I read a microsoft white paper that explain 1TB data loading in 30 minutes with SSIS.
"We Loaded 1TB in 30 Minutes with SSIS, and So Can You"
In this paper, the source is multiple text files. Most of the cases we need to load data from a single table and selecting data (filter the data for parallel load) from a single table would be very expensive.
My question here is, what are the methods to do a parallel load if the source is single table?
