AFAIK, the statistics in the data page header has been deprecated after column index (part of the page index) has been introduced. CMIW, parquet cpp is in good state with the parquet spec: - On the read path, the statistics in the ColumnChunkMetaData already consumes `min_value` & `max_value` from the thrift object if available: https://github.com/apache/arrow/blob/master/cpp/src/parquet/metadata.cc#L97 - On the write path, we have written both `min_value` and `min` for backward-compatibility: https://github.com/apache/arrow/blob/master/cpp/src/parquet/thrift_internal.h#L292 -- This is an automated message from the Apache Git Service.
