Hi Dejan,

Indeed the concept of "clear snapshot" was introduced recently in our Adapters Interface and allows the Data Provider to force, for a given Item, the cleaning of the snapshot maintained by the server (clearSnapshot).
But this feature assumes that the items has yet subscribed and nothing can do in case the Item was unsubscribed (no more clients have active subscription for it). And this is why I think it is not useful in your case.

I confirm you that we are already considering the possibility of extending the Adapters interface in order to add the feature you suggest but unfortunately I can not provide a definite schedule for its introduction.

Thank you for your valuable tips.
Giuseppe
