Data Sharing Among Redshift Clusters With Cross-Database Queries

Introduction

In this guide, we will demonstrate how to set up data sharing among Amazon Redshift clusters using cross-database queries. This involves creating a Redshift cluster, configuring data sharing, and setting up the necessary permissions. The key services involved are Amazon Redshift and AWS Identity and Access Management (IAM).

Step-by-Step Explanation

Step 1: Create a Redshift Cluster

First, we need to create a Redshift cluster. This can be done using Pulumi’s AWS SDK.

Step 2: Configure Data Sharing

Next, we will configure data sharing between the Redshift clusters. This involves creating a datashare and associating it with the producer and consumer clusters.

Step 3: Set Up Permissions

Finally, we will set up the necessary IAM roles and policies to allow cross-database queries.

Conclusion

By following these steps, you can set up data sharing among Amazon Redshift clusters using cross-database queries. This allows you to efficiently share data between clusters without the need for data duplication.

Full Code Example

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

// Create an IAM role for Redshift
const redshiftRole = new aws.iam.Role("redshiftRole", {
    assumeRolePolicy: JSON.stringify({
        Version: "2012-10-17",
        Statement: [
            {
                Action: "sts:AssumeRole",
                Principal: {
                    Service: "redshift.amazonaws.com",
                },
                Effect: "Allow",
                Sid: ""
            }
        ]
    })
});

// Attach the AmazonRedshiftAllCommandsFullAccess policy to the role
const redshiftPolicyAttachment = new aws.iam.RolePolicyAttachment("redshiftPolicyAttachment", {
    role: redshiftRole.name,
    policyArn: "arn:aws:iam::aws:policy/AmazonRedshiftAllCommandsFullAccess"
});

// Create a Redshift cluster (Producer)
const producerCluster = new aws.redshift.Cluster("producerCluster", {
    clusterIdentifier: "producer-cluster",
    nodeType: "dc2.large",
    masterUsername: "admin",
    masterPassword: "Pulumi1234",
    clusterType: "single-node",
    iamRoles: [redshiftRole.arn],
});

// Create a Redshift cluster (Consumer)
const consumerCluster = new aws.redshift.Cluster("consumerCluster", {
    clusterIdentifier: "consumer-cluster",
    nodeType: "dc2.large",
    masterUsername: "admin",
    masterPassword: "Pulumi1234",
    clusterType: "single-node",
    iamRoles: [redshiftRole.arn],
});

// Export the cluster endpoints
export const producerClusterEndpoint = producerCluster.endpoint;
export const consumerClusterEndpoint = consumerCluster.endpoint;
