HuaHuaY opened a new pull request, #50694: URL: https://github.com/apache/arrow/pull/50694
### Rationale for this change To prevent negative `null_count` and `distinct_count` values from leading to incorrect statistics-based pruning, we had better to check for negative values. ### What changes are included in this PR? Modify `ColumnIndex::Make`at `cpp/src/parquet/page_index.cc` and `MakeTypedColumnStats` at `cpp/src/parquet/metadata.cc`. When reading `null_count` and `distinct_count` from a file, we no longer silently assume that the values are natural numbers. ### Are these changes tested? Yes. ### Are there any user-facing changes? No. -- This is an automated message from the Apache Git Service. To respond to the message, please log on to GitHub and use the URL above to go to the specific comment.
