Overview of this book

Snowflake is a unique cloud-based data warehousing platform built from scratch to perform data management on the cloud. This book introduces you to Snowflake's unique architecture, which places it at the forefront of cloud data warehouses. You'll explore the compute model available with Snowflake, and find out how Snowflake allows extensive scaling through the virtual warehouses. You will then learn how to configure a virtual warehouse for optimizing cost and performance. Moving on, you'll get to grips with the data ecosystem and discover how Snowflake integrates with other technologies for staging and loading data. As you progress through the chapters, you will leverage Snowflake's capabilities to process a series of SQL statements using tasks to build data pipelines and find out how you can create modern data solutions and pipelines designed to provide high performance and scalability. You will also get to grips with creating role hierarchies, adding custom roles, and setting default roles for users before covering advanced topics such as data sharing, cloning, and performance optimization. By the end of this Snowflake book, you will be well-versed in Snowflake's architecture for building modern analytical solutions and understand best practices for solving commonly faced problems using practical recipes.

Creating a tailored multi-cluster virtual warehouse

While creating a standard virtual warehouse is a straightforward affair, configuring a virtual warehouse that the standard options have been customized for can be a slightly more involved process. In this recipe, we will create a new multi-cluster virtual warehouse and set the scaling configuration so that the virtual warehouse can scale up and down on demand. We will also configure some advanced parameters to allow a higher number of concurrent queries to be executed.

Getting ready

To create a multi-cluster virtual warehouse, you must have the Enterprise or higher edition of Snowflake. If you run the following statements on a lower edition, you will likely receive an error stating 'MULTI_CLUSTER_WAREHOUSES' not enabled. Your user should have the SYSADMIN role or higher since the SYSADMIN (or the even higher ACCOUNTADMIN) role can create a virtual warehouse.
