Assume a system with 4 AMPs and 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.
     MODIFY USER user1 AS 
       PASSWORD = (EXPIRE = 0),
       PERM = 1e9 SKEW = 10 PERCENT;
