There's more...

With skew comes many performance issues, be it on space or at the query level. The following process flowchart will help you to reduce the skew and improve database performance:

One more thing you can check is the amount of space you have wasted due to skew in the database. The skew formula, as seen previously, can be modified to get it. This will help you identify how efficiently you have utilized the space allocated to you. Every byte of space is important when you are on a space constraint system. It also reduces overall system skewness:

/**Waste space query**/
Lock dbc.tablesize for Access
select TableName, sum(CurrentPerm) as ActualSpace,count(*)*(max(CurrentPerm)-avg(CurrentPerm)) as WastedSpace
 from dbc.TableSize where DatabaseName=<my_database> group by TableName order by WastedSpace desc;

Shared nothing architecture makes Teradata efficient and creates a parallel efficient system and we should make the best of it.
