Born to be Parallel. Only he who attempts the Ridiculous may achieve the impossible. Don Qulxote

The concept of parallel processing back in 1979 was almost an outrageous as attempting to go to the moon, but Teradata attempted the ridiculous and the impossible was achieved. Teradata took every table and spread the rows across all the AMPs in the system and the birth of parallel processing happened.

You will never see a Teradata table that is only on one AMP. the parallel processing aspect is then lost. you will see every Teradata table spread the rows of the table across all AMPs. Teradata was born to be parallel and the impossible was born.

The first picture on the opposite page never happens. The second Picture below that is exactly the design behind Teradata.
