-- Creates a new DB cluster from a DB cluster snapshot. The target DB
-- cluster is created from the source DB cluster restore point with the
-- same configuration as the original source DB cluster, except that the
-- new DB cluster is created with the default security group.

--
-- The KMS key identifier is the Amazon Resource Name (ARN) for the KMS

-- account that owns the KMS encryption key used to encrypt the new DB
-- cluster, then you can use the KMS key alias instead of the ARN for the
-- KMS encryption key.
--
-- If you do not specify a value for the 'KmsKeyId' parameter, then the
-- following will occur:
--
-- -   If the DB cluster snapshot is encrypted, then the restored DB
--     cluster is encrypted using the KMS key that was used to encrypt the
--     DB cluster snapshot.
-- -   If the DB cluster snapshot is not encrypted, then the restored DB
--     cluster is not encrypted.
--
-- If 'SnapshotIdentifier' refers to a DB cluster snapshot that is not
-- encrypted, and you specify a value for the 'KmsKeyId' parameter, then
-- the restore request is rejected.
