// 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.
