> 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.
