wgtmac opened a new issue, #34138:
URL: https://github.com/apache/arrow/issues/34138
### Describe the bug, including details regarding any error messages,
version, and platform.
The code below does not check and read from stats.min_value/max_value. If
reading from a parquet file where the stats apply min_value/max_value, we are
unable to read any column statistics at all.
```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;
}
```
