Subj:   Load time of utilities vs. data size
 
From:   Anomy Anom

Dear Gurus,

1. What are the ballpark load times of 10 GB or 100 GB of data from a text file into a table using Teradata utilities? (Like bteq, fastload, multiload, tpump.) Data size vs Load time: is the progression linear?

2. What are the different factors which slowdown the load activity? (One I think of is network if the source file is transported over network.)

3. What percentage of production data needs to be put in pre-production environment if there is one other than development and testing environments?


Regards

Anom.
