@@ -149,7 +149,7 @@ The supported options are described as follows:
 | `SKIP_ROWS=<number>` | CSV | Specifies the number of rows to skip. The default value is `0`. You can use this option to skip the header in a CSV file. If you use a wildcard to specify the source files for import, this option applies to all source files that are matched by the wildcard in `fileLocation`. |
 | `SPLIT_FILE` | CSV | Splits a single CSV file into multiple smaller chunks of around 256 MiB for parallel processing to improve import efficiency. This parameter only works for **non-compressed** CSV files and has the same usage restrictions as that of TiDB Lightning [`strict-format`](https://docs.pingcap.com/tidb/stable/tidb-lightning-data-source#strict-format). Note that you need to explicitly specify `LINES_TERMINATED_BY` for this option. |
 | `DISK_QUOTA='<string>'` | All file formats | Specifies the disk space threshold that can be used during data sorting. The default value is 80% of the disk space in the TiDB [temporary directory](https://docs.pingcap.com/tidb/stable/tidb-configuration-file#temp-dir-new-in-v630). If the total disk size cannot be obtained, the default value is 50 GiB. When specifying `DISK_QUOTA` explicitly, make sure that the value does not exceed 80% of the disk space in the TiDB temporary directory. |
-| `DISABLE_TIKV_IMPORT_MODE` | All file formats | Specifies whether to disable switching TiKV to import mode during the import process. By default, switching TiKV to import mode is not disabled. If there are ongoing read-write operations in the cluster, you can enable this option to avoid impact from the import process. |
+| `DISABLE_TIKV_IMPORT_MODE` | All file formats | Specifies whether to disable switching TiKV to import mode during the import process. By default, switching TiKV to import mode is not disabled. If there are ongoing read-write operations in the cluster, you can enable this option to avoid impact from the import process. Since version v9.0.0-xx(next release version), when import using global sort, switching TiKV to import mode is disabled. |
 | `THREAD=<number>` | All file formats and query results of `SELECT` | Specifies the concurrency for import. For `IMPORT INTO ... FROM FILE`, the default value of `THREAD` is 50% of the number of CPU cores on the TiDB node, the minimum value is `1`, and the maximum value is the number of CPU cores. For `IMPORT INTO ... FROM SELECT`, the default value of `THREAD` is `2`, the minimum value is `1`, and the maximum value is two times the number of CPU cores on the TiDB node. To import data into a new cluster without any data, it is recommended to increase this concurrency appropriately to improve import performance. If the target cluster is already used in a production environment, it is recommended to adjust this concurrency according to your application requirements. |
 | `MAX_WRITE_SPEED='<string>'` | All file formats | Controls the write speed to a TiKV node. By default, there is no speed limit. For example, you can specify this option as `1MiB` to limit the write speed to 1 MiB/s. |
 | `CHECKSUM_TABLE='<string>'` | All file formats | Configures whether to perform a checksum check on the target table after the import to validate the import integrity. The supported values include `"required"` (default), `"optional"`, and `"off"`. `"required"` means performing a checksum check after the import. If the checksum check fails, TiDB will return an error and the import will exit. `"optional"` means performing a checksum check after the import. If an error occurs, TiDB will return a warning and ignore the error. `"off"` means not performing a checksum check after the import. |
