I don't understand what you are trying to do. "user_name=$name and
password=$pwd" will refresh only the user matching both parameters,
which theoretically is 0 or 1 user.

OK. So, even if a new query results in individual object cache to be
flushed, we are still avoiding DB hits becasue we have query result
cache in place.
Does query result cache gets individually flushed, or the only way
is group flush [1]? Actually, I want to cache User objects (or query
results) forever. User object is retrieved when user logs in using
an expression like "user_name=$name and password=$pwd". I want to
make sure that whenever a user updates his information the object
and query result for that particular user gets flushed, not all the
users that were retrieved using "user_name=$name and password=$pwd"
expression. Please suggest.

Yes, a query refreshes cached objects (unless the query itself is
served from cache).

Hi,
I am a bit confused on the way Cayenne handles object-cache. It
sounds to me that object-cache gets invalidated [1], whenever a
call like this takes place
loadMenu(){...
SelectQuery query = new SelectQuery(PaintingType.class, ...);
return (List<PaintingType>)context.performQuery(query);
}
Now, there are multiple users accessing the same page that calls
loadMenu(), as per the document [1], for each user Object-Cache for
this would be flushed and restores.
