Hi Ben, SimpleRecord is pretty old and did not upgraded to a newer concept. You need to extend ParquetReader for SimpleRecord. See AvroParquetReader for details. After you have to specified SimpleRecordReader and the related Builder you can add the methods you need. I also wanted to highlight that parquet-tools is not really for using it from the code but from the command line. There are not proper unit tests for that code and there are no guarantees for backward code compatibility between the releases. I would not recommend using these code parts for production.
