public static interface EventSourcedEntity.Effect<T>

An Effect describes the actions that the Akka runtime should perform after a command handler completes. Effects are declarative instructions that tell the runtime how to persist events, send replies, or handle errors.

Event Sourced Entity effects can:

• Persist events and send a reply to the caller
• Reply directly to the caller without persisting events
• Return an error message to reject the command
• Delete the entity after persisting a final event
