Using aws glue with neptune

Question

Pulumi · Accepted Answer

AWS Glue is a fully managed extract, transform, and load (ETL) service that makes it easy for customers to prepare and load their data for analytics. 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. Using AWS Glue with Amazon Neptune enables you to create and run an ETL job to prepare data for graph queries.

In the following program written in TypeScript, we will integrate AWS Glue and Amazon Neptune by setting up the necessary resources using Pulumi, which include creating a Neptune cluster and setting up a Glue connection. We'll be leveraging the aws.glue.Connection and aws.neptune.ClusterInstance resources, ensuring that Glue can connect to Neptune properly.

import * as pulumi from "@pulumi/pulumi";
import * as aws from "@pulumi/aws";

// Create a new Neptune cluster
const neptuneCluster = new aws.neptune.Cluster("myNeptuneCluster", {
    engine: "neptune",
    skipFinalSnapshot: true,
});

// Define parameters for the Neptune cluster instance
const neptuneClusterInstance = new aws.neptune.ClusterInstance("myNeptuneClusterInstance", {
    clusterIdentifier: neptuneCluster.id,
    engine: "neptune",
    instanceClass: "db.r5.large",
});

// Retrieve the default security group to use with Glue Connection
const defaultSecurityGroup = aws.ec2.getSecurityGroup({
    name: "default",
});

// Create a new AWS Glue connection to the Neptune cluster
const glueConnection = new aws.glue.Connection("myGlueConnection", {
    connectionProperties: {
        JDBC_CONNECTION_URL: pulumi.interpolate`jdbc:neptune://${neptuneClusterInstance.endpoint}`,
        USERNAME: "<your-neptune-username>",
        PASSWORD: "<your-neptune-password>",
    },
    physicalConnectionRequirements: {
        availabilityZone: neptuneClusterInstance.availabilityZone,
        securityGroupIdList: [defaultSecurityGroup.then(sg => sg.id)],
        subnetId: "<your-subnet-id>", // Replace with your actual subnet ID
    }
});

// Export relevant endpoints
export const neptuneEndpoint = neptuneClusterInstance.endpoint;
export const glueConnectionName = glueConnection.name;

Here's a brief explanation of the code above:

We import the necessary Pulumi and AWS SDK modules.
We create a Neptune cluster by instantiating aws.neptune.Cluster. This will serve as our graph database server.
Next, we create an instance of the Neptune cluster using aws.neptune.ClusterInstance. This is where the Neptune database will run.
We retrieve the default security group for our VPC, which is necessary to set up access to the Neptune cluster from the Glue service.
Finally, we set up a Glue connection using aws.glue.Connection, which defines the necessary properties to connect to our Neptune cluster instance.

Please replace placeholders like <your-neptune-username>, <your-neptune-password>, and <your-subnet-id> with your actual configuration details.

This program is a starting point for integrating AWS Glue with Amazon Neptune. From here, you can define additional resources to create ETL jobs in AWS Glue that interact with your Neptune database. Ensure that your AWS environment permissions are set up correctly to create these resources, and replace any placeholders with actual values before running the program with Pulumi CLI.
