Package akka.javasdk.keyvalueentity

package akka.javasdk.keyvalueentity

Key Value Entity components for building stateful services that persist complete state on every change.

Key Value Entities are stateful components that store their entire state with each update, unlike Event Sourced Entities which store a sequence of events. This makes them suitable for use cases where you need simple state management without event history.

The main classes in this package are:

• KeyValueEntity - The base class for implementing Key Value Entities
• CommandContext - Context available during command processing
• KeyValueEntityContext - Context available during entity construction
