Change Data Capture turns DB row changes into real-time events, so your microservices stay in sync without dual writes or stale caches.

Embrace CDC for reliable event-driven data flow.

Event-Driven архитектура на FastAPI: через паттерн Pub/Sub

В мире разработки программного обеспечения постоянно появляются новые подходы к построению систем. Event-Driven архитектура выступает одним из наиболее перспективных решений для создания гибких и масштабируемых приложений. В данной статье мы расскажем о реализации Event-Driven архитектуры (EDA) с использованием FastAPI и паттерна Publish/Subscribe. Рассмотрим основные концепции, компоненты и практические примеры кода для создания масштабируемой системы обмена сообщениями.

Как я построил serverless OCR-сервис на AWS Lambda и Amazon Bedrock

В этом посте я расскажу, как на практике за пару часов реализовал serverless OCR-сервис на AWS, используя AWS Lambda и модель из Amazon Bedrock . Статья ориентирована на опытных AWS-архитекторов, поэтому мы углубимся в архитектуру, покажу код (Terraform для инфраструктуры и Python для Lambda), обсудим масштабирование, ограничения и прикинем стоимость решения в регионе eu-central-1 (Франкфурт) .

Past week I had the opportunity to write about the difference between Domain Events and Change Data Capture patterns.

Nowadays I'm very much involved in the implementation of these patterns and I wanted to share my learnings on that.

As Senior Software Engineers and Tech Leads we have to learn common patterns to solve problems in the most simple way and avoiding “reinvent the wheel”.

I want to thank Raul Junco for giving me the space on his newsletter and reaching his audience for this.

The Application Service is your transactional boundary. It defines the atomic scope of a use case, ensuring all related changes happen together, or not at all.

Decoupling matters. Even if you are using Domain-Driven Design, Event-Sourcing and Event-Driven, they should be loosely coupled. A change in your event publishing strategy should not require changes to your domain model. #DDD #EventSourcing #EventDriven

Event-Driven architecture helps with communication. It is about propagating changes and maintain systems decoupled each other. Not about persistence.

Event-Sourcing is a persistence mechanism. It changes how you store and load the state, but it should not leak outside the repository or be coupled with other parts of your code. #DDD #EventSourcing #EventDriven

Domain-Driven Design helps to better picture the business domain into your code. Particularly when things starts to grow.

Start simple: There is no need to start your system with #DDD, #EventSourcing or #EventDriven. Consider to let the system grow as the needs become clear.

Sharing this from my job (not on Mastodon). If you're into #eventdriven systems, #eventsourcing, #ddd, or anything like that, you should come hang out. It's pretty cool.

AxonIQ Conference 2025 is open for real-world talks — the messy, hard-won lessons from scaling with Axon, Event Sourcing, CQRS, and building systems that actually move business forward.

You survived. You leveled up.

🚀 Had a blast giving my talk on Wix Engineering's Kafka based async patterns at Devoxx Greece. Thank you for your insightful questions and discussions on why Wix doesn't have distributed transactions, Sagas and doesn't use the outbox pattern.

Just published an article inspired by the book club sessions with @matteopierro and @pietrodibello 📚

I shared some of my reflections on #DDD, #EventSourcing, and #EventDriven architecture. How your system can grow towards that direction, and how things can be well decoupled each other.

I am always curious to hear what's your take! What's your approach in your codebase? What trade-offs have you faced?
