  • Method Details

    • stripeSizeBytes

      OrcSerDe.Builder stripeSizeBytes(Integer stripeSizeBytes)

      The number of bytes in each stripe. The default is 64 MiB and the minimum is 8 MiB.

      Parameters:
      stripeSizeBytes - The number of bytes in each stripe. The default is 64 MiB and the minimum is 8 MiB.
      Returns:
      Returns a reference to this object so that method calls can be chained together.

    • blockSizeBytes

      OrcSerDe.Builder blockSizeBytes(Integer 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.

      Parameters:
      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.
      Returns:
      Returns a reference to this object so that method calls can be chained together.

    • rowIndexStride

      OrcSerDe.Builder rowIndexStride(Integer rowIndexStride)

      The number of rows between index entries. The default is 10,000 and the minimum is 1,000.

      Parameters:
      rowIndexStride - The number of rows between index entries. The default is 10,000 and the minimum is 1,000.
      Returns:
      Returns a reference to this object so that method calls can be chained together.

    • enablePadding

      OrcSerDe.Builder enablePadding(Boolean 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.

      Parameters:
      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.
      Returns:
      Returns a reference to this object so that method calls can be chained together.

    • paddingTolerance

      OrcSerDe.Builder paddingTolerance(Double 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 OrcSerDe$EnablePadding is false.

      Parameters:
      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 OrcSerDe$EnablePadding is false.

      Returns:
      Returns a reference to this object so that method calls can be chained together.

    • compression

      OrcSerDe.Builder compression(String compression)

      The compression code to use over data blocks. The default is SNAPPY.

      Parameters:
      compression - The compression code to use over data blocks. The default is SNAPPY.
      Returns:
      Returns a reference to this object so that method calls can be chained together.

    • bloomFilterColumns

      OrcSerDe.Builder bloomFilterColumns(Collection<String> bloomFilterColumns)

      The column names for which you want Kinesis Data Firehose to create bloom filters. The default is null.

      Parameters:
      bloomFilterColumns - The column names for which you want Kinesis Data Firehose to create bloom filters. The default is null.
      Returns:
      Returns a reference to this object so that method calls can be chained together.

    • bloomFilterColumns

      OrcSerDe.Builder bloomFilterColumns(String... bloomFilterColumns)

      The column names for which you want Kinesis Data Firehose to create bloom filters. The default is null.

      Parameters:

    • bloomFilterFalsePositiveProbability

      OrcSerDe.Builder bloomFilterFalsePositiveProbability(Double 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.

      Parameters:
      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.

    • dictionaryKeyThreshold

      OrcSerDe.Builder dictionaryKeyThreshold(Double 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.

      Parameters:
      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.
