Which column should i select for Index creation - forum topic by quest

Hi All,
I have data in an csv file and I am planning to create an table in Teradata and insert these records.
I then need to create an PI after the analyzing the data properties.
I somehow need to know the queries for the following.
1) Get the data distribution among all the AMP's
2) How many AMP's are there in the current installation?
3) Other queries which will help me identifying the right Primary Index
 
Thanks for your response in advance.
