WebJun 4, 2024 · In order to make Event Sourcing work, you have to do a few extra things over and above just logging the events such as maintaining the order, snapshotting etc as well as creating the logic which reads in the event log and creates the object state. In my opinion Event Sourcing never really took off. WebJun 11, 2024 · In my opinion, Event Sourcing is not required when we implement CQRS. Yet, the opposite it not necessarily true. Indeed, for most of the use cases, CQRS is required when we implement Event Sourcing because we may want to retrieve a state in O(1) without having to compute n different events. One exception is the use case of a simple audit log. should you go first albert rowswell

WebEvent sourcing and CQRS are useful approaches for understanding the tradeoffs of event storage. But event sourcing is actually a subset of event streaming, since it only concerns a single app or microservice with a single storage model, along with a single database featuring data at rest. Event streaming adds connectivity to event sourcing ...

In this tutorial, we'll explore the basic concepts of Command Query Responsibility Segregation (CQRS) and Event Sourcing design patterns. While often cited as complementary patterns, we'll try to understand them separately and finally see how they complement each other.
