Builder

Properties

var additionalOptions: S3DirectSourceAdditionalOptions?

Specifies additional connection options.

var compressionType: ParquetCompressionType?

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").

exclusions

var exclusions: List<String>?

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

groupFiles

var groupFiles: 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".

groupSize

var groupSize: 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.

maxBand

var maxBand: Int?

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.

maxFilesInBand

var maxFilesInBand: Int?

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.

name

var name: String?

The name of the data store.

outputSchemas

var outputSchemas: List<GlueSchema>?

Specifies the data schema for the S3 Parquet source.

paths

var paths: List<String>?

A list of the Amazon S3 paths to read from.

recurse

var recurse: Boolean?

If set to true, recursively reads files in all subdirectories under the specified paths.
