Hi,
Our biggest problem here is that the IDBroker can only generate Integer
values. The same applies for sequences or auto increment primary keys.
If you want Turbine or your RDBMS to generate unique id's for you, you'll
probably find it easiest to go with a unique ID primary key. IMO it is
anyway a good design decision to use unique ID's.
We could document the fact that by default Peers use unique id Primary keys.
This should work for about 99.9% of the time. For all other cases people
are free to access the raw database, or to edit generate Peer classes by
hand for their specific needs.
It is not as if Peers will force you to use unique id primary keys. You'll
just have to do the work yourself if you want to do otherwise.
just my 2c
