what reasonable query compared tables unequivocally infinite datasets?


in stack podcast no. 19, joe news fogcreek's preference have one database per client instead one database clients. kinda sets me pondering following.

  3. each fan 1000 products.



so means i'm gonna have 1000 x 100 x 1000 = 100,000,000 products compared users. i join tables query user client's products, should reasonable volume query i only unparalleled database purpose?



update



maybe i wasn't pristine adequate question. assume i need sorts musty queries (min, max, group, etc.) datasets news above, delayed (or not) indicate creates improved clarity have churned database plan eg. 1 db/client, database sharding, etc.
