When migrating logic from SSL to RSSL (using UPA/ETA), there is logic in the SSL application that will detect when either a group or an item has become "STALE". These are delivered when SSL_(ITEM|GROUP)_STATUS_TYPE is set to SSL_ET_(ITEM|GROUP)_STATUS_STATLE.
Looking at the logs in the application and correlating them with the EED, it appears that this event is sent to the application when the EED loses its upstream connection -- possibly indicating that there could be a gap in the data.
I can't find a way to receive similar notifications in ETA (or UPA).
Does such a notification event exist?
If not, how can the downstream application be notified that there may be a possible gap in the data?
