Converted to draft because I hit another issue: https://github.com/apache/arrow/issues/14870. The C++ parquet reader does not parse column statistics correctly here: https://github.com/apache/arrow/blob/master/cpp/src/parquet/column_reader.cc#L214 ```cpp // Extracts encoded statistics from V1 and V2 data page headers template <typename H> EncodedStatistics ExtractStatsFromHeader(const H& header) { EncodedStatistics page_statistics; if (!header.__isset.statistics) { return page_statistics; } const format::Statistics& stats = header.statistics; if (stats.__isset.max) { page_statistics.set_max(stats.max); } if (stats.__isset.min) { page_statistics.set_min(stats.min); } if (stats.__isset.null_count) { page_statistics.set_null_count(stats.null_count); } if (stats.__isset.distinct_count) { page_statistics.set_distinct_count(stats.distinct_count); } return page_statistics; } ``` -- This is an automated message from the Apache Git Service.
