Event sourcing

Meaning in software engineering, with examples

nounAdvanced term

In software engineering, event sourcing means: Keeping a sequence of domain events as the authoritative record and deriving application state from those events.

In Turkish: olay kaynaklı durum saklama

How it is used

Used when history and reconstruction matter. Merely publishing events does not make a system event-sourced.

Example sentences

  1. With event sourcing, the account balance is rebuilt from the recorded credit and debit events.

    The event history, rather than only the latest balance, is the authoritative record.

  2. We replayed the history from event sourcing to build a new reporting projection.

    The same stored events can produce a new read model without repeating real-world actions.

Common collocations

  • adopt event sourcing
  • event sourcing architecture
  • event-driven architectureA software design style where components communicate by producing and reacting to events instead of direct, tightly coupled calls.
  • stateThe data an app or component holds at a given moment, such as whether a menu is open or what a user has typed, which controls what is shown.
