@zeroshade I had a go at implementing support for LargeString/LargeBinary: https://github.com/apache/arrow/pull/33965 A potential gotcha I stumbled on though is that while we can now write out `array.LargeString`, on reads we get `array.String` back. If you're only reading a subset of the dataset at a time (e.g. using the [RecordReader](https://pkg.go.dev/github.com/apache/arrow/go/[email protected]/parquet/pqarrow#FileReader.GetRecordReader)), then things are fine. If you try to read the entire dataset (or column) at once though, then we get back to the original error in this issue. Presumably writing with: `pqarrow.NewArrowWriterProperties(pqarrow.WithStoreSchema())` is supposed to fix this but just hasn't been implemented yet? Aside: I found it humorous that the cpp side of things also [errors out](https://github.com/apache/arrow/issues/21526#issuecomment-1377761216) -- This is an automated message from the Apache Git Service.
