! I know it's short-notice, but if you're around, come on by and let me share with you my passion on the topic! https://www.meetup.com/microservices-meetup-hamburg/events/316350578/

CQRS, async with retries and dead-lettering, event sourcing, projections, workflows. That feature list usually means a platform team.

I built it as an e-commerce shop on Tempest + Ecotone. The entire messaging layer: about a dozen small classes of business logic. No worker command, no repository, no queue wiring.

The Order aggregate IS the Tempest database model. One class, both frameworks.

My WIP Ruby stack

I have been iterating on Event Sourcing and CQRS architectures for nearly a decade. When I first started with this pattern around 2016 and 2017, the implementation was considerably more complex. Over the years I have stripped it back again and again, and what I have arrived at now is something I'm genuinely happy with: a small, focused TypeScript library backed by DynamoDB that does exactly what it needs to and nothing more: https://coderbyheart.com/es-and-cqrs-on-aws-simplified #eventsourcing #cqrs #aws

Your customer received €50. The notification on their phone says "New balance: €100." Should be €150 — the notification queried the read model before the projection committed.

That race lives in most CQRS systems. Wrote up how to close it for good in PHP — by emitting derived events from inside the projection.

Next week I will speak at BASTA! Conference in Frankfurt, about #SoftwareArchitecture, #CSharp, #LLM use in #CQRS and #EventSourcing systems, and much else. 🌎 Bring your thinking hat for my #BASTAllionaire game show 🎉! Say hello if you see me, or come talk about #DevExpress. 🚀 https://basta.net/frankfurt/

I've developed #Ecotone Framework based on the principle that we should fully focus on business features, not the technical infrastructure part.

However, in some cases where optimization of requests is critical, auto-initialization may come with a performance penalty.

For this #Ecotone provides now migrations, that can help optimize this process:

I broke down Event Sourcing in Quarkus using Java records, sealed types, pure functions, and a clean CQRS split.

Fully hands-on. No magic. Just data, folds, and clear architecture.
If you want to understand event sourcing without the hype, this one is for you.
