Objective-C

@interface AWSMachineLearningCreateDataSourceFromRedshiftInput

Swift

class AWSMachineLearningCreateDataSourceFromRedshiftInput

  • 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.

    Declaration

    Objective-C

    @property (nonatomic, strong) NSNumber *_Nullable computeStatistics;

    Swift

    var computeStatistics: NSNumber? { get set }

  • A user-supplied ID that uniquely identifies the DataSource.

    Declaration

    Objective-C

    @property (nonatomic, strong) NSString *_Nullable dataSourceId;

    Swift

    var dataSourceId: String? { get set }

  • A user-supplied name or description of the DataSource.

    Declaration

    Objective-C

    @property (nonatomic, strong) NSString *_Nullable dataSourceName;

    Swift

    var dataSourceName: String? { get set }

  • 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}}"

    Swift

    var dataSpec: AWSMachineLearningRedshiftDataSpec? { get set }

  • 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

    Declaration

    Objective-C

    @property (nonatomic, strong) NSString *_Nullable roleARN;

    Swift

    var roleARN: String? { get set }
