> Some columnar file formats such as Parquet store fields in struct type also
> column by column using encoding described in Google Dramel pager. It's very
> common in big data where data are stored in structs while queries only needs
> a subset of the the fields in the structs. However, presently Hive still
> needs to read the whole struct regardless whether all fields are selected.
> Therefore, pruning unwanted sub-fields in struct or nested fields at file
> reading time would be a big performance boost for such scenarios.
