disassociate_dataset_kms_key¶

CloudWatch.Client.disassociate_dataset_kms_key(**kwargs)¶

Removes the customer managed Amazon Web Services Key Management Service (Amazon Web Services KMS) key association from the specified dataset. After this operation completes, data that you publish to the dataset is encrypted at rest using an Amazon Web Services owned key managed by Amazon CloudWatch.

Only the default dataset is supported. To call this operation, the dataset must currently have a customer managed KMS key associated with it. If the dataset has no associated KMS key, the operation fails with ResourceNotFoundException.

Amazon CloudWatch performs a dry-run kms:Decrypt call on the key as part of this operation. This verifies that the caller is authorized to use the currently associated key. The caller must have kms:Decrypt permission on the currently associated key, and the key must be enabled and accessible. If the key has been disabled or scheduled for deletion, you must first re-enable or restore it before you can disassociate it from the dataset.

Warning

Disassociating a KMS key from a dataset does not immediately remove the kms:Decrypt requirement on data plane operations. For up to three hours after disassociation, callers must continue to have kms:Decrypt permission on the previously associated key. Some data may still be encrypted with that key during this window. After this enforcement window elapses, the kms:Decrypt requirement is lifted.

For more information about using customer managed keys with Amazon CloudWatch, see Encryption at rest with customer managed keys in the Amazon CloudWatch User Guide.
