createDataset method
- required List<
DatasetAction> actions, - required String datasetName,
- List<
DatasetContentDeliveryRule> ? contentDeliveryRules, - List<
LateDataRule> ? lateDataRules, - RetentionPeriod? retentionPeriod,
- List<
Tag> ? tags, - List<
DatasetTrigger> ? triggers, - VersioningConfiguration? versioningConfiguration,
Creates a dataset. A dataset stores data retrieved from a data store by
applying a queryAction
(a SQL query) or a
containerAction
(executing a containerized application). This
operation creates the skeleton of a dataset. The dataset can be populated
manually by calling CreateDatasetContent
or automatically
according to a trigger you specify.
May throw InvalidRequestException. May throw ResourceAlreadyExistsException. May throw InternalFailureException. May throw ServiceUnavailableException. May throw ThrottlingException. May throw LimitExceededException.
Parameter actions
:
A list of actions that create the data set contents.
Parameter datasetName
:
The name of the data set.
Parameter contentDeliveryRules
:
When dataset contents are created, they are delivered to destinations
specified here.
Parameter lateDataRules
:
A list of data rules that send notifications to Amazon CloudWatch, when
data arrives late. To specify lateDataRules
, the dataset must
use a DeltaTimer
filter.
Parameter retentionPeriod
:
Optional. How long, in days, versions of dataset contents are kept for the
dataset. If not specified or set to null
, versions of dataset
contents are retained for at most 90 days. The number of versions of
dataset contents retained is determined by the
versioningConfiguration
parameter. For more information, see
Keeping
Multiple Versions of AWS IoT Analytics Data Sets in the AWS IoT
Analytics User Guide.
Parameter tags
:
Metadata which can be used to manage the data set.
Parameter triggers
:
A list of triggers. A trigger causes data set contents to be populated at
a specified time interval or when another data set's contents are created.
The list of triggers can be empty or contain up to five
DataSetTrigger
objects.
Parameter versioningConfiguration
:
Optional. How many versions of dataset contents are kept. If not specified
or set to null, only the latest version plus the latest succeeded version
(if they are different) are kept for the time period specified by the
retentionPeriod
parameter. For more information, see Keeping
Multiple Versions of AWS IoT Analytics Data Sets in the AWS IoT
Analytics User Guide.
