Remote tags subscription, case to manage or not in the module: failover, disconnection?

[mazeyrat]

I use subscribeAsync to subscribe to tag value change.

subscribeAsync - TagManager

My module run on a frontend redundant gateway and I subscribe remote tags on a backend redundant gateway.

Subscribe is done on gateway startup script and unsubscribe in the gateway shutdown script.

• I don't know if I need to manage something from my side in the module when there is a backend failover ?
  or Ignition subscribeAsync implementation manage automatically subscription on the new active node ?

• I don't know if I need to manage something from my side in the module if when I subscribe the backend gateways are not connected to the frontend ?
  or Ignition subscribeAsync implementation automatically notify resend the request when the node is again available ?

A question probably for @mgross !
