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. > Add varchar data type > --------------------- > > Key: HIVE-4844 > URL: https://issues.apache.org/jira/browse/HIVE-4844 > Project: Hive > Issue Type: New Feature > Components: Types > Reporter: Jason Dere > Assignee: Jason Dere > Attachments: HIVE-4844.10.patch, HIVE-4844.11.patch, > HIVE-4844.12.patch, HIVE-4844.1.patch.hack, HIVE-4844.2.patch, > HIVE-4844.3.patch, HIVE-4844.4.patch, HIVE-4844.5.patch, HIVE-4844.6.patch, > HIVE-4844.7.patch, HIVE-4844.8.patch, HIVE-4844.9.patch, > HIVE-4844.D12699.1.patch, screenshot.png > > > Add new varchar data types which have support for more SQL-compliant > behavior, such as SQL string comparison semantics, max length, etc. > Char type will be added as another task. > NO PRECOMMIT TESTS - now dependent on HIVE-5203/5204/5206 -- This message is automatically generated by JIRA.
