CfnModelPackage.S3DataSourceProperty.getS3DataType()
s3DataType
- If you choose `S3Prefix` , `S3Uri` identifies a key name prefix. This parameter is required.
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
.

public CfnModelPackage.S3DataSourceProperty.Builder s3Uri(java.lang.String s3Uri)
CfnModelPackage.S3DataSourceProperty.getS3Uri()
s3Uri
- Depending on the value specified for the `S3DataType` , identifies either a key name prefix or a manifest. This parameter is required.
For example:
s3://bucketname/exampleprefix
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 complete set of S3Uri
in this manifest is the input data for the channel for this data source. The object that each S3Uri
points to must be readable by the IAM role that SageMaker uses to perform tasks on your behalf.
