Construct Props

NameTypeDescription
clusterIDatabaseClusterThe DocumentDB database cluster the instance should launch into.
instanceTypeInstanceTypeThe name of the compute and memory capacity classes.
autoMinorVersionUpgrade?booleanIndicates that minor engine upgrades are applied automatically to the DB instance during the maintenance window.
availabilityZone?stringThe name of the Availability Zone where the DB instance will be located.
dbInstanceName?stringA name for the DB instance.
enablePerformanceInsights?booleanA value that indicates whether to enable Performance Insights for the DB Instance.
preferredMaintenanceWindow?stringThe weekly time range (in UTC) during which system maintenance can occur.

cluster

Type: IDatabaseCluster

The DocumentDB database cluster the instance should launch into.


instanceType

Type: InstanceType

The name of the compute and memory capacity classes.


autoMinorVersionUpgrade?

Type: boolean (optional, default: true)

Indicates that minor engine upgrades are applied automatically to the DB instance during the maintenance window.


availabilityZone?

Type: string (optional, default: no preference)

The name of the Availability Zone where the DB instance will be located.


dbInstanceName?

Type: string (optional, default: a CloudFormation generated name)

A name for the DB instance.

If you specify a name, AWS CloudFormation converts it to lowercase.


enablePerformanceInsights?

Type: boolean (optional, default: false)

A value that indicates whether to enable Performance Insights for the DB Instance.


preferredMaintenanceWindow?

Type: string (optional, default: 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 https://docs.aws.amazon.com/documentdb/latest/developerguide/db-instance-maintain.html#maintenance-window)

The weekly time range (in UTC) during which system maintenance can occur.

Format: ddd:hh24:mi-ddd:hh24:mi Constraint: Minimum 30-minute window


removalPolicy?

Type: RemovalPolicy (optional, default: RemovalPolicy.Retain)

The CloudFormation policy to apply when the instance is removed from the stack or replaced during an update.

Properties

NameTypeDescription
clusterIDatabaseClusterThe instance's database cluster.
dbInstanceEndpointAddressstringThe instance endpoint address.
dbInstanceEndpointPortstringThe instance endpoint port.
envResourceEnvironmentThe environment this resource belongs to.
instanceArnstringThe instance arn.
instanceEndpointEndpointThe instance endpoint.
instanceIdentifierstringThe instance identifier.
nodeNodeThe tree node.
stackStackThe stack in which this resource is defined.

cluster

Type: IDatabaseCluster

The instance's database cluster.


dbInstanceEndpointAddress

Type: string

The instance endpoint address.


dbInstanceEndpointPort

Type: string

The instance endpoint port.


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.


instanceArn

Type: string

The instance arn.


instanceEndpoint

Type: Endpoint

The instance endpoint.


instanceIdentifier

Type: string

The instance identifier.


node

Type: Node

The tree node.


stack

Type: Stack

The stack in which this resource is defined.

Methods

NameDescription
applyRemovalPolicy(policy)Apply the given removal policy to this resource.
toString()Returns a string representation of this construct.
static fromDatabaseInstanceAttributes(scope, id, attrs)Import an existing database instance.

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).


toString()

public toString(): string

Returns

  • string

Returns a string representation of this construct.


static fromDatabaseInstanceAttributes(scope, id, attrs)

public static fromDatabaseInstanceAttributes(scope: Construct, id: string, attrs: DatabaseInstanceAttributes): IDatabaseInstance

Parameters

  • scope Construct
  • id string
  • attrs DatabaseInstanceAttributes

Returns

  • IDatabaseInstance

Import an existing database instance.
