Subj:   Teradata Columnar distribution and retrieval
 
From:   Sughesh.Sumansingh

Hi Experts,

I have read manual explaining Teradata columnar, but I am not clear about below point.

1. While retrieving data, how it retrieve columns from different partitions and project it as row (if I am using Select * or column list from table) ?

It is mentioned that it will take more CPU to glue columns to project as a row.


Thank you.


Regards,

Sughesh.
