Subject [jira] [Commented] (HIVE-3072) Hive List Bucketing - DDL support
Date Mon, 11 Jun 2012 19:30:43 GMT


Carl Steinbach commented on HIVE-3072:

If this feature requires metastore changes then I'd like to request that the first patch contain
only changes to the metastore schema and metastore Thrift API. I would also prefer that the
DML and DDL changes go in as a single patch since it a) prevents half-implemented features
from showing up in releases and b) demonstrates that the feature actually works.

> 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.
