Zheng Shao updated HIVE-270:
----------------------------
Description:
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.
