getDataset
Returns information about the specified dataset. This includes its identifier, Amazon Resource Name (ARN), and any customer managed Amazon Web Services Key Management Service (Amazon Web Services KMS) key that is currently associated with it.
Only the default dataset is supported. The default dataset is implicit for every account in every Region — you can call GetDataset for it without first creating it. If no customer managed KMS key has been associated with the dataset, the response omits the KmsKeyArn field, indicating that data is encrypted at rest using an Amazon Web Services owned key managed by Amazon CloudWatch.
To associate a customer managed KMS key with a dataset, use AssociateDatasetKmsKey. To remove the association, use DisassociateDatasetKmsKey.
