Subject [jira] [Commented] (HIVE-11468) Vectorize: Struct IN() clauses
Date Thu, 06 Aug 2015 03:34:07 GMT

    [ https://issues.apache.org/jira/browse/HIVE-11468?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14659425#comment-14659425
] 

Matt McCline commented on HIVE-11468:
-------------------------------------

Patch 2 adds more tests and verifies integers, strings, and doubles (probably never will be
used) will vectorize in Vectorized Struct IN().  No decimal, timestamp, date for now.

Note the semantic type checking for struct constants is extremely inflexible.  Types must
be exact, so you'll see capital L being added in the struct expressions to make integers type
bigint, or the query will not parse...
