tschaub opened a new issue, #38516: URL: https://github.com/apache/arrow/issues/38516
### Describe the bug, including details regarding any error messages, version, and platform. The `file.Writer` currently increments its `nrows` field in the `writer.Close()` method. https://github.com/apache/arrow/blob/23b62a441ee73ef1643a28e992335b9029f0ebe4/go/parquet/file/file_writer.go#L174-L177 This only accounts for rows written by the last row group writer. In cases where multiple row groups are appended, the total number of rows written is not reported by the `writer.NumRows()` method. ### Component(s) Go, Parquet -- This is an automated message from the Apache Git Service.
