The AWS KMS key identifier for an encrypted cluster.

The AWS KMS key identifier is the Amazon Resource Name (ARN) for the AWS KMS encryption key. If you are creating a cluster using the same AWS account that owns the AWS KMS encryption key that is used to encrypt the new cluster, you can use the AWS KMS key alias instead of the ARN for the AWS KMS encryption key.

If an encryption key is not specified in KmsKeyId :

If the StorageEncrypted parameter is true , Amazon DocumentDB uses 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 Regions .

Constraints: You can't specify copy-on-write if the engine version of the source DB cluster is earlier than 1.11.

If you don't specify a RestoreType value, then the new DB cluster is restored as a full copy of the source DB cluster.

serverlessV2ScalingConfiguration?

Type: IResolvable | ServerlessV2ScalingConfigurationProperty (optional)

snapshotIdentifier?

Type: string (optional)

The identifier for the snapshot or cluster snapshot to restore from.

You can use either the name or the Amazon Resource Name (ARN) to specify a cluster snapshot. However, you can use only the ARN to specify a snapshot.

Constraints:

Must match the identifier of an existing snapshot.

sourceDbClusterIdentifier?

Type: string (optional)

The identifier of the source cluster from which to restore.

Constraints:

Must match the identifier of an existing DBCluster .

storageEncrypted?

Type: boolean | IResolvable (optional)

Specifies whether the cluster is encrypted.

If you specify SourceDBClusterIdentifier or SnapshotIdentifier and don’t specify StorageEncrypted , the encryption property is inherited from the source cluster or snapshot (unless KMSKeyId is specified, in which case the restored cluster will be encrypted with that KMS key). If the source is encrypted and StorageEncrypted is specified to be true, the restored cluster will be encrypted (if you want to use a different KMS key, specify the KMSKeyId property as well). If the source is unencrypted and StorageEncrypted is specified to be true, then the KMSKeyId property must be specified. If the source is encrypted, don’t specify StorageEncrypted to be false as opting out of encryption is not allowed.

addDeletionOverride(path)

public addDeletionOverride(path: string): void

Parameters

path string — The path of the value to delete.

Syntactic sugar for addOverride(path, undefined).

addDependency(target)

public addDependency(target: CfnResource): void

Parameters

target CfnResource

Indicates that this resource depends on another resource and cannot be provisioned unless the other resource has been successfully provisioned.

This can be used for resources across stacks (or nested stack) boundaries and the dependency will automatically be transferred to the relevant scope.

addDependsOn(target)⚠️

public addDependsOn(target: CfnResource): void

⚠️ Deprecated: use addDependency

Parameters

target CfnResource

Indicates that this resource depends on another resource and cannot be provisioned unless the other resource has been successfully provisioned.

addMetadata(key, value)

public addMetadata(key: string, value: any): void

Parameters

key string
value any

Add a value to the CloudFormation Resource Metadata.

Note that this is a different set of metadata from CDK node metadata; this metadata ends up in the stack template under the resource, whereas CDK node metadata ends up in the Cloud Assembly.](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/metadata-section-structure.html

Note that this is a different set of metadata from CDK node metadata; this metadata ends up in the stack template under the resource, whereas CDK node metadata ends up in the Cloud Assembly.)

addOverride(path, value)

public addOverride(path: string, value: any): void

Parameters

path string — - The path of the property, you can use dot notation to override values in complex types.
value any — - The value.

Adds an override to the synthesized CloudFormation resource.

To add a property override, either use addPropertyOverride or prefix path with "Properties." (i.e. Properties.TopicName).

If the override is nested, separate each nested level using a dot (.) in the path parameter. If there is an array as part of the nesting, specify the index in the path.

To include a literal . in the property name, prefix with a \. In most programming languages you will need to write this as "\\." because the \ itself will need to be escaped.

