What is KurrentDB?
KurrentDB is an event-native database designed specifically to store, process, and deliver application state changes, known as events.
Each event captures a specific change in the state. Examples include when an order is placed, a payment is processed, or an item is shipped. By capturing all these incremental updates, KurrentDB captures temporal context and provides a complete audit trail of a business process.
KurrentDB offers the following features:
