Type: []*string

A list of EC2 Availability Zones that instances in the DB cluster can be created in. For information on AWS Regions and Availability Zones, see Choosing the Regions and Availability Zones ( in the Amazon Aurora User Guide.


Type: *int64

The target backtrack window, in seconds. To disable backtracking, set this value to 0.

Default: 0


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


Type: *int64

The number of days for which automated backups are retained. You must specify a minimum value of 1.

Default: 1


  • Must be a value from 1 to 35


Type: *string

A value that indicates that the DB cluster should be associated with the specified CharacterSet.


Type: *string

The DB cluster identifier. This parameter is stored as a lowercase string.


  • Must contain from 1 to 63 letters, numbers, or hyphens.

  • First character must be a letter.

  • Can't end with a hyphen or contain two consecutive hyphens.

Example: my-cluster1

DBClusterIdentifier is a required field


Type: *string

The name of the DB cluster parameter group to associate with this DB cluster. If this argument is omitted, default.aurora5.6 is used.


  • If supplied, must match the name of an existing DB cluster parameter group.


Type: *string

A DB subnet group to associate with this DB cluster.

Constraints: Must match the name of an existing DBSubnetGroup. Must not be default.

Example: mySubnetgroup


Type: *string

The name for your database of up to 64 alpha-numeric characters. If you do not provide a name, Amazon RDS will not create a database in the DB cluster you are creating.


Type: *bool

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.


Type: *string

DestinationRegion is used for presigning the request to a given region.


Type: []*string

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 ( in the Amazon Aurora User Guide.


Type: *bool

True to enable mapping of AWS Identity and Access Management (IAM) accounts to database accounts, and otherwise false.

Default: false


Type: *string

The name of the database engine to be used for this DB cluster.

Valid Values: aurora (for MySQL 5.6-compatible Aurora), aurora-mysql (for MySQL 5.7-compatible Aurora), and aurora-postgresql

Engine is a required field


Type: *string

The DB engine mode of the DB cluster, either provisioned, serverless, parallelquery, or global.


Type: *string

The version number of the database engine to use.

Aurora MySQL

Example: 5.6.10a, 5.7.12

Aurora PostgreSQL

Example: 9.6.3


Type: *string

The global cluster ID of an Aurora cluster that becomes the primary cluster in the new global database cluster.


Type: *string

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.


Type: *string

The password for the master database user. This password can contain any printable ASCII character except "/", """, or "@".

Constraints: Must contain from 8 to 41 characters.


Type: *string

The name of the master user for the DB cluster.


  • Must be 1 to 16 letters or numbers.

  • First character must be a letter.

  • Can't be a reserved word for the chosen database engine.


Type: *string

A value that indicates that the DB cluster should be associated with the specified option group.

Permanent options can't be removed from an option group. The option group can't be removed from a DB cluster once it is associated with a DB cluster.


Type: *int64

The port number on which the instances in the DB cluster accept connections.

Default: 3306 if engine is set as aurora or 5432 if set to aurora-postgresql.


Type: *string

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) ( and Signature Version 4 Signing Process (


Type: *string

The daily time range during which automated backups are created if automated backups are enabled using the BackupRetentionPeriod parameter.

The default is a 30-minute window selected at random from an 8-hour block of time for each AWS Region. To see the time blocks available, see Adjusting the Preferred DB Cluster Maintenance Window ( in the Amazon Aurora User Guide.


  • Must be in the format hh24:mi-hh24:mi.

  • Must be in Universal Coordinated Time (UTC).

  • Must not conflict with the preferred maintenance window.

  • Must be at least 30 minutes.


Type: *string

The weekly time range during which system maintenance can occur, in Universal Coordinated Time (UTC).

Format: ddd:hh24:mi-ddd:hh24:mi

The default is a 30-minute window selected at random from an 8-hour block of time for each AWS Region, occurring on a random day of the week. To see the time blocks available, see Adjusting the Preferred DB Cluster Maintenance Window ( in the Amazon Aurora User Guide.

Valid Days: Mon, Tue, Wed, Thu, Fri, Sat, Sun.

Constraints: Minimum 30-minute window.


Type: *string

The Amazon Resource Name (ARN) of the source DB instance or DB cluster if this DB cluster is created as a Read Replica.


Contains the scaling configuration of an Aurora Serverless DB cluster.

For more information, see Using Amazon Aurora Serverless ( in the Amazon Aurora User Guide.


Type: *string

SourceRegion is the source region where the resource exists. This is not sent over the wire and is only used for presigning. This value should always have the same region as the source ARN.


Type: *bool

Specifies whether the DB cluster is encrypted.
