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.

Setting up development, testing, pre-production, and production database hierarchies and roles

This recipe will walk you through the setup of different environments, such as development, testing, pre-production and production databases, and schemas, and configuring custom roles for managing access.

Getting ready

Before proceeding with this recipe, please ensure that the user you will use 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 demonstrate the creation of development and production databases, roles, and users. The same concept can be extended if other environments are needed:

  1. Let's start by creating a new user who will act as a DBA for the development environment:
    CREATE USER dev_dba_1
    PASSWORD = 'password123' 

    The user is created with a success...
