@@ -163,7 +163,7 @@ In the following scenarios, there can be significant overlap in KV ranges:
     - `IMPORT INTO` splits sub-jobs based on the traversal order of data files, usually sorted by file name in lexicographic order.
 - If the target table has many indexes, or the index column values are scattered in the data file, the index KV generated by the encoding of each sub-job will also overlap.
 
-When the [TiDB Distributed eXecution Framework (DXF)](/tidb-distributed-execution-framework.md) is enabled, you can enable [Global Sort](/tidb-global-sort.md) by specifying the `CLOUD_STORAGE_URI` option in the `IMPORT INTO` statement or by specifying the target storage address for encoded KV data using the system variable [`tidb_cloud_storage_uri`](/system-variables.md#tidb_cloud_storage_uri-new-in-v740). Note that currently, only S3 and GCS are supported as the Global Sort storage address. When Global Sort is enabled, `IMPORT INTO` writes encoded KV data to the cloud storage, performs Global Sort in the cloud storage, and then parallelly imports the globally sorted index and table data into TiKV. This prevents problems caused by KV overlap and enhances import stability.

 Global Sort consumes a significant amount of memory resources. Before the data import, it is recommended to configure the [`tidb_server_memory_limit_gc_trigger`](/system-variables.md#tidb_server_memory_limit_gc_trigger-new-in-v640) and [`tidb_server_memory_limit`](/system-variables.md#tidb_server_memory_limit-new-in-v640) variables, which avoids golang GC being frequently triggered and thus affecting the import efficiency.
