set_fields_of_interest
Description:
Client can instruct server to which fields it is interested in only, thus the server can return less data over the wire.
The server can still return complete objects, this is just a hint to it that the listed fields will be used only. The UID/RID fields are
returned always. Initial views has no fields of interest and using null for fields_of_interest
will unset any previous changes.
Some backends can use summary information of its cache to create artifical objects, which will omit stored object parsing. If this cannot be done then it will simply return object as is stored in the cache.
Parameters:
