tapahtumavarastoihin
Tapahtumavarastoihin, or event sourcing, is an architectural pattern where all changes to application state are stored as a sequence of immutable events. Instead of updating data in place, each modification is recorded as a distinct event in an append-only log, the event store. This event log becomes the source of truth for the application's state.
To reconstruct the current state of an entity or the entire application, the system reads the sequence
Event sourcing offers several advantages. It provides a complete audit trail of all state changes, making debugging
However, event sourcing also introduces complexities. Managing the event store, handling schema evolution of events, and
