Overview

A serializer to use for converting data to the Parquet format before storing it in Amazon S3. For more information, see Apache Parquet.

  blockSizeBytes

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.

@property (nonatomic, strong) NSNumber *blockSizeBytes

Declared In

AWSFirehoseModel.h

  compression

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 ration is more important than speed.

@property (nonatomic, assign) AWSFirehoseParquetCompression compression

AWSFirehoseModel.h

  enableDictionaryCompression

Indicates whether to enable dictionary compression.

@property (nonatomic, strong) NSNumber *enableDictionaryCompression

Declared In

AWSFirehoseModel.h

  maxPaddingBytes

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.

@property (nonatomic, strong) NSNumber *maxPaddingBytes

Declared In

AWSFirehoseModel.h

  pageSizeBytes

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.

@property (nonatomic, strong) NSNumber *pageSizeBytes

  writerVersion

Indicates the version of row format to output. The possible values are V1 and V2. The default is V1.
