| **Compression**         | <p>Specify the codec to use to compress the Parquet Output file:</p><ul><li><strong>None</strong>: No compression is used (default).</li><li><strong>Snappy</strong>: Using Google's <a href="http://google.github.io/snappy/">Snappy</a> compression library, writes the data blocks that are followed by the 4-byte, big-endian CRC32 checksum of the uncompressed data in each block.</li><li><strong>GZIP</strong>: Uses a compression format that is based on the <a href="https://en.wikipedia.org/wiki/DEFLATE">Deflate</a> algorithm.</li></ul> |
| **Version**             | <p>Specify the version of Parquet you want to use:</p><ul><li><strong>Parquet 1.0</strong></li><li><strong>Parquet 2.0</strong></li></ul>                                                                                                                                                                                                                                                                                                                                                                                                               |
| **Row group size (MB)** | Specify the group size for the rows. The default value is 0.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                            |
| **Data page size (KB)** | Specify the page size for the data. The default value is 0.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                             |
| **Dictionary encoding** | Specifies the dictionary encoding, which builds a dictionary of values encountered in a column. The dictionary page is written first, before the data pages of the column. Note that if the dictionary grows larger than the **Page size**, whether in size or number of distinct values, then the encoding method will revert to the plain encoding type.                                                                                                                                                                                              |
| **Page size (KB)**      | Specify the page size when using dictionary encoding. The default value is 1024.                                                                                                                                                                                                                                                                                                                                                                                                                                                                        |
