S3DataTypepublic void setS3Uri(String 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.manifest
A 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-empty S3Uri that precludes users
from specifying a manifest whose individual S3Uri is 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 S3Uri list:
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 object that each S3Uri points to must be readable by the IAM role that Amazon SageMaker uses to
perform tasks on your behalf.

public void setS3DataDistributionType(String s3DataDistributionType)
If you want Amazon SageMaker to replicate the entire dataset on each ML compute instance that is launched for
model training, specify FullyReplicated.
If you want Amazon 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.
