#additional_options ⇒ Types::S3DirectSourceAdditionalOptions

Specifies additional connection options.

Returns:

end

#compression_type ⇒ String

Specifies how the data is compressed. This is generally not necessary if the data has a standard file extension. Possible values are "gzip" and "bzip").

Returns:

• (String)

end

#exclusions ⇒ Array<String>

A string containing a JSON list of Unix-style glob patterns to exclude. For example, "[\"**.pdf\"]" excludes all PDF files.

Returns:

• (Array<String>)

  SENSITIVE = []
  include Aws::Structure
end

#group_files ⇒ String

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:

• (String)

# File 'gems/aws-sdk-glue/lib/aws-sdk-glue/types.rb', line 19159

class S3ParquetSource < Struct.new(
  :name,
  :paths,

  :max_band,
  :max_files_in_band,
  :additional_options,
  :output_schemas)
  SENSITIVE = []
  include Aws::Structure
end

#group_size ⇒ String

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:

• (String)

# File 'gems/aws-sdk-glue/lib/aws-sdk-glue/types.rb', line 19159

class S3ParquetSource < Struct.new(
  :name,
  :paths,

  :recurse,
  :max_band,
  :max_files_in_band,
  :additional_options,
  :output_schemas)
  SENSITIVE = []
  include Aws::Structure
end

#max_band ⇒ Integer

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:

• (Integer)

  SENSITIVE = []
  include Aws::Structure
end

#max_files_in_band ⇒ Integer

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:

• (Integer)
