DataSource from Amazon
Redshift. 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 status can only be used to perform
CreateMLModel, CreateEvaluation, or CreateBatchPrediction operations.
If Amazon ML cannot 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 exist in the database hosted on an Amazon Redshift cluster
and should be specified by a SelectSqlQuery. Amazon ML executes
Unload command in Amazon Redshift to transfer the result set of SelectSqlQuery
to S3StagingLocation.
After the DataSource is created, it's ready for use in evaluations and
batch predictions. If you plan to use the DataSource to train an MLModel,
the DataSource requires another item -- a recipe. A recipe describes
the observation variables that participate in training an MLModel. A
recipe describes how each input variable will be used in training. Will the variable
be included or excluded from training? Will the variable be manipulated, for example,
combined with another variable or split apart into word combinations? The recipe provides
answers to these questions. For more information, see the Amazon Machine Learning
Developer Guide.
