Every time you mention GFS, you're really talking about Bigtable (which happens to be built on top of GFS)
It is all in 1000 buckets. Ever gone beyond page 100 in google results? You can't. Even though there are millions of results you can only get to page 99 at 10 results per page because it too is built on GFS.
> Sorry, Google does not serve more than 1000 results for any query. (You asked for results starting from 1000.)
