Either Set or bag could be faster, depending upon the situation. Neither
require an <index> column. Hibernate bags are actually java.util.Lists
because the java collections framework has no Bag.

I have a collection of thing. I do not care whether
there is duplication or not. I can use Set to prohibit
duplication. I can also use list and bag.
If I use Set rather than list/bag, I think the
performance is not so good as it is for list/bag,
since set has to limit duplication.
I noticed that <index> tag is required for list. But
if I used linked list, I do not care about index. Can
I omit the <index> tag?
Therefore I think bag is a good choice for my
implementation: no index tag requirement and no
performance penalty from set. However where the bag is
declared? I looked through java.util.*. I did not find
it.
Thanks
jason
