@Stability(Stable)
public static interface CfnDeliveryStream.ParquetSerDeProperty
extends software.amazon.jsii.JsiiSerializable

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.*;
 ParquetSerDeProperty parquetSerDeProperty = ParquetSerDeProperty.builder()

         .pageSizeBytes(123)
         .writerVersion("writerVersion")
         .build();

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. Firehose uses this value for padding calculations.

See Also:

• http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-kinesisfirehose-deliverystream-parquetserde.html#cfn-kinesisfirehose-deliverystream-parquetserde-blocksizebytes

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.

• http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-kinesisfirehose-deliverystream-parquetserde.html#cfn-kinesisfirehose-deliverystream-parquetserde-compression

getEnableDictionaryCompression

@Stability(Stable)
@Nullable
default Object getEnableDictionaryCompression()

Indicates whether to enable dictionary compression.

See Also:

• http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-kinesisfirehose-deliverystream-parquetserde.html#cfn-kinesisfirehose-deliverystream-parquetserde-enabledictionarycompression

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.

See Also:

• http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-kinesisfirehose-deliverystream-parquetserde.html#cfn-kinesisfirehose-deliverystream-parquetserde-maxpaddingbytes

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.

See Also:

• http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-kinesisfirehose-deliverystream-parquetserde.html#cfn-kinesisfirehose-deliverystream-parquetserde-pagesizebytes

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 .

• http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-kinesisfirehose-deliverystream-parquetserde.html#cfn-kinesisfirehose-deliverystream-parquetserde-writerversion

builder

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

Returns:

a CfnDeliveryStream.ParquetSerDeProperty.Builder of CfnDeliveryStream.ParquetSerDeProperty
