Pragmatic Event Sourcing

Better Programming

Event sourcing is an architectural pattern; it’s not a silver bullet Continue reading on Better Programming

Event Sourcing: The new silver bullet?

Level Up Coding

Event Sourcing is part of a large architectural design called event-driven architecture. Here is what I have learned after research, and… Continue reading on Level Up Coding

Event sourcing

Software Architecture with C plus plus

You can think of events as notifications that contain additional data for the notified services to process. There is, however, another way to think of them: a change of state. Think how easy it would ...

Event sourcing

Software Architecture with C plus plus

As introduced in Chapter 2 , Architectural Styles , event sourcing means that instead of always storing the whole state of your application, possibly dealing with conflicts during updates, you can jus...

Do you really need “Event Sourcing”?

Javarevisited

“Event sourcing refers to a collection of patterns based on the idea of persisting the full history of a domain as sequence of events rather than persisting just the current state” — by Udi DahanSpoil...

Developer-friendly event sourcing

Javarevisited

Event sourcing is about persisting events instead of just the current state. Event sourcing can be helpful for auditing purposes, and to analyze or rebuild previous system states for business analysis...

When to Use Event Sourcing

Better Programming

Suppose you’re asked to design the database of a webshop. Most likely, a traditional sequel database design will have a users, products, and orders table — representing the state of the system. Let’s…...

What (and Why) is Event Sourcing?

Level Up Coding

Event sourcing is a data persistence strategy often mentioned in domain-driven design (DDD) and CQRS. The concepts are independent but complement each other perfectly. But how does event sourcing…

A Simple Event Sourcing Implementation in .NET

Level Up Coding

Event Sourcing is an extremely powerful Software Architecture concept, but it can certainly get very complicated! When people think Event Sourcing, they normally think it involves complex distributed ...

Event Sourcing with CQRS

Level Up Coding

Keith Redmond, VP of SaaS Engineering at Zartis, shares his insights on how to utilize Event Sourcing with CQRS in your application development. This article was presented as a webinar as part of the…...

Event Sourcing and CQRS: Key Techniques for Scalable Systems

Javarevisited

In our fast-paced digital world, some use cases require scalable and maintainable applications that can handle high amounts of traffic, load, and rapidly changing requirements. Event Sourcing and Comm...

Events: More Than Meets the Eye

Python in Plain English

A Deep Dive into Event Types for Web Service Development. When someone says an event, what do you think they mean? Domain Events? System Events? State Events? They might be talking about different th...

Event Driven Architecture Pattern

Towards Data Science

This is the most common distributed asynchronous architecture used to develop highly scalable system. The architecture consists of single-purpose event processing components that listen on events and…...

Exploring event-based architecture

Software Architecture with C plus plus

Event-based systems are those whose architecture revolves around processing events. There are components that generate events, the channels through which the events propagate, and the listeners who re...

CQRS & Event Sourcing III: the framework

Javarevisited

Let’s see the workings of the application in particular the Event Store and the Event Bus.This implementation is done in Kotlin but the same design could be rewritten with various languages. Full code...

Common event-based topologies

Software Architecture with C plus plus

The two main topologies of event-driven architectures are broker-based and mediator-based. Those topologies differ in how the events flow through the system. The mediator topology is best used when pr...

Commands in an Event-Driven Architecture

Better Programming

When we think of event-driven architecture (EDA), we naturally think of fire-and-forget events. But what happens when we need a response? Continue reading on Better Programming

Unleashing the Power of Event Storming

Javarevisited

After introducing what benefit can be brought into the system in my last article. I decided to build a Proof of Concept (POC) project with Event Sourcing and CQRS architecture. The first thing is to c...
