Amazon Neptune Construct Library

This module is part of the AWS Cloud Development Kit project.

import neptune "github.com/aws/aws-cdk-go/awscdk"

There are no official hand-written (L2) constructs for this service yet. Here are some suggestions on how to proceed:

An experimental construct library for this service is available in preview. Since it is not stable yet, it is distributed as a separate package so that you can pin its version independently of the rest of the CDK. See the package:

@aws-cdk/aws-neptune-alpha

There are no hand-written (L2) constructs for this service yet. However, you can still use the automatically generated L1 constructs, and use this service exactly as you would using CloudFormation directly.

For more information on the resources and properties available for this service, see the CloudFormation documentation for AWS::Neptune.

(Read the CDK Contributing Guide and submit an RFC if you are interested in contributing to this construct library.)

Functions

func CfnDBClusterParameterGroup_CFN_RESOURCE_TYPE_NAME 

func CfnDBClusterParameterGroup_CFN_RESOURCE_TYPE_NAME() *string

func CfnDBClusterParameterGroup_IsCfnElement 

func CfnDBClusterParameterGroup_IsCfnElement(x interface{}) *bool

Returns `true` if a construct is a stack element (i.e. part of the synthesized cloudformation template).

Uses duck-typing instead of `instanceof` to allow stack elements from different versions of this library to be included in the same stack.

Returns: The construct as a stack element or undefined if it is not a stack element.

func CfnDBClusterParameterGroup_IsCfnResource 

func CfnDBClusterParameterGroup_IsCfnResource(construct constructs.IConstruct) *bool

Check whether the given construct is a CfnResource.

func CfnDBClusterParameterGroup_IsConstruct 

func CfnDBClusterParameterGroup_IsConstruct(x interface{}) *bool

Checks if `x` is a construct.

Use this method instead of `instanceof` to properly detect `Construct` instances, even when the construct library is symlinked.

Explanation: in JavaScript, multiple copies of the `constructs` library on disk are seen as independent, completely different libraries. As a consequence, the class `Construct` in each copy of the `constructs` library is seen as a different class, and an instance of one class will not test as `instanceof` the other class. `npm install` will not create installations like this, but users may manually symlink construct libraries together or use a monorepo tool: in those cases, multiple copies of the `constructs` library can be accidentally installed, and `instanceof` will behave unpredictably. It is safest to avoid using `instanceof`, and using this type-testing method instead.

Returns: true if `x` is an object created from a class which extends `Construct`.

A CloudFormation `AWS::Neptune::DBCluster`.

The `AWS::Neptune::DBCluster` resource creates an Amazon Neptune DB cluster. Neptune is a fully managed graph database.

> Currently, you can create this resource only in AWS Regions in which Amazon Neptune is supported.

If no `DeletionPolicy` is set for `AWS::Neptune::DBCluster` resources, the default deletion behavior is that the entire volume will be deleted without a snapshot. To retain a backup of the volume, the `DeletionPolicy` should be set to `Snapshot` . For more information about how AWS CloudFormation deletes resources, see [DeletionPolicy Attribute](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-attribute-deletionpolicy.html) .

You can use `AWS::Neptune::DBCluster.DeletionProtection` to help guard against unintended deletion of your DB cluster.

Example: 

// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.

A CloudFormation `AWS::Neptune::DBInstance`.

The `AWS::Neptune::DBInstance` type creates an Amazon Neptune DB instance.

*Updating DB Instances*

You can set a deletion policy for your DB instance to control how AWS CloudFormation handles the instance when the stack is deleted. For Neptune DB instances, you can choose to *retain* the instance, to *delete* the instance, or to *create a snapshot* of the instance. The default AWS CloudFormation behavior depends on the `DBClusterIdentifier` property:

- For `AWS::Neptune::DBInstance` resources that don't specify the `DBClusterIdentifier` property, AWS CloudFormation saves a snapshot of the DB instance. - For `AWS::Neptune::DBInstance` resources that do specify the `DBClusterIdentifier` property, AWS CloudFormation deletes the DB instance.

*Deleting DB Instances*

> If a DB instance is deleted or replaced during an update, AWS CloudFormation deletes all automated snapshots. However, it retains manual DB snapshots. During an update that requires replacement, you can apply a stack policy to prevent DB instances from being replaced.

When properties labeled *Update requires: Replacement* are updated, AWS CloudFormation first creates a replacement DB instance, changes references from other dependent resources to point to the replacement DB instance, and finally deletes the old DB instance.

> We highly recommend that you take a snapshot of the database before updating the stack. If you don't, you lose the data when AWS CloudFormation replaces your DB instance. To preserve your data, perform the following procedure: > > - Deactivate any applications that are using the DB instance so that there's no activity on the DB instance. > - Create a snapshot of the DB instance. > - If you want to restore your instance using a DB snapshot, modify the updated template with your DB instance changes and add the `DBSnapshotIdentifier` property with the ID of the DB snapshot that you want to use. > - Update the stack.

A CloudFormation `AWS::Neptune::DBParameterGroup`.

`AWS::Neptune::DBParameterGroup` creates a new DB parameter group. This type can be declared in a template and referenced in the `DBParameterGroupName` parameter of `AWS::Neptune::DBInstance` .

> Applying a parameter group to a DB instance might require the instance to reboot, resulting in a database outage for the duration of the reboot.

A DB parameter group is initially created with the default parameters for the database engine used by the DB instance. To provide custom values for any of the parameters, you must modify the group after creating it using *ModifyDBParameterGroup* . Once you've created a DB parameter group, you need to associate it with your DB instance using *ModifyDBInstance* . When you associate a new DB parameter group with a running DB instance, you need to reboot the DB instance without failover for the new DB parameter group and associated settings to take effect.

> After you create a DB parameter group, you should wait at least 5 minutes before creating your first DB instance that uses that DB parameter group as the default parameter group. This allows Amazon Neptune to fully complete the create action before the parameter group is used as the default for a new DB instance. This is especially important for parameters that are critical when creating the default database for a DB instance, such as the character set for the default database defined by the `character_set_database` parameter. You can use the *Parameter Groups* option of the Amazon Neptune console or the *DescribeDBParameters* command to verify that your DB parameter group has been created or modified.

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

	// "Properties": {
	//    "GlobalSecondaryIndexes": [
	//      {
	//        "Projection": {
	//          "NonKeyAttributes": [ "myattribute" ]

A CloudFormation `AWS::Neptune::DBSubnetGroup`.

The `AWS::Neptune::DBSubnetGroup` type creates an Amazon Neptune DB subnet group. Subnet groups must contain at least two subnets in two different Availability Zones in the same AWS Region.

Example: 

// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import "github.com/aws/aws-cdk-go/awscdk"

cfnDBSubnetGroup := awscdk.Aws_neptune.NewCfnDBSubnetGroup(this, jsii.String("MyCfnDBSubnetGroup"), &CfnDBSubnetGroupProps{
	DbSubnetGroupDescription: jsii.String("dbSubnetGroupDescription"),
	SubnetIds: []*string{
		jsii.String("subnetIds"),
	},

	// the properties below are optional
	DbSubnetGroupName: jsii.String("dbSubnetGroupName"),
	Tags: []cfnTag{
		&cfnTag{
			Key: jsii.String("key"),
			Value: jsii.String("value"),
		},
	},
})
