All Known Implementing Classes:

CfnDeliveryStream.ParquetSerDeProperty.Jsii$Proxy

Enclosing class:

CfnDeliveryStream

public static interface CfnDeliveryStream.ParquetSerDeProperty

A serializer to use for converting data to the Parquet format before storing it in Amazon S3.

For more information, see Apache Parquet .

Example:

 // The code below shows an example of how to instantiate this type.
 // The values are placeholders you should change.
 import software.amazon.awscdk.services.kinesisfirehose.*;

Method Detail

getBlockSizeBytes

default java.lang.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

default java.lang.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

default java.lang.Object getEnableDictionaryCompression()

Indicates whether to enable dictionary compression.

getMaxPaddingBytes

default java.lang.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

default java.lang.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

default java.lang.String getWriterVersion()

Indicates the version of row format to output.

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

builder

static CfnDeliveryStream.ParquetSerDeProperty.Builder builder()

Returns:

a CfnDeliveryStream.ParquetSerDeProperty.Builder of CfnDeliveryStream.ParquetSerDeProperty
