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.
