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.
> Add a lazy-deserialized SerDe for space and cpu efficient serialization of
> rows with primitive types

> We want to add a lazy-deserialized SerDe for space and cpu efficient
> serialization of rows with primitive types.
> 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.
