  • Method Details

    • getBlockSizeBytes

      @Stability(Stable) @Nullable default Number getBlockSizeBytes()
      The Hadoop Distributed File System (HDFS) block size.

      This is useful if you intend to copy the data from Amazon S3 to HDFS before querying. The default is 256 MiB and the minimum is 64 MiB. Kinesis Data Firehose uses this value for padding calculations.

    • getCompression

      @Stability(Stable) @Nullable default String getCompression()
      The compression code to use over data blocks.

      The possible values are UNCOMPRESSED , SNAPPY , and GZIP , with the default being SNAPPY . Use SNAPPY for higher decompression speed. Use GZIP if the compression ratio is more important than speed.

    • getEnableDictionaryCompression

      @Stability(Stable) @Nullable default Object getEnableDictionaryCompression()
      Indicates whether to enable dictionary compression.
    • getMaxPaddingBytes

      @Stability(Stable) @Nullable default Number getMaxPaddingBytes()
      The maximum amount of padding to apply.

      This is useful if you intend to copy the data from Amazon S3 to HDFS before querying. The default is 0.

    • getPageSizeBytes

      @Stability(Stable) @Nullable default Number getPageSizeBytes()
      The Parquet page size.

      Column chunks are divided into pages. A page is conceptually an indivisible unit (in terms of compression and encoding). The minimum value is 64 KiB and the default is 1 MiB.

    • getWriterVersion

      @Stability(Stable) @Nullable default String getWriterVersion()
      Indicates the version of row format to output.

      The possible values are V1 and V2 . The default is V1 .

    • builder

      @Stability(Stable) static CfnDeliveryStream.ParquetSerDeProperty.Builder builder()
      a CfnDeliveryStream.ParquetSerDeProperty.Builder of CfnDeliveryStream.ParquetSerDeProperty
