Amazon Neptune Construct Library

Amazon Neptune is a fast, reliable, fully managed graph database service that makes it easy to build and run applications that work with highly connected datasets. The core of Neptune is a purpose-built, high-performance graph database engine. This engine is optimized for storing billions of relationships and querying the graph with milliseconds latency. Neptune supports the popular graph query languages Apache TinkerPop Gremlin and W3C’s SPARQL, enabling you to build queries that efficiently navigate highly connected datasets.

The @aws-cdk/aws-neptune package contains primitives for setting up Neptune database clusters and instances.

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

Starting a Neptune Database

To set up a Neptune database, define a DatabaseCluster. You must always launch a database in a VPC.

cluster := neptune.NewDatabaseCluster(this, jsii.String("Database"), &databaseClusterProps{
	vpc: vpc,
	instanceType: neptune.instanceType_R5_LARGE(),
})

By default only writer instance is provisioned with this construct.

Connecting

To control who can access the cluster, use the .connections attribute. Neptune databases have a default port, so you don't need to specify the port:

cluster.connections.allowDefaultPortFromAnyIpv4(jsii.String("Open to the world"))

The endpoints to access your database cluster will be available as the .clusterEndpoint and .clusterReadEndpoint attributes:

writeAddress := cluster.clusterEndpoint.socketAddress

IAM Authentication

You can also authenticate to a database cluster using AWS Identity and Access Management (IAM) database authentication; See https://docs.aws.amazon.com/neptune/latest/userguide/iam-auth.html for more information and a list of supported versions and limitations.

The following example shows enabling IAM authentication for a database cluster and granting connection access to an IAM role.

cluster := neptune.NewDatabaseCluster(this, jsii.String("Cluster"), &databaseClusterProps{
	vpc: vpc,
	instanceType: neptune.instanceType_R5_LARGE(),
	iamAuthentication: jsii.Boolean(true),
})
role := iam.NewRole(this, jsii.String("DBRole"), &roleProps{
	assumedBy: iam.NewAccountPrincipal(this.account),
})
cluster.grantConnect(role)

Customizing parameters

Neptune allows configuring database behavior by supplying custom parameter groups. For more details, refer to the following link: https://docs.aws.amazon.com/neptune/latest/userguide/parameters.html

clusterParams := neptune.NewClusterParameterGroup(this, jsii.String("ClusterParams"), &clusterParameterGroupProps{
	description: jsii.String("Cluster parameter group"),
	parameters: map[string]*string{
		"neptune_enable_audit_log": jsii.String("1"),
	},
})

dbParams := neptune.NewParameterGroup(this, jsii.String("DbParams"), &parameterGroupProps{
	description: jsii.String("Db parameter group"),
	parameters: map[string]*string{
		"neptune_query_timeout": jsii.String("120000"),
	},
})

cluster := neptune.NewDatabaseCluster(this, jsii.String("Database"), &databaseClusterProps{
	vpc: vpc,
	instanceType: neptune.instanceType_R5_LARGE(),
	clusterParameterGroup: clusterParams,
	parameterGroup: dbParams,
})

Adding replicas

DatabaseCluster allows launching replicas along with the writer instance. This can be specified using the instanceCount attribute.

cluster := neptune.NewDatabaseCluster(this, jsii.String("Database"), &databaseClusterProps{
	vpc: vpc,
	instanceType: neptune.instanceType_R5_LARGE(),
	instances: jsii.Number(2),
})

Additionally it is also possible to add replicas using DatabaseInstance for an existing cluster.

replica1 := neptune.NewDatabaseInstance(this, jsii.String("Instance"), &databaseInstanceProps{
	cluster: cluster,
	instanceType: neptune.*instanceType_R5_LARGE(),
})

Automatic minor version upgrades

By setting autoMinorVersionUpgrade to true, Neptune will automatically update the engine of the entire cluster to the latest minor version after a stabilization window of 2 to 3 weeks.

neptune.NewDatabaseCluster(this, jsii.String("Cluster"), &databaseClusterProps{
	vpc: vpc,
	instanceType: neptune.instanceType_R5_LARGE(),
	autoMinorVersionUpgrade: jsii.Boolean(true),
})

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.

// 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.

Example: 

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