Event Sourcing and CQRS are possibly the most fascinating architectural patterns in the software world, especially when combined with an event-driven architecture (EDA). In contrast to traditional applications that store exclusively the current state of the system while losing the history of all operations and changes applied to it, event sourcing dictates that all state changes have to be represented as events and persisted an append-event only log. The state of the system is sourced from such events through a process called hydration.
Auditing and the ability of replay the history of events to hydrate new versions of our model are some of the incredible benefits this patterns give us. However, the challenges are equivalently important.
In this video, we will try to reach a conclusion and establish whether we should these patterns use in our system.
A lot of inspiration has been taken by articles and presentations by Greg Young and Martin Fowler.
