Subject [jira] Commented: (HIVE-732) Hive to use LazyBinarySerDe
Date Thu, 06 Aug 2009 22:34:14 GMT

    [ https://issues.apache.org/jira/browse/HIVE-732?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12740287#action_12740287
] 

Namit Jain commented on HIVE-732:
---------------------------------

Instead of  supporting:

CREATE TABLE xxx (...)
ROW FORMAT BINARY
STORED AS SEQUENCEFILE;


shouldn't we let the user specify the serde 

CREATE TABLE xxx (...)
ROW FORMAT SERDE '....';

I mean the existing syntax.

If we have more binary representations in future, how will we address that ?

> Follow-up on HIVE-640. We should use LazyBinarySerDe in several places in the code to
improve the efficiency: value between map-reduce boundary, temporary tables.
> We should also allow users to create tables stored as binary format.

> CREATE TABLE xxx (...)
> ROW FORMAT BINARY
