PubSub+ Event Broker

Question 1:
when will the non durable endpoint be removed in solace ??
==> When the client session is fully going down ?? received SessionEvent.SessionDown ???
==> In case the client session is recovered successfully through the reconnecting mechanism [ Receive SessionEvent.Reconnecting and SessionEvent.Reconnected]…
Then, the non durable endpoint would still exist at solace appliance ??

Question 2:
how can i add topics subscription to a non-durable queue ??
Is there any sample code in c# ??? Thanks.

A non-durable endpoint will be removed from solace 60 seconds after the client that created it disconnects from the broker. The 60 seconds allows the client to reconnect before the non-durable endpoint and its contents are deleted.

To add a subscription to a non-durable queue, that can be achieved through the client application.

session.Subscribe(queue, topicA, SubscribeFlag.WaitForConfirm, null);

Where queue is your non-durable queue, topicA is the topic you would like to add to your queue, and the optional flag confirms the subscription has been applied successfully to the queue.

is the “60 second” be configurable in solace ??
(by vpn level ?? or solace level ?? or client profile level??0

The 60 seconds is non-configurable, however a client application that has the correct permissions can de-provision an endpoint sooner if it is not needed.
