Difference Between Multiload And Tpump? |
|
Answer» Tpump provides an alternative to MULTILOAD for low volume batch maintenance of large databases under control of a Teradata system. Tpump updates information in real time, acquiring every bit of a data from the client system with low processor utilization. It does this through a continuous feed of data into the data warehouse, rather than the TRADITIONAL batch updates. Continuous updates RESULTS in more accurate, TIMELY data. Tpump uses row hash locks than table LEVEL locks. This allows you to run queries while Tpump is running.
