Re: [Opensymphony-oscache] groups usage for a newbie

if an object only belongs to one parent group, you should not have any 
duplicated data.  Of course, if it does, you would have a duplicate for 
each group.

another possibility is if these relationships are represented in the db 
and you are using hibernate then when you query for objects of a 
particular group the results could be stored in the query cache.  the 
results being just a list of ids.  the objects themselves would be 
stored by their pk.
