| Summary | 0003919: Clarification for durable subscription handling | ||||
| Description | A durable subscription queues values and events of monitored items in large, long living and persistent queues. After a client reconnects to a server and transfers a durable subscription to the new session, the server delivers the entries in the queues in the order the got queued to the client. This typically requires several Publish responses. There is currently no mechanism to tell the client that the stored values for a monitored item are delivered and the client has received the 'current' value. This is probably no problem if the received values are stored on the client side in a historian. But for the display of the 'current' value in a user interface, it would be important to know that the 'current' value was already delivered. | ||||

Change this to a feature request for durable subscription diagnostics used to provide information about the capability of the server to deliver all values back to the client in the case of a reconnect. Especially the situation where the server is constantly busy with delivering old values and is not able to deliver the new ones in time needs to be detected. |
