Fields

Instances
Create a value of S3DataSource with all optional fields omitted.
Use generic-lens or optics to modify other optional fields.
The following record fields are available, with the corresponding lenses provided for backwards compatibility:
$sel:attributeNames:S3DataSource', s3DataSource_attributeNames - A list of one or more attribute names to use that are found in a
 specified augmented manifest file.
$sel:instanceGroupNames:S3DataSource', s3DataSource_instanceGroupNames - A list of names of instance groups that get data from the S3 data
 source.
$sel:s3DataDistributionType:S3DataSource', s3DataSource_s3DataDistributionType - If you want SageMaker to replicate the entire dataset on each ML compute
 instance that is launched for model training, specify FullyReplicated.
If you want SageMaker to replicate a subset of data on each ML compute
 instance that is launched for model training, specify ShardedByS3Key.
 If there are n ML compute instances launched for a training job, each
 instance gets approximately 1/n of the number of S3 objects. In this
 case, model training on each machine uses only the subset of training
 data.
Don't choose more ML compute instances for training than available S3 objects. If you do, some nodes won't get any data and you will pay for nodes that aren't getting any training data. This applies in both File and Pipe modes. Keep this in mind when developing algorithms.
In distributed training, where you use multiple ML compute EC2
 instances, you might choose ShardedByS3Key. If the algorithm requires
 copying training data to the ML storage volume (when TrainingInputMode
 is set to File), this copies 1/n of the number of objects.
$sel:s3DataType:S3DataSource', s3DataSource_s3DataType - If you choose S3Prefix, S3Uri identifies a key name prefix.
 SageMaker uses all objects that match the specified key name prefix for
 model training.
If you choose ManifestFile, S3Uri identifies an object that is a
 manifest file containing a list of object keys that you want SageMaker
 to use for model training.
If you choose AugmentedManifestFile, S3Uri identifies an object that
 is an augmented manifest file in JSON lines format. This file contains
 the data you want to use for model training. AugmentedManifestFile can
 only be used if the Channel's input mode is Pipe.
$sel:s3Uri:S3DataSource', s3DataSource_s3Uri - Depending on the value specified for the S3DataType, identifies either
 a key name prefix or a manifest. For example:
- A key name prefix might look like this:
     
s3://bucketname/exampleprefix A manifest might look like this:
s3://bucketname/example.manifestA manifest is an S3 object which is a JSON file consisting of an array of elements. The first element is a prefix which is followed by one or more suffixes. SageMaker appends the suffix elements to the prefix to get a full set of
S3Uri. Note that the prefix must be a valid non-emptyS3Urithat precludes users from specifying a manifest whose individualS3Uriis sourced from different S3 buckets.The following code example shows a valid manifest format:
[ {"prefix": "s3://customer_bucket/some/prefix/"},"relative/path/to/custdata-1",
"relative/path/custdata-2",
...
"relative/path/custdata-N"
]
This JSON is equivalent to the following
S3Urilist:s3://customer_bucket/some/prefix/relative/path/to/custdata-1
s3://customer_bucket/some/prefix/relative/path/custdata-2
...
s3://customer_bucket/some/prefix/relative/path/custdata-N
The complete set of
S3Uriin this manifest is the input data for the channel for this data source. The object that eachS3Uripoints to must be readable by the IAM role that SageMaker uses to perform tasks on your behalf.
s3DataSource_attributeNames :: Lens' S3DataSource (Maybe [Text]) Source #
A list of one or more attribute names to use that are found in a specified augmented manifest file.
s3DataSource_instanceGroupNames :: Lens' S3DataSource (Maybe [Text]) Source #
A list of names of instance groups that get data from the S3 data source.
s3DataSource_s3DataDistributionType :: Lens' S3DataSource (Maybe S3DataDistribution) Source #
If you want SageMaker to replicate the entire dataset on each ML compute
