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.

Connecting to an Amazon Redshift cluster using the Query Editor

The Query Editor is a thin client browser-based interface available on the AWS Management Console for running SQL queries on Amazon Redshift clusters directly. Once you have created the cluster, you can use the Query Editor to jumpstart querying the cluster without needing to set up the JDBC/ODBC driver. This recipe will show you how get started with the Query Editor so that you can access your Redshift clusters.

The Query Editor allows you to do the following:

  • Explore the schema
  • Run multiple DDL and DML SQL commands
  • Run single/multiple select statements
  • View query execution details
  • Save a query
  • Download a query result set that's up to 100 MB in size in a .CSV, text, or HTML file

Getting ready
