Annotation Type AppHAPolicy

@Retention(value=RUNTIME)
@Target(value=TYPE)
public @interface AppHAPolicy

Annotates the main application class to specifies it's AepEngine.HAPolicy.

A clustered Talon application must specify the AepEngine.HAPolicy. Annotating an application's main class will cause the talon server to configure the application's AepEngineDescriptor.setHAPolicy(com.neeve.aep.AepEngine.HAPolicy) with this value, just before injecting the AepEngineDescriptor via an AppInjectionPoint annotated method. Thus, if an application programmatically sets the AepEngine.HAPolicy in the AepEngineDescriptor via an AppInjectionPoint the programmatically set value will take precedence.

Example

This example below indicates that the application will use the EventSourcing HA Policy.

 @AppHAPolicy(HAPolicy.EventSourcing)
 public class DQPerfDriverApp {
 
   @EventHandler
   public void onCreateCustomer(CreateCustomerMessage message) {
     System.out.println("Received " + message.toJsonString());
   }
 }
