Start by locating the fetch_result_rows_rate metric and the handling for the kyuubi.operation.result.format setting when it is set to arrow. Reproduce the reported behavior on version 1.8.0 and trace how result rows are counted; done means the metric reports the correct rate for arrow-format results.
