Client implementation to monitor 1000 variables on a server #6509

I am working on a client implementation where I need to subscribe to 1000 variables from a server. Right now, I am creating one subscription and adding the monitored variables using UA_Client_MonitoredItems_createDataChange() to the same subscription. Also, I am handling all the datachange callbacks through the same callback mechanism.

Is this approach good or should I create multiple subscriptions and add monitor items to them accordingly?

Using just one subscription is preferred.
If you want to receive all notifications together..

I guess this is not a critical issue then.

Thank you for your reply. This was an important design choice for us, hence I had marked it critical.
