I would like to suggest a new option or extension to update statistics where
update statistics could start up in a table where it left off the last time
it was run, like the "reorg rebuild, resume" command. Or be able to provide
a starting point in a clustered index. We have many tables where the data is
always being added to the end of table. It seems like a big waste of time
and I/O to process 50 million rows when all the new data is at the end of
the clustered index and the user or the system could identify the starting
point.

Example:

update statistics table, resume

or

update statistics table where date_created > '01jan03'

Assumming date_created is part of the clustered index
