Usage of Join indexes? - response (6) by M.Saeed Khurram

Nishant,
I believe within Teradata you have a universe of optimizations. There are plenty of ways avaialble to optimize BTEQ for loading purposes.
You can start optimizations from your SQL SELECT within BTEQ, make the use of exlain and optmize the joins as much as you can, you can use drived tables and volatile tables in order to avoid lot of spool files, one you SELECT is efficient you BTEQ will improve much. Other considrations can be to choose you indexes to make the insert efficient and avoid Secondary Indexes on the target table before loading.
