Query on Durable Subscriptions Support|OPC UA Implementation: Stacks, Tools, and Samples|Forum|OPC Foundation

Hello,

Do we have any Sample Server which implements Durable Subscriptions?

https://reference.opcfoundatio.....4/docs/6.8

We have a use case, where Devices run the OPC UA Servers. We have a Centralized Database Application which stores data from 1000s of controllers.

Existing protocols have specific ways to tell the Server to start sending data at a specific time.

For intermediate network losses, OPC UA Republish works but for long-term time losses, we are exploring if any built-in logic of OPC UA can be used or if is it completely application-specific.

If it is application-specific, the application layer DOES NOT always have control of the internal OPC UA Queues managed by the SDK, so I was exploring if Durable Subscriptions is the solution but I see that not many SDKs have it available.
