Step | Description |
1 | Integration Server makes the final retry attempt and the MQTT trigger service fails because of an ISRuntimeException. |
2 | Integration Server treats the last trigger service failure as a ServiceException. |
3 | If the acknowledgement mode is Client Acknowledgment, Integration Server acknowledges the message to the MQTT server. If the message is persisted, the MQTT server deletes the message. Note: If the message was not persisted, the MQTT server will have deleted the message for the trigger subscription already. |
4 | Integration Server processes the next message in the local trigger queue for the MQTT trigger. |
