   I have customers file set (table, writer id - "parquet-mr compatible Photon version 0.2")
   where min/max_value are set for string column with undefined order - current implementation ignores them.
   In general, for row group filtering (using range predicate by min/max) sort order does not matter,
   only the correct min/max values are needed.
