Cluster

The Cluster resource lets you manage AWS Redshift Clusters which are designed for data warehousing and analytics. You can create and configure clusters with various properties including node type, number of nodes, and security settings.

Minimal Example

Create a basic AWS Redshift Cluster with required properties and a few common optional ones.

import AWS from "alchemy/aws/control";

const redshiftCluster = await AWS.Redshift.Cluster("myRedshiftCluster", {
  nodeType: "dc2.large",
  clusterType: "single-node",
  dbName: "analyticsdb",
  masterUsername: "admin",
  masterUserPassword: "SecurePass123!",
  port: 5439,
  tags: [
    {
      Key: "Environment",
      Value: "Development"
    }
  ]
});

Advanced Configuration

Configure a Redshift Cluster with additional settings for enhanced security and maintenance.

const advancedRedshiftCluster = await AWS.Redshift.Cluster("advancedRedshiftCluster", {
  nodeType: "dc2.8xlarge",
  clusterType: "multi-node",
  dbName: "productiondb",
  masterUsername: "admin",
  masterUserPassword: "SecurePass123!",
  port: 5439,
  multiAZ: true,
  encrypted: true,
  automatedSnapshotRetentionPeriod: 7,
  preferredMaintenanceWindow: "sun:06:00-sun:06:30",
  iamRoles: ["arn:aws:iam::123456789012:role/MyRedshiftRole"],
  clusterParameterGroupName: "default.redshift-1.0",
  vpcSecurityGroupIds: ["sg-0123456789abcdef0"]
});

Using Snapshot Copy

Create a cluster that uses snapshot copy for disaster recovery.

const snapshotCopyCluster = await AWS.Redshift.Cluster("snapshotCopyCluster", {
  nodeType: "dc2.large",
  clusterType: "single-node",
  dbName: "backupdb",
  masterUsername: "admin",
  masterUserPassword: "SecurePass123!",
  port: 5439,
  snapshotCopyRetentionPeriod: 30,
  snapshotCopyManual: true,
  destinationRegion: "us-west-2"
});

Defer Maintenance

Configure a Redshift Cluster with deferred maintenance settings.

const maintenanceCluster = await AWS.Redshift.Cluster("maintenanceCluster", {
  nodeType: "dc2.large",
  clusterType: "single-node",
  dbName: "maintenanceDB",
  masterUsername: "admin",
  masterUserPassword: "SecurePass123!",
  port: 5439,
  deferMaintenance: true,
  deferMaintenanceStartTime: "2023-11-01T00:00:00Z",
  deferMaintenanceDuration: 30 // Duration in minutes
});
