Detailed Description

Holds column names and buffers containing raw file-level and stripe-level statistics.

The buffers can be parsed using a Protobuf parser. Alternatively, use parsed_orc_statistics to get the statistics parsed into a libcudf representation.

The column_names and file_stats members contain one element per column. The stripes_stats contains one element per stripe, where each element contains column statistics for each column.
