Tutorial: Using the Resize Operation to Resize a Cluster

This section walks you through the process of resizing a cluster by using the resize operation in Amazon Redshift. In this example, you’ll scale your cluster out by resizing from a single node cluster to a multinode cluster.

Complete this tutorial by performing the steps in the following:

Prerequisites

Before you start this tutorial, make sure that you have the following prerequisites:

  • A sample cluster. In this example, you’ll start with the sample cluster that you created in the Amazon Redshift Getting Started exercise. If you don't have a sample cluster to use for this tutorial, complete the Getting Started exercise to create one and then return to this tutorial.

Step 1: Resize the Cluster

  1. Open the Amazon Redshift console.

  2. In the navigation pane, click Clusters, and then click the cluster to open. If you are using the same cluster from the Amazon Redshift Getting Started exercise, click examplecluster.

  3. On the Configuration tab of the Cluster details page, click Resize in the Cluster list.

  4. In the Resize Cluster window, select the following values:

    • Node Type: dc1.large.

    • Cluster Type: Multi Node.

    • Number of Nodes: 2.

  5. Click Resize.

  6. Click Status, and review the resize status information to see the resize progress.

Step 2: Delete the Sample Cluster

After you are sure that you no longer need the sample cluster, you can delete it. In a production environment, whether you decide to keep a final snapshot depends on your data policies. In this tutorial, you’ll delete the cluster without a final snapshot because you are using sample data.

Important

You are charged for any clusters until they are deleted.

  1. Open the Amazon Redshift console.

  2. In the navigation pane, click Clusters, and then click the cluster to open. If you are using the same cluster names from this tutorial, click examplecluster.

  3. On the Configuration tab of the Cluster details page, click Delete in the Cluster list.

  4. In the Delete Cluster window, click No for Create final snapshot, and then click Delete.
