We are trying to run a warehouse ETL using SSIS. Everytime we try we keep running out of harddisk space. When we ask for more space usually in the amount of 30 gigs and rerun we quickly eat that space up. That makes no sense. We are not importing 30 gig of data. A couple million records maybe and even then the lion share of those records are just getting merged with existing records (ie. maybe a few hundered additions to fact tables but most dim tables aren't touched).
When SSIS runs what is it that is taking up all the space? Is it log files? How can we keep our DB from growing out of control? Not sure if this belongs here or in the SSIS section. Admins feel free to move.
