# Distributed Message Reply

The `Distributed Message Reply` is responsible for sending a reply to a listener after receiving a request. Upon activation, the task constructs a reply message using the provided serviceName, id, and data, then sends it to the listener. It expects an immediate confirmation reply indicating that the message was successfully received.

| ------------- | --------- | -------- | -------- | ------------------------------- |

| Attempts   |  `Integer` |          |  100       |  Defines the number of times the task will attempt to send a message if the initial attempt fails |
| Sleep between attempts |  `Integer` |          |    5000      | Sets the time in milliseconds that the task will wait before making another attempt after a failure |

## Behavior

The tasks constructs a reply with the necessary data, and sends this reply back to the listener. It retries sending the message if the initial attempt fails, up to the defined number of attempts. The task expects an immediate confirmation upon sending the reply, and if it does not receive this confirmation within a specified timeout, it considers the operation failed.
