Spark is a row-based compute engine. The reason why you see `ColumnarToRow` is that Spark has vectorized `parquet` / `iceberg` reader. Once the vectorized reader finishes, Spark has to convert it back to row-based layout. The reason why you didn't see it in `geoparquet` reader, it is because Sedona's GeoParquet reader has not support vectorized read yet. -- This is an automated message from the Apache Git Service.
