      • groupSize

        S3ParquetSource.Builder groupSize​(String groupSize)

        The target group size in bytes. The default is computed based on the input data size and the size of your cluster. When there are fewer than 50,000 input files, "groupFiles" must be set to "inPartition" for this to take effect.

        Parameters:
        groupSize - The target group size in bytes. The default is computed based on the input data size and the size of your cluster. When there are fewer than 50,000 input files, "groupFiles" must be set to "inPartition" for this to take effect.
        Returns:

      • groupFiles

        S3ParquetSource.Builder groupFiles​(String groupFiles)

        Grouping files is turned on by default when the input contains more than 50,000 files. To turn on grouping with fewer than 50,000 files, set this parameter to "inPartition". To disable grouping when there are more than 50,000 files, set this parameter to "none".

        Parameters:
        groupFiles - Grouping files is turned on by default when the input contains more than 50,000 files. To turn on grouping with fewer than 50,000 files, set this parameter to "inPartition". To disable grouping when there are more than 50,000 files, set this parameter to "none".
        Returns:
        Returns a reference to this object so that method calls can be chained together.

      • recurse

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

      • maxBand

        S3ParquetSource.Builder maxBand​(Integer maxBand)

        This option controls the duration in milliseconds after which the s3 listing is likely to be consistent. Files with modification timestamps falling within the last maxBand milliseconds are tracked specially when using JobBookmarks to account for Amazon S3 eventual consistency. Most users don't need to set this option. The default is 900000 milliseconds, or 15 minutes.

        Parameters:
        maxBand - This option controls the duration in milliseconds after which the s3 listing is likely to be consistent. Files with modification timestamps falling within the last maxBand milliseconds are tracked specially when using JobBookmarks to account for Amazon S3 eventual consistency. Most users don't need to set this option. The default is 900000 milliseconds, or 15 minutes.
        Returns:
        Returns a reference to this object so that method calls can be chained together.

      • maxFilesInBand

        S3ParquetSource.Builder maxFilesInBand​(Integer maxFilesInBand)

        This option specifies the maximum number of files to save from the last maxBand seconds. If this number is exceeded, extra files are skipped and only processed in the next job run.

        Parameters:
        maxFilesInBand - This option specifies the maximum number of files to save from the last maxBand seconds. If this number is exceeded, extra files are skipped and only processed in the next job run.
        Returns:
        Returns a reference to this object so that method calls can be chained together.

      • additionalOptions

        S3ParquetSource.Builder additionalOptions​(S3DirectSourceAdditionalOptions additionalOptions)
