Example: Creating User with Temporary Space Skew Limit - Advanced SQL Engine - Teradata Database

For a system with 4 AMPs, you create a user with 1 gigabyte of temporary space. The per-AMP quota of temporary space is 250 megabytes. If you set the temporary skew limit to 20%, any AMP is allowed a skew limit of 50MB above the per-AMP quota of temporary space. An AMP can use up to 300 megabytes of temporary space as long as total temporary space used does not exceed the 1 gigabyte global limit for temporary space.

    CREATE USER user1 AS
    PASSWORD = (EXPIRE = 0),
    PERM = 1e9,
    TEMPORARY = 1e9 SKEW = 20 PERCENT;
