public CfnDeliveryStream.OrcSerDeProperty.Builder blockSizeBytes(java.lang.Number blockSizeBytes)
CfnDeliveryStream.OrcSerDeProperty.getBlockSizeBytes()
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.this
public CfnDeliveryStream.OrcSerDeProperty.Builder bloomFilterColumns(java.util.List<java.lang.String> bloomFilterColumns)
CfnDeliveryStream.OrcSerDeProperty.getBloomFilterColumns()
bloomFilterColumns
- The column names for which you want Kinesis Data Firehose to create bloom filters.
The default is null
.this
public CfnDeliveryStream.OrcSerDeProperty.Builder bloomFilterFalsePositiveProbability(java.lang.Number bloomFilterFalsePositiveProbability)
bloomFilterFalsePositiveProbability
- The Bloom filter false positive probability (FPP).
The lower the FPP, the bigger the Bloom filter. The default value is 0.05, the minimum is 0, and the maximum is 1.this
public CfnDeliveryStream.OrcSerDeProperty.Builder compression(java.lang.String compression)
CfnDeliveryStream.OrcSerDeProperty.getCompression()
compression
- The compression code to use over data blocks.
The default is SNAPPY
.this
public CfnDeliveryStream.OrcSerDeProperty.Builder dictionaryKeyThreshold(java.lang.Number dictionaryKeyThreshold)
CfnDeliveryStream.OrcSerDeProperty.getDictionaryKeyThreshold()
dictionaryKeyThreshold
- Represents the fraction of the total number of non-null rows.
To turn off dictionary encoding, set this fraction to a number that is less than the number of distinct keys in a dictionary. To always use dictionary encoding, set this threshold to 1.this
public CfnDeliveryStream.OrcSerDeProperty.Builder enablePadding(java.lang.Boolean enablePadding)
CfnDeliveryStream.OrcSerDeProperty.getEnablePadding()
enablePadding
- 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. The default is false
.this
public CfnDeliveryStream.OrcSerDeProperty.Builder enablePadding(IResolvable enablePadding)
CfnDeliveryStream.OrcSerDeProperty.getEnablePadding()
enablePadding
- 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. The default is false
.this
public CfnDeliveryStream.OrcSerDeProperty.Builder formatVersion(java.lang.String formatVersion)
CfnDeliveryStream.OrcSerDeProperty.getFormatVersion()
formatVersion
- The version of the file to write.
The possible values are V0_11
and V0_12
. The default is V0_12
.this
public CfnDeliveryStream.OrcSerDeProperty.Builder paddingTolerance(java.lang.Number paddingTolerance)
CfnDeliveryStream.OrcSerDeProperty.getPaddingTolerance()
paddingTolerance
- 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
.
this
public CfnDeliveryStream.OrcSerDeProperty.Builder rowIndexStride(java.lang.Number rowIndexStride)
CfnDeliveryStream.OrcSerDeProperty.getRowIndexStride()
rowIndexStride
- The number of rows between index entries.
The default is 10,000 and the minimum is 1,000.this
public CfnDeliveryStream.OrcSerDeProperty.Builder stripeSizeBytes(java.lang.Number stripeSizeBytes)
CfnDeliveryStream.OrcSerDeProperty.getStripeSizeBytes()
stripeSizeBytes
- The number of bytes in each stripe.
The default is 64 MiB and the minimum is 8 MiB.this
public CfnDeliveryStream.OrcSerDeProperty build()

java.lang.NullPointerException
