---

clusterArn

Type: string

The ARN of the cluster.

---

clusterEndpoint

Type: Endpoint

The endpoint to use for read/write operations.

---

clusterIdentifier

Type: string

Identifier of the cluster.

---

clusterReadEndpoint

Type: Endpoint

Endpoint to use for load-balanced read-only operations.

---

clusterResourceIdentifier

Type: string

The immutable identifier for the cluster; for example: cluster-ABCD1234EFGH5678IJKL90MNOP.

This AWS Region-unique identifier is used in things like IAM authentication policies.

---

connections

Type: Connections

Access to the network connections.

---

env

Type: ResourceEnvironment

The environment this resource belongs to.

For resources that are created and managed by the CDK (generally, those created by creating new class instances like Role, Bucket, etc.), this is always the same as the environment of the stack they belong to; however, for imported resources (those obtained from static methods like fromRoleArn, fromBucketName, etc.), that might be different than the stack they were imported into.

---

instanceEndpoints

Type: Endpoint[]

Endpoints which address each individual replica.

---

instanceIdentifiers

Type: string[]

Identifiers of the replicas.

---

node

Type: Node

The tree node.

---

stack

Type: Stack

The stack in which this resource is defined.

---

enableDataApi?

Type: boolean (optional)

---

engine?

Type: IClusterEngine (optional)

The engine of this Cluster.

May be not known for imported Clusters if it wasn't provided explicitly.

---

secret?

Type: ISecret (optional)

The secret attached to this cluster.

addProxy(id, options)

public addProxy(id: string, options: DatabaseProxyOptions): DatabaseProxy

Parameters

• id string
• options DatabaseProxyOptions

Returns

• DatabaseProxy

Add a new db proxy to this cluster.

---

applyRemovalPolicy(policy)

public applyRemovalPolicy(policy: RemovalPolicy): void

Parameters

• policy RemovalPolicy

Apply the given removal policy to this resource.

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).
