Method Details

getBlockSize

public final Size getBlockSize()

Description copied from interface: OrcOutputFormatProps

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. Firehose uses this value for padding calculations.

Default: `Size.mebibytes(256)`

Specified by:

getBlockSize in interface OrcOutputFormatProps

getBloomFilterColumns

public final List<String> getBloomFilterColumns()

Description copied from interface: OrcOutputFormatProps

The column names for which you want Firehose to create bloom filters.

Default: no bloom filters are created

Specified by:

getBloomFilterColumns in interface OrcOutputFormatProps

getBloomFilterFalsePositiveProbability

public final Number getBloomFilterFalsePositiveProbability()

Description copied from interface: OrcOutputFormatProps

The Bloom filter false positive probability (FPP).

The lower the FPP, the bigger the bloom filter.

Default: `0.05`

Specified by:

getBloomFilterFalsePositiveProbability in interface OrcOutputFormatProps

See Also:

• https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-kinesisfirehose-deliverystream-orcserde.html#cfn-kinesisfirehose-deliverystream-orcserde-bloomfilterfalsepositiveprobability

getCompression

public final OrcCompression getCompression()

Description copied from interface: OrcOutputFormatProps

The compression code to use over data blocks.

The possible values are NONE , SNAPPY , and ZLIB. Use SNAPPY for higher decompression speed. Use GZIP if the compression ratio is more important than speed.

Default: `SNAPPY`

Specified by:

getCompression in interface OrcOutputFormatProps

See Also:

• https://docs.aws.amazon.com/AWSCloudFormation/latest/TemplateReference/aws-properties-kinesisfirehose-deliverystream-orcserde.html#cfn-kinesisfirehose-deliverystream-orcserde-compression

getDictionaryKeyThreshold

public final Number getDictionaryKeyThreshold()

Description copied from interface: OrcOutputFormatProps

Determines whether dictionary encoding should be applied to a column.

If the number of distinct keys (unique values) in a column exceeds this fraction of the total non-null rows in that column, dictionary encoding will be turned off for that specific column.

To turn off dictionary encoding, set this threshold to 0. To always use dictionary encoding, set this threshold to 1.

Default: `0.8`

Specified by:

getDictionaryKeyThreshold in interface OrcOutputFormatProps

See Also:

• https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-kinesisfirehose-deliverystream-orcserde.html#cfn-kinesisfirehose-deliverystream-orcserde-dictionarykeythreshold

getEnablePadding

public final Boolean getEnablePadding()

Description copied from interface: OrcOutputFormatProps

Set this to true to indicate that you want stripes to be padded to the HDFS block boundaries.

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

Default: `false`

Specified by:

getEnablePadding in interface OrcOutputFormatProps

See Also:

• https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-kinesisfirehose-deliverystream-orcserde.html#cfn-kinesisfirehose-deliverystream-orcserde-enablepadding

getFormatVersion

public final OrcFormatVersion getFormatVersion()

Description copied from interface: OrcOutputFormatProps

The version of the ORC format to write.

The possible values are V0_11 and V0_12.

Default: `V0_12`

Specified by:

getFormatVersion in interface OrcOutputFormatProps

See Also:

• https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-kinesisfirehose-deliverystream-orcserde.html#cfn-kinesisfirehose-deliverystream-orcserde-formatversion

getPaddingTolerance

public final Number getPaddingTolerance()

Description copied from interface: OrcOutputFormatProps

A number between 0 and 1 that defines the tolerance for block padding as a decimal fraction of stripe size.

The default value is 0.05, which means 5 percent of stripe size.

For the default values of 64 MiB ORC stripes and 256 MiB HDFS blocks, the default block padding tolerance of 5 percent reserves a maximum of 3.2 MiB for padding within the 256 MiB block. In such a case, if the available size within the block is more than 3.2 MiB, a new, smaller stripe is inserted to fit within that space. This ensures that no stripe crosses block boundaries and causes remote reads within a node-local task.

Kinesis Data Firehose ignores this parameter when EnablePadding is false .

Default: `0.05` if `enablePadding` is `true`

Specified by:

getPaddingTolerance in interface OrcOutputFormatProps

See Also:

• https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-kinesisfirehose-deliverystream-orcserde.html#cfn-kinesisfirehose-deliverystream-orcserde-paddingtolerance

getRowIndexStride

public final Number getRowIndexStride()

Description copied from interface: OrcOutputFormatProps

The number of rows between index entries.

Default: 10000

Specified by:

getRowIndexStride in interface OrcOutputFormatProps

See Also:

• https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-kinesisfirehose-deliverystream-orcserde.html#cfn-kinesisfirehose-deliverystream-orcserde-rowindexstride

getStripeSize

public final Size getStripeSize()

Description copied from interface: OrcOutputFormatProps

The number of bytes in each stripe.

The default is 64 MiB and the minimum is 8 MiB.

Default: `Size.mebibytes(64)`

Specified by:

getStripeSize in interface OrcOutputFormatProps

See Also:

• https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-kinesisfirehose-deliverystream-orcserde.html#cfn-kinesisfirehose-deliverystream-orcserde-stripesizebytes
