TPUMP is a flexible multi-session load utility. The only characteristic of TPUMP that limits its use is its transaction oriented nature. If the situation allows execution of Fastload or Multiload, these utilities will always outperform TPUMP in a large batch operation when measuring Teradata resource consumption and response time. Consideration of TPUMP in a load scenario should occur before that of Fastload or Multiload. Basically TPUMP has none of the disadvantages of Multiload (table locking, load slot usage, single amp operations), Fastload (empty table only, load slot usage), or BTEQ (no checkpointing or restartability)
