Event sourcing is a design pattern that focuses on persisting the full history of a domain as a sequence of events rather than just storing the current state. This approach allows for a more comprehensive understanding of changes within an application, as each event represents a change in state, making it easier to debug and audit the application logic ⁵.

There are several key benefits associated with event sourcing. It provides a complete audit trail, enabling developers to replay events to reconstruct the application’s state at any point in time. This can significantly enhance debugging capabilities and allow for easier tracking of changes ⁴. Additionally, event sourcing can improve application performance by eliminating the need for concurrent updates and allowing for gradual state changes ⁴.

However, it’s important to note that event sourcing may not be suitable for all applications. It is particularly beneficial in complex and ever-changing domains, but may not be necessary for simpler enterprise applications ⁵. The implementation of event sourcing should be pragmatic, taking into account the specific context and requirements of the system being developed ¹.
