CreateDBCluster

Creates a new Amazon Neptune DB cluster.

You can use the ReplicationSourceIdentifier parameter to create the DB cluster as a Read Replica of another DB cluster or Amazon Neptune DB instance.

Request Parameters

For information about the parameters that are common to all actions, see Common Parameters.

AvailabilityZones.AvailabilityZone.N

A list of EC2 Availability Zones that instances in the DB cluster can be created in.

Type: Array of strings

Required: No

BackupRetentionPeriod

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

Default: 1

Constraints:

Must be a value from 1 to 35

Type: Integer

Required: No

CharacterSetName

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

Type: String

Required: No

DatabaseName

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

Type: String

Required: No

DBClusterIdentifier

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

Constraints:

Must contain from 1 to 63 letters, numbers, or hyphens.
First character must be a letter.
Cannot end with a hyphen or contain two consecutive hyphens.

Example: my-cluster1

Type: String

Required: Yes

DBClusterParameterGroupName

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

Constraints:

If supplied, must match the name of an existing DBClusterParameterGroup.

Type: String

Required: No

DBSubnetGroupName

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

Required: No

EnableIAMDatabaseAuthentication

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

Default: false

Type: Boolean

Required: No

Engine

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

Valid Values: neptune

Type: String

Required: Yes

EngineVersion

The version number of the database engine to use.

Example: 1.0.1

Type: String

Required: No

KmsKeyId

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 Neptune will use the encryption key used to encrypt the source. Otherwise, Amazon Neptune will use your default encryption key.
If the StorageEncrypted parameter is true and ReplicationSourceIdentifier is not specified, then Amazon Neptune 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

Required: No

MasterUsername

The name of the master user for the DB cluster.

Constraints:

Must be 1 to 16 letters or numbers.
First character must be a letter.
Cannot be a reserved word for the chosen database engine.

Type: String

Required: No

MasterUserPassword

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

Required: No

OptionGroupName

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: String

Required: No

Port

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

Default: 8182

Type: Integer

Required: No

PreferredBackupWindow

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 Maintenance Window in the Amazon Neptune User Guide.

Constraints:

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

Required: No

PreferredMaintenanceWindow

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 Maintenance Window in the Amazon Neptune User Guide.

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

Constraints: Minimum 30-minute window.

Type: String

Required: No

PreSignedUrl

This parameter is not currently supported.

Type: String

Required: No

ReplicationSourceIdentifier

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

Type: String

Required: No

StorageEncrypted

Specifies whether the DB cluster is encrypted.

Type: Boolean

Required: No

Tags.Tag.N

A list of tags. For more information, see Tagging Amazon Neptune Resources.

Type: Array of Tag objects

Required: No

VpcSecurityGroupIds.VpcSecurityGroupId.N

A list of EC2 VPC security groups to associate with this DB cluster.

Type: Array of strings

Required: No

Response Elements
