Overview of this book

Amazon Redshift is a fully managed, petabyte-scale AWS cloud data warehousing service. It enables you to build new data warehouse workloads on AWS and migrate on-premises traditional data warehousing platforms to Redshift. This book on Amazon Redshift starts by focusing on Redshift architecture, showing you how to perform database administration tasks on Redshift. You'll then learn how to optimize your data warehouse to quickly execute complex analytic queries against very large datasets. Because of the massive amount of data involved in data warehousing, designing your database for analytical processing lets you take full advantage of Redshift's columnar architecture and managed services. As you advance, you’ll discover how to deploy fully automated and highly scalable extract, transform, and load (ETL) processes, which help minimize the operational efforts that you have to invest in managing regular ETL pipelines and ensure the timely and accurate refreshing of your data warehouse. Finally, you'll gain a clear understanding of Redshift use cases, data ingestion, data management, security, and scaling so that you can build a scalable data warehouse platform. By the end of this Redshift book, you'll be able to implement a Redshift-based data analytics solution and have understood the best practice solutions to commonly faced problems.

Scheduling Elastic Resizing

Although we've reviewed the on-demand resize operations that satisfy most use cases, there are times when customers are interested in scheduling a resize operation based on their business requirements. For example, you might want to upsize your cluster before starting your scheduled extract, transform and load process to satisfy any SLA needs.

Getting ready

To complete this recipe, you will need the following:

  • An IAM user with access to Amazon Redshift
  • An IAM role, Chapter8RedshiftSchedulerRole, that can schedule elastic resizing for a Redshift cluster
  • An Amazon Redshift cluster deployed in AWS Region eu-west-1

How to do it…

In this recipe, you will learn how to elastic resize the existing Redshift cluster using a schedule:

  1. Open the Amazon Redshift console: https://console.aws.amazon.com/redshiftv2/home.
  2. Select the cluster, click Actions, and select Resize:
