[jira] Updated: (HIVE-270) Add a lazy-deserialized SerDe for space and cpu efficient serialization of rows with primitive types
[ https://issues.apache.org/jira/browse/HIVE-270?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Zheng Shao updated HIVE-270: Attachment: HIVE-270.4.patch After looking at the code again, I decided to postpone the change of serialization until we move from String to Text. With that change, we will be able to get rid of all UTF-8 encoding in the serialization. This patch incorporates all other comments from Joydeep.

This SerDe will share the same format as MetadataTypedColumnsetSerDe/TCTLSeparatedProtocol to be backward compatible. This SerDe will be used to replace the default table SerDe, and the SerDe used to communicate with user scripts. For simplicity, we don't plan to support nested structure with this SerDe. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
