运行如下命令将 CSV 源文件生成为 SST 文件。关于参数的说明，请参见[命令参数](../parameter-reference/ex-ug-para-import-command.md)。

```bash
${SPARK_HOME}/bin/spark-submit --master "local" --conf spark.sql.shuffle.partition=<shuffle_concurrency> --class com.vesoft.nebula.exchange.Exchange <nebula-exchange-{{exchange.release}}.jar_path> -c <sst_application.conf_path>

```

!!! note

生成 SST 文件时，会涉及到 Spark 的 shuffle 操作，请注意在提交命令中增加`spark.sql.shuffle.partition`的配置。
