### Describe the enhancement requested The method **RowGroupTotalBytesWritten()** is available but only make sense for the ones that use [fileWriter.Write()](https://github.com/apache/arrow-go/blob/main/parquet/pqarrow/file_writer_test.go#L54C21-L54C41) For the ones that use [fileWriter.WriteBuffered()](https://github.com/apache/arrow-go/blob/main/parquet/pqarrow/file_writer_test.go#L131) , it won't populate the bytes written until the writer is closed. We are wondering if there is a way of populating or give an estimation of the size before closing the rowGroupWriter. This would be helpful to determine how large of a parquet file we want to build. ### Component(s) Parquet -- This is an automated message from the Apache Git Service.
