To me that situation seems like it should be modeled as a queue.
Fair point, however ...
I think it would be very worthwhile in this discussion to figure out at
what point we feel that a customer ought to opt for a queue rather than
a message group.
... I think one of the criteria is how many groups there are and how
dynamic the set of groups is.
In this example it might be that there are lots and lots of objects, but
only a few processing 'engines'. Further, the exact set of objects might
be dynamic. I don't want to have to tie the processing engines to
specific queues for each object, I want them to adapt to the changing
system.
