 @option options [String] :replication_source_identifier
   The Amazon Resource Name (ARN) of the source DB instance or DB cluster
   if this DB cluster is created as a Read Replica.
 @option options [Array<Types::Tag>] :tags
   A list of tags. For more information, see [Tagging Amazon RDS
   Resources][1] in the *Amazon RDS User Guide.*



   [1]: https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/USER_Tagging.html
 @option options [Boolean] :storage_encrypted
   Specifies whether the DB cluster is encrypted.
 @option options [String] :kms_key_id
   The AWS KMS key identifier for an encrypted DB cluster.

   The KMS key identifier is the Amazon Resource Name (ARN) for the KMS
   encryption key. If you are creating a DB cluster with the same AWS
   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 an encryption key is not specified in `KmsKeyId`\:

   * If `ReplicationSourceIdentifier` identifies an encrypted source,
     then Amazon RDS will use the encryption key used to encrypt the
     source. Otherwise, Amazon RDS will use your default encryption key.

   * If the `StorageEncrypted` parameter is true and
     `ReplicationSourceIdentifier` is not specified, then Amazon RDS will
     use your default encryption key.

   AWS KMS creates the default encryption key for your AWS account. Your
   AWS account has a different default encryption key for each AWS
   Region.

   If you create a Read Replica of an encrypted DB cluster in another AWS
   Region, you must set `KmsKeyId` to a KMS key ID that is valid in the
   destination AWS Region. This key is used to encrypt the Read Replica
   in that AWS Region.
 @option options [String] :pre_signed_url
   A URL that contains a Signature Version 4 signed request for the
   `CreateDBCluster` action to be called in the source AWS Region where
   the DB cluster is replicated from. You only need to specify
   `PreSignedUrl` when you are performing cross-region replication from
   an encrypted DB cluster.

   The pre-signed URL must be a valid request for the `CreateDBCluster`
   API action that can be executed in the source AWS Region that contains
   the encrypted DB cluster to be copied.

   The pre-signed URL request must contain the following parameter
   values:

   * `KmsKeyId` - The AWS KMS key identifier for the key to use to
     encrypt the copy of the DB cluster in the destination AWS Region.
     This should refer to the same KMS key for both the `CreateDBCluster`
     action that is called in the destination AWS Region, and the action
     contained in the pre-signed URL.

   * `DestinationRegion` - The name of the AWS Region that Aurora Read
     Replica will be created in.

   * `ReplicationSourceIdentifier` - The DB cluster identifier for the
     encrypted DB cluster to be copied. This identifier must be in the
     Amazon Resource Name (ARN) format for the source AWS Region. For
     example, if you are copying an encrypted DB cluster from the
     us-west-2 AWS Region, then your `ReplicationSourceIdentifier` would
     look like Example:
     `arn:aws:rds:us-west-2:123456789012:cluster:aurora-cluster1`.

   To learn how to generate a Signature Version 4 signed request, see [
   Authenticating Requests: Using Query Parameters (AWS Signature Version
   4)][1] and [ Signature Version 4 Signing Process][2].

 @option options [Boolean] :enable_iam_database_authentication
   True to enable mapping of AWS Identity and Access Management (IAM)
   accounts to database accounts, and otherwise false.

   Default: `false`
 @option options [Integer] :backtrack_window
   The target backtrack window, in seconds. To disable backtracking, set
   this value to 0.

   Default: 0

   Constraints:

   * If specified, this value must be set to a number from 0 to 259,200
     (72 hours).

   ^
 @option options [Array<String>] :enable_cloudwatch_logs_exports
   The list of log types that need to be enabled for exporting to
   CloudWatch Logs. The values in the list depend on the DB engine being
   used. For more information, see [Publishing Database Logs to Amazon
   CloudWatch Logs][1] in the *Amazon Aurora User Guide*.

   For DB clusters in `serverless` DB engine mode, the scaling properties
   of the DB cluster.
 @option options [Boolean] :deletion_protection
   Indicates if the DB cluster should have deletion protection enabled.
   The database can't be deleted when this value is set to true. The
   default is false.
 @option options [String] :global_cluster_identifier
   The global cluster ID of an Aurora cluster that becomes the primary
   cluster in the new global database cluster.
 @option options [Boolean] :copy_tags_to_snapshot
   True to copy all tags from the DB cluster to snapshots of the DB
   cluster, and otherwise false. The default is false.
 @option options [String] :destination_region
 @option options [String] :source_region
   The source region of the snapshot. This is only needed when the
   shapshot is encrypted and in a different region.
