#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”`).

#escaper ⇒ String

Specifies a character to use for escaping. This option is used only when reading CSV files. The default value is ‘none`. If enabled, the character which immediately follows is used as-is, except for a small set of well-known escapes (`n`, `r`, `t`, and `0`).

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)

  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)

  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)

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)

end

#multiline ⇒ Boolean

A Boolean value that specifies whether a single record can span multiple lines. This can occur when a field contains a quoted new-line character. You must set this option to True if any record spans multiple lines. The default value is ‘False`, which allows for more aggressive file-splitting during parsing.

Returns:

• (Boolean)
