Expand description
Specifies an Apache Parquet data store stored in Amazon S3.
Fields (Non-exhaustive)§
This struct is marked as non-exhaustive
Struct { .. }
syntax; cannot be matched against without a wildcard ..
; and struct update syntax will not work.name: String
The name of the data store.
paths: Vec<String>
A list of the Amazon S3 paths to read from.
compression_type: Option<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: Option<Vec<String>>
A string containing a JSON list of Unix-style glob patterns to exclude. For example, "\[\"**.pdf\"\]" excludes all PDF files.
group_size: Option<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.
group_files: Option<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"
.
recurse: Option<bool>
If set to true, recursively reads files in all subdirectories under the specified paths.
max_band: Option<i32>
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.
max_files_in_band: Option<i32>
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.
additional_options: Option<S3DirectSourceAdditionalOptions>
Specifies additional connection options.
output_schemas: Option<Vec<GlueSchema>>
Specifies the data schema for the S3 Parquet source.

sourcepub fn compression_type(&self) -> Option<&ParquetCompressionType>
pub fn compression_type(&self) -> Option<&ParquetCompressionType>
Specifies how the data is compressed. This is generally not necessary if the data has a standard file extension. Possible values are "gzip"

).
sourcepub fn exclusions(&self) -> &[String]
pub fn exclusions(&self) -> &[String]
A string containing a JSON list of Unix-style glob patterns to exclude. For example, "\[\"**.pdf\"\]" excludes all PDF files.
If no value was sent for this field, a default will be set. If you want to determine if no value was sent, use .exclusions.is_none()
.
sourcepub fn group_size(&self) -> Option<&str>
pub fn group_size(&self) -> Option<&str>
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.
sourcepub fn group_files(&self) -> Option<&str>
pub fn group_files(&self) -> Option<&str>
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"

pub fn recurse(&self) -> Option<bool>
If set to true, recursively reads files in all subdirectories under the specified paths.
sourcepub fn max_band(&self) -> Option<i32>
pub fn max_band(&self) -> Option<i32>
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.

sourcepub fn max_files_in_band(&self) -> Option<i32>
pub fn max_files_in_band(&self) -> Option<i32>
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.
sourcepub fn additional_options(&self) -> Option<&S3DirectSourceAdditionalOptions>
pub fn additional_options(&self) -> Option<&S3DirectSourceAdditionalOptions>
Specifies additional connection options.
sourcepub fn output_schemas(&self) -> &[GlueSchema]
pub fn output_schemas(&self) -> &[GlueSchema]
Specifies the data schema for the S3 Parquet source.
If no value was sent for this field, a default will be set. If you want to determine if no value was sent, use .output_schemas.is_none()
.
