concurrently export data. The `parallelism` parameter specifies the number of
threads to execute the `EXPORT Job`. When you set `"data_consistency" = "none"`

The underlying execution logic of an `Export Job `is actually the `SELECT
INTO OUTFILE` statement. Each thread specified by the `parallelism` parameter
executes independent `SELECT INTO OUTFILE` statements.
