Teradata TPUMP stage

·        TPump is a highly parallel utility designed to continuously move data from data sources into Teradata.

·        TPump is typically used for loading a small quantity of records in relation to the size of your target table.

·        TPump works at the row level, whereas MultiLoad and FastLoad update whole blocks of data. TPump allowing us to load data into tables with referential integrity which MultiLoad doesn’t.

·        TPump only needs to take row-level locks; in other words, TPump only places a lock upon the row it is modifying. In contrast, MultiLoad places locks on the entire table. If you need multiple processes updating a table simultaneously, TPump may be the better solution.

·        TPump also uses fewer system resources, so you can run it concurrently with user queries without impacting system performance.

·        TPump lets you control the rate at which updates are applied. You can dynamically “throttle down” when the system is busy and throttle up when activity is lighter.

·        TPump does not take a utility slot.

·        TPump is designed for “trickle feed” taking individual row-level locks. If you use TPUMP, you need to make sure that you follow normal TPUMP standards (Set the KEY statements equal to the PI and turn SERIALIZE on).

·        Tpump is typically for processes that are constantly retrieving and processing data, like from a message queue.

·        Using TPump offers a controllable transition to updating that is closer to real time. Best fit in “Active”, “real-time” or “closed-loop” data warehousing.
