> 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.
