Example: Creating User with Permanent Space Skew Limit - Teradata Vantage - Analytics Database

On a system with 4 AMPs, you create a user with 1 gigabyte of permanent space. The per-AMP quota of permanent space is 250 megabytes. If you set the permanent space skew limit to 10%, any AMP is allowed a skew limit of 25 megabytes over the per-AMP quota of permanent space. An AMP can use up to 275 megabytes of permanent space as long as total permanent space used does not exceed the 1 gigabyte global limit for permanent space.

CREATE USER user1 AS
  PASSWORD = (EXPIRE = 0), 
  PERM = 1e9 SKEW = 10 PERCENT;
