How LS server uses the deployed adapter(s)?

You get property3 in 3 cases out of 4. I assume it's a typo.

If only some field values change, unchanged field values are not resent to the client.
Hence, if unneeded fields don't change very much, leaving them in the subscription schema only adds a negligible overhead.

On the other hand, if unneeded fields change a lot, you may prefer the resubscription.
I can't understand what you mean by "I can add the conditional properties as items";
in my view, you could work with one item and use different subscription schemas, according with the needed fields.
