> According to parquet format specification columns annotated as DECIMAL should use SIGNED comparator and statistics should be available. The sort order returned by {{org.apache.parquet.format.converter.ParquetMetadataConverter}} for DECIMAL is {{SortOrder.UNKNOWN}} which contradicts the specification and makes statistics for DECIMAL types unavailable.
