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.

Managing transactions in Snowflake

Snowflake is an ACID-compliant database system. ACID is an acronym for atomicity, consistency, isolation, and durability, a set of properties for database transactions that ensure that the data in a database remains valid during operations that change the data, regardless of errors and failures. This recipe will provide you with insights into how to use transactions in Snowflake. The different concepts around isolation will be covered in this recipe. Snowflake's limitations will also be explained, particularly around the scope of a transaction, how commits and rollbacks work, and how the session is important in managing transaction behavior.

Getting ready

Note that this recipe's steps can be run either in the Snowflake WebUI or the SnowSQL command-line client.

How to do it…

The recipe will start by introducing Snowflake constructs for enabling transactions. We shall investigate how transactions can be started, as well...
