etseidl opened a new issue, #8815: URL: https://github.com/apache/arrow-rs/issues/8815
**Describe the bug** While testing #8811 I found that trying to concatenate `alltypes_tiny_pages.parquet` from the parquet-testing repo fails with the error "Cannot serialize NONE index". While creating a Parquet file from scratch, the column index may contain `None` entries. But when reading from a file with missing indexes, a `ColumnIndexMetaData::NONE` will be inserted because the current metadata requires a value. When trying to serialize this, the `ColumnIndexMetaData::NONE` is encountered and triggers the error. **To Reproduce** Use parquet-concat from #8811 on `parquet-testing/data/alltypes_tiny_pages.parquet`. **Expected behavior** A `ColumnIndexMetaData::NONE` should simply be skipped. **Additional context** <!-- Add any other context about the problem here. --> -- This is an automated message from the Apache Git Service.
