Had an excellent week at the inaugural @eventcentric.bsky.social , and the wider @dddeu.bsky.social. Great to catch up with old friends, and meet some new ones. Thanks to everyone who came to watch me talk, it still blows my little mind that > 0 people are interested in hearing me talk on a stage.

Loved presenting at #EventCentric on @wixeng.bsky.social event-driven, domain-driven design: single-aggregate microservices with only public integration events. Boosts dev speed but posed ops challenges we solved. Slides in first comment. #DDD #EventDrivenArchitecture #IntegrationEvents

Last talk of @eventcentric.bsky.social by @jameseastham.co.uk telling us how we maintain a reliable event-driven systems 🎉

"Choreography is the collaboration between multiple orchestrators, across bounded contexts" I love watching @icooper.bsky.social talk, always so many quality takeaways and little snippets of knowledge. @eventcentric.bsky.social #eventcentric

Ian Cooper on stage talking about "Automating Business Processes" on stage at #EventCentric

This morning we kick off proceedings with a keynote from James Lewis (@thoughtworks.com) on 10 years of Microservices.

Oskar Dudycz is giving the day's closing keynote (in an excellent shirt) about Event-Driven Modelling Anti-Patterns #eventcentric

Right now Mihai Budiu is on stage talking about "Unifying databases and streaming systems" 🤝 #eventcentric

Lunch is underway at #eventcentric and @dddeu.bsky.social #dddeu!

I'll be speaking at EventCentric in Antwerp tomorrow and it's going to be... a lot. Expect discussions of CloudEvents and xRegistry and JSON Structure and Agents and Codegen and LLMs and data quality. #eventcentric 2025.eventcentric.eu/schedule/

Anita Kvamme now showing us the what, the why and the how of event sourcing. Including the good parts and the hard parts. 🎉 #eventcentric @eventcentric.bsky.social

@noctovis.bsky.social up next bringing the love for orchestration and choreography at @eventcentric.bsky.social #eventcentric

Hanging out at the @akka.io booth at @eventcentric.bsky.social and people recognize me, which is scary. Me: "I didn't do it! How did you find me?!" Then I discover people know me as "that #Rust guy" or "that @wasmcloud.com guy". Then I get to chat about #EventSourcing, which is nice.

And...we're underway with the first edition of EventCentric! Sheen Brisals giving the keynote.

At @eventcentric.bsky.social , ready to get my eventing on! We don't get to see the sessions in real-time, we just watch their event logs as events come in #EventSourcing

On my way to @eventcentric.bsky.social

Heading to @eventcentric.bsky.social for two days of great talks, looking forward to talk with @noctovis.bsky.social about event versioning and @oskardudycz.bsky.social about Event Sourcing 😊

Join this session to explore how the durable execution programming model makes building distributed systems with CQRS and Event Sourcing easy and effective! buff.ly/4bfVpD6 Check out the full program buff.ly/4bfVpD6 #eventsourcing #cqrs #durableexecution

In the video, Jérémie Chassaing pulls apart the buzzwords and shows how a functional approach leads first to domain code that is easily readable and highly testable.

What happens if you mix #EventStorming with a Low Code Platform? Christof Heinzel & Alexander Miertsch will take you on a visual modelling journey based on a real use case from a client's project.

Join Natan Silnitsky, Backend Infrastructure Tech Lead at Wix for his talk on "Redefining Event-Driven Architecture at Wix - Integration Ignited" This will be a must-watch! 2025.eventcentric.eu/program/rede...

With the rise in momentum and adoption of CQRS and Event Sourcing, so has the importance of projections. Yet, there's not much on the role they play. We'll look at the various ways to go about designing, authoring, and testing projections.

In this talk, Ian Cooper will deep dive into the analysis, design and execution of business processes. Along the way, we will cover thorny topics like orchestration, choreography, routing slips and sagas. See more info on our program - buff.ly/4bfVpD6 #orchestration #domainmodelling

Peter Royal will uncover the design and implementation of an application helping power Netflix’s studio. Borrowing ideas from #EventSourcing and #CQRS, he will show how this model is aligned with modern cloud-based architectures and capabilities desired in business applications.

Building an event-driven system is hard, but evolving, and therefore versioning it is even harder! Join Laila Bougria @noctovis in this session where she discusses versioning strategies to help you evolve your EDAs. Learn more - buff.ly/4bfVpD6

A quick trip to Antwerp and a final venue visit for @dddeu.bsky.social , @eventcentric.bsky.social & @datameshlive.bsky.social . This month my calendar (and head) are packed but I'm not complaining ;)

Traceability, Consistency, Correctness. Why Nordic fintech Lunar chose #eventsourcing and the challenges it brought.

Based on interviews with 25 engineers, in which 19 event-sourced systems are discussed, Michael Overeem, lead software architect at AFAS explores the rationale for event-sourcing.

You have a little over 24 hours untill our early-bird ends! This is the final opportunity to get a discounted rate on our ticket. EventCentric is the coming together of the community of builders of event-driven systems. Don't wait!

In this talk, Sheen will explain how enterprises should decompose by starting at the organizational level, applying Domain-Driven Design, and distilling to a level where teams can operate within a boundary, ownership, and autonomy. More information -

There are patterns for dealing with conflicting updates in traditional data stores but how do you deal with conflicts when you have event streams? This video covers patterns for conflict detection in traditional storage and how event-sourced systems differ when conflicts occur.

An EventSourcing experience report: Lessons on event synchronization in mostly-offline settings, and conflict management.

It’s only 7 days before our early-bird pricing ends. Buy your ticket today! Join other engineers and architects building event-driven systems. Talks on durable execution, versioning, event sourcing, streaming and much more.

A team had a dream: to make their organisation rethink their relationship with data. But they faced some challanges: legacy, other teams, and proprietary systems. Welcome to Eurostar journey into building a middleware event-sourcing platform More information - eventcentric.eu/program

Most systems will have to deal with future or deferred events. Even the most common example of software on the web — a blog — will have the ability to “publish” a post in the future at a certain time.

Early-bird pricing for EventCentric ends on April 30. Purchase your tickets for your team before then! EventCentric will be the in-person meeting point for developers and architects building event-driven systems, interested in learning the best practices and tools to help their teams.

This is a case study about how Lunar Bank prepared for hyper-growth with an event-driven architecture and DDD as its foundation. Key insight: Tech excellence (event sourcing) + organizational structure (domains and squads) must work in tandem to scale a modern digital bank.

There are things that you usually learn too late. In Event-Driven systems such thing is the criticality of event modelling. Oskar will share anti-patterns he learned too late so you could avoid them! buff.ly/4bfVpD6

Event-sourced applications can leverage pure functions without the need for framework-specific code in your model. Occurrent, an OSS event sourcing library for the JVM, provides an easy way to store your domain events in compliance with the CloudEvent specification.

This video will explore architectures which have emerged based on event logs, what they are useful for, and the consequences of different approaches. The focus will be on attributes such as fault tolerance, scalability, operations, integration, and development concerns.

Secure your seat at EventCentric before April 30 to benefit from our early-bird pricing.

The key to unifying databases and streaming systems is incremental computation. In this talk by Mihai Budiu, he'll explain the why and how. eventcentric.eu/program

Michiel Overeem is a Lead Software Architect at AFAS. In this video he will describe the journey of the past 11 years: how do they apply #eventsourcing, what they learned, and what they changed.
