 #### `WITH` Option
 
 `WITH` adds options such as the file `FORMAT` which specifies the format of the exported file. In this example, the format is Parquet; it is a columnar storage format used for big data processing. Parquet efficiently compresses and encodes columnar data for big data analytics.
