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.

Delineating user management from security and role management

In this recipe, we will be using Snowflake's built-in roles to isolate access for operational teams that create users and roles and security teams that manage and control the access rights. The USERADMIN Snowflake role provides privileges for creating and managing users without requiring a higher privilege as with SECURITYADMIN. Therefore, the USERADMIN role can be granted to the operations team responsible for onboarding and offboarding users to your Snowflake instance.

Getting ready

Before proceeding with this recipe, please ensure that the user you will modify can use the SECURITYADMIN role. Note that this recipe's steps can be run in either the Snowflake web UI or the SnowSQL command-line client.

How to do it…

We will create a new user to whom we will grant the USERADMIN role:

  1. Create a new database that will be used to demonstrate privilege management:
    USE ROLE SYSADMIN;
    CREATE DATABASE...
