/**
 * OutputFormat to write to a Parquet file
 * <p>
 * It requires a {@link WriteSupport} to convert the actual records to the underlying format.
 * It requires the schema of the incoming records. (provided by the write support)
 * It allows storing extra metadata in the footer (for example: for schema compatibility purpose when converting from a different schema language).
 * <p>
 * The format configuration settings in the job configuration:
 * <pre>
 * # The block size is the size of a row group being buffered in memory
 * # this limits the memory usage when writing
 * # Larger values will improve the IO when reading but consume more memory when writing
 * parquet.block.size=134217728 # in bytes, default = 128 * 1024 * 1024
 *
 * # The page size is for compression. When reading, each page can be decompressed independently.
 * # A block is composed of pages. The page is the smallest unit that must be read fully to access a single record.
 * # If this value is too small, the compression will deteriorate
 * parquet.page.size=1048576 # in bytes, default = 1 * 1024 * 1024
 *
 * # There is one dictionary page per column per row group when dictionary encoding is used.
 * # The dictionary page size works like the page size but for dictionary
 * parquet.dictionary.page.size=1048576 # in bytes, default = 1 * 1024 * 1024
 *
 * # The compression algorithm used to compress pages
 * parquet.compression=UNCOMPRESSED # one of: UNCOMPRESSED, SNAPPY, GZIP, LZO, ZSTD. Default: UNCOMPRESSED. Supersedes mapred.output.compress*
 *
 * # The write support class to convert the records written to the OutputFormat into the events accepted by the record consumer
 * # Usually provided by a specific ParquetOutputFormat subclass
 * parquet.write.support.class= # fully qualified name
 *
 * # To enable/disable dictionary encoding
 * parquet.enable.dictionary=true # false to disable dictionary encoding
 *
 * # To enable/disable BYTE_STREAM_SPLIT encoding
 * parquet.enable.bytestreamsplit=false # true to enable BYTE_STREAM_SPLIT encoding
 *
 * # To enable/disable summary metadata aggregation at the end of a MR job
 * # The default is true (enabled)
 * parquet.enable.summary-metadata=true # false to disable summary aggregation
 *
 * # Maximum size (in bytes) allowed as padding to align row groups
 * # This is also the minimum size of a row group. Default: 8388608
 * parquet.writer.max-padding=8388608 # 8 MB
 * </pre>
 * <p>
 * If parquet.compression is not set, the following properties are checked (FileOutputFormat behavior).
 * Note that we explicitely disallow custom Codecs
 * <pre>
 * mapred.output.compress=true
 * mapred.output.compression.codec=org.apache.hadoop.io.compress.SomeCodec # the codec must be one of Snappy, GZip or LZO
 * </pre>
 * <p>
 * if none of those is set the data is uncompressed.
