Subject [jira] [Commented] (HIVE-3072) Hive List Bucketing - DDL support
Date Mon, 11 Jun 2012 18:57:19 GMT


Gang Tim Liu commented on HIVE-3072:

making progress on DML. The following syntax started to work: 
        create table T (c1 string, c2 string) list bucketed by (c1) with skew ('x1');
        create table T (c1 string, c2 string, c3 string) list bucketed by (c1, c2) with skew
(('x1', 'x2'), ('y1', 'y2'));

> If a hive table column has skewed keys, query performance on non-skewed key is always
impacted. Hive List Bucketing feature will address it:
> This jira issue will track DDL change for the feature. It's for both single skewed column
and multiple columns.
