Subject [jira] [Commented] (HIVE-4844) Add varchar data type
Date Mon, 09 Sep 2013 16:35:52 GMT

    [ https://issues.apache.org/jira/browse/HIVE-4844?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13762007#comment-13762007

Xuefu Zhang commented on HIVE-4844:
-----------------------------------

I think people use varchar in Hive probably because of legacy data from DBs. Thus, a number
at a scale of major DBs would be good. Yes, it's arbitrary. 64K would be good, but 64M or
64G might not be as good.

SQL string comparison semantics, max length, etc.
