Creates a DataSource
from a database hosted on an Amazon Redshift
cluster. A DataSource
references data that can be used to perform
either CreateMLModel
, CreateEvaluation
, or CreateBatchPrediction
operations.
CreateDataSourceFromRedshift
is an asynchronous operation. In response
to CreateDataSourceFromRedshift
, Amazon Machine Learning (Amazon ML)
immediately returns and sets the DataSource
status to PENDING
. After
the DataSource
is created and ready for use, Amazon ML sets the
Status
parameter to COMPLETED
. DataSource
in COMPLETED
or
PENDING
states can be used to perform only CreateMLModel
,
CreateEvaluation
, or CreateBatchPrediction
operations.
If Amazon ML can't accept the input source, it sets the Status
parameter to FAILED
and includes an error message in the Message
attribute of the GetDataSource
operation response.
The observations should be contained in the database hosted on an Amazon
Redshift cluster and should be specified by a SelectSqlQuery
query.
Amazon ML executes an Unload
command in Amazon Redshift to transfer
the result set of the SelectSqlQuery
query to S3StagingLocation
.
After the DataSource
has been created, it's ready for use in
evaluations and batch predictions. If you plan to use the DataSource
to train an MLModel
, the DataSource
also requires a recipe. A recipe
describes how each input variable will be used in training an MLModel
.
Will the variable be included or excluded from training? Will the
variable be manipulated; for example, will it be combined with another
variable or will it be split apart into word combinations? The recipe
provides answers to these questions.
You can't change an existing datasource, but you can copy and modify
the settings from an existing Amazon Redshift datasource to create a new
datasource. To do so, call GetDataSource
for an existing datasource
and copy the values to a CreateDataSource
call. Change the settings
that you want to change and make sure that all required fields have the
appropriate values.

Creating a Request
data CreateDataSourceFromRedshift Source #

smart constructor.
CreateDataSourceFromRedshift' | |

Instances
newCreateDataSourceFromRedshift Source #
Create a value of CreateDataSourceFromRedshift
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:dataSourceName:CreateDataSourceFromRedshift'
, createDataSourceFromRedshift_dataSourceName
- A user-supplied name or description of the DataSource
.
$sel:computeStatistics:CreateDataSourceFromRedshift'
, createDataSourceFromRedshift_computeStatistics
- The compute statistics for a DataSource
. The statistics are generated
from the observation data referenced by a DataSource
. Amazon ML uses
the statistics internally during MLModel
training. This parameter must
be set to true
if the DataSource
needs to be used for MLModel
training.
$sel:dataSourceId:CreateDataSourceFromRedshift'
, createDataSourceFromRedshift_dataSourceId
- A user-supplied ID that uniquely identifies the DataSource
.
$sel:dataSpec:CreateDataSourceFromRedshift'
, createDataSourceFromRedshift_dataSpec
- The data specification of an Amazon Redshift DataSource
:
DatabaseInformation -
DatabaseName
- The name of the Amazon Redshift database.ClusterIdentifier
- The unique ID for the Amazon Redshift cluster.
- DatabaseCredentials - The AWS Identity and Access Management (IAM) credentials that are used to connect to the Amazon Redshift database.
- SelectSqlQuery - The query that is used to retrieve the observation
data for the
Datasource
. - S3StagingLocation - The Amazon Simple Storage Service (Amazon S3)
location for staging Amazon Redshift data. The data retrieved from
Amazon Redshift using the
SelectSqlQuery
query is stored in this location. - DataSchemaUri - The Amazon S3 location of the
DataSchema
. - DataSchema - A JSON string representing the schema. This is not
required if
DataSchemaUri
is specified. DataRearrangement - A JSON string that represents the splitting and rearrangement requirements for the
DataSource
.Sample -
"{\"splitting\":{\"percentBegin\":10,\"percentEnd\":60}}"
$sel:roleARN:CreateDataSourceFromRedshift'
, createDataSourceFromRedshift_roleARN
- A fully specified role Amazon Resource Name (ARN). Amazon ML assumes the
role on behalf of the user to create the following:
- A security group to allow Amazon ML to execute the
SelectSqlQuery
query on an Amazon Redshift cluster - An Amazon S3 bucket policy to grant Amazon ML read/write
permissions on the
S3StagingLocation

Destructuring the Response
data CreateDataSourceFromRedshiftResponse Source #
Represents the output of a CreateDataSourceFromRedshift
operation, and
is an acknowledgement that Amazon ML received the request.
The CreateDataSourceFromRedshift
operation is asynchronous. You can
poll for updates by using the GetBatchPrediction
operation and
checking the Status
parameter.
