Utility Session Management - It's Inside the Database in Teradata 13.10! (UPDATED) - comment by carrie

TPT Stream will not use a utility slot.  TPT Stream operator and it's predecessor, TPump, use SQL-based load approaches and therefore do not tie up resources to the degree that TPT Load (FastLoad) or TPT Update (MultiLoad) do.  That is why TPT Stream jobs are unlimited.
