Delaying Messages

In case of Ecotone we don't delay whole Message, but specific Message Handler. This helps in scenarios when we have multiple Event Handler and we would like to configure the delay differently. For example may we have a case, where as a result of Order being placed, we would want to delay notification, yet to call Payment Service right away.

Static Delay

You may delay handling given asynchronous message by adding #[Delayed] attribute.

#[Delayed(new TimeSpan(seconds: 50))]
#[Asynchronous("notifications")]
#[EventHandler(endpointId: "welcomeEmail")]
public function sendWelcomeNotificationlWhen(UserWasRegistered $event): void
{
   // handle welcome notification
}

The delay is defined in milliseconds.

Dynamic Delay

We may send an Message and tell Ecotone to delay it using deliveryDelay Message Header:

$commandBus->sendWithRouting(
    "askForOrderReview", 
    "userId", 
    metadata: ["deliveryDelay" => new TimeSpan(days: 1)]
);

Asynchronous Message Channel need to support this option to be used
