解説
| None | Setting TypeDetectionScheme to None returns all columns as "string" type. Note: Even when set to None, the column names are still scanned. |
| RowScan | Setting TypeDetectionScheme to RowScan scans rows to heuristically determine the data type. The RowScanDepth determines the number of rows that are scanned. If no value is specified, RowScan is used by default. |