For example,

cfnResource.addOverride('Properties.GlobalSecondaryIndexes.0.Projection.NonKeyAttributes', ['myattribute']);
cfnResource.addOverride('Properties.GlobalSecondaryIndexes.1.ProjectionType', 'INCLUDE');

would add the overrides

"Properties": {
  "GlobalSecondaryIndexes": [
    {
      "Projection": {
        "NonKeyAttributes": [ "myattribute" ]
        ...
      }
      ...
    },
    {
      "ProjectionType": "INCLUDE"
      ...
    },
  ]
  ...
}

The value argument to addOverride will not be processed or translated in any way. Pass raw JSON values in here with the correct capitalization for CloudFormation. If you pass CDK classes or structs, they will be rendered with lowercased key names, and CloudFormation will reject the template.

addPropertyDeletionOverride(propertyPath)

public addPropertyDeletionOverride(propertyPath: string): void

Parameters

propertyPath string — The path to the property.

Adds an override that deletes the value of a property from the resource definition.

addPropertyOverride(propertyPath, value)

public addPropertyOverride(propertyPath: string, value: any): void

Parameters

propertyPath string — The path of the property.
value any — The value.

Adds an override to a resource property.

Syntactic sugar for addOverride("Properties.<...>", value).

applyRemovalPolicy(policy?, options?)

public applyRemovalPolicy(policy?: RemovalPolicy, options?: RemovalPolicyOptions): void

Parameters

policy RemovalPolicy
options RemovalPolicyOptions

Sets the deletion policy of the resource based on the removal policy specified.

The Removal Policy controls what happens to this resource when it stops being managed by CloudFormation, either because you've removed it from the CDK application or because you've made a change that requires the resource to be replaced.

The resource can be deleted (RemovalPolicy.DESTROY), or left in your AWS account for data recovery and cleanup later (RemovalPolicy.RETAIN). In some cases, a snapshot can be taken of the resource prior to deletion (RemovalPolicy.SNAPSHOT). A list of resources that support this policy can be found in the following link:

getAtt(attributeName, typeHint?)

public getAtt(attributeName: string, typeHint?: ResolutionTypeHint): Reference

Parameters

attributeName string — The name of the attribute.
typeHint ResolutionTypeHint

Returns

Reference

Returns a token for an runtime attribute of this resource.

Ideally, use generated attribute accessors (e.g. resource.arn), but this can be used for future compatibility in case there is no generated attribute.

getMetadata(key)

public getMetadata(key: string): any

Parameters

key string

Returns

any

Retrieve a value value from the CloudFormation Resource Metadata.

Note that this is a different set of metadata from CDK node metadata; this metadata ends up in the stack template under the resource, whereas CDK node metadata ends up in the Cloud Assembly.)

inspect(inspector)

public inspect(inspector: TreeInspector): void

Parameters

inspector TreeInspector — tree inspector to collect and process attributes.

Examines the CloudFormation resource and discloses attributes.

obtainDependencies()

public obtainDependencies(): Stack &#124; CfnResource[]

Returns

Stack | CfnResource[]

Retrieves an array of resources this resource depends on.

This assembles dependencies on resources across stacks (including nested stacks) automatically.

obtainResourceDependencies()

public obtainResourceDependencies(): CfnResource[]

Returns

CfnResource[]

Get a shallow copy of dependencies between this resource and other resources in the same stack.

overrideLogicalId(newLogicalId)

public overrideLogicalId(newLogicalId: string): void

Overrides the auto-generated logical ID with a specific ID.

removeDependency(target)

public removeDependency(target: CfnResource): void

Parameters

target CfnResource

Indicates that this resource no longer depends on another resource.

This can be used for resources across stacks (including nested stacks) and the dependency will automatically be removed from the relevant scope.

public replaceDependency(target: CfnResource, newTarget: CfnResource): void

Parameters

target CfnResource — The dependency to replace.
newTarget CfnResource — The new dependency to add.
