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.

Loading delimited bulk data into Snowflake from your local machine

This recipe demonstrates several important concepts related to loading data from an on-premises system to your Snowflake instance. We will make use of the internal stages in Snowflake to load the data from an on-premises system. This system could be a host machine running on your network or your laptop with files to be loaded stored in its storage.

Getting ready

Since we will be loading a file from your local system into Snowflake, we will need to first get such a file ready on the local system. To save time you can download a previously created sample file from https://github.com/PacktPublishing/Snowflake-Cookbook/blob/master/Chapter03/r3/customers.csv.

Now, since we will be loading data from your local system, we will need to use snowsql to upload the file to Snowflake. Please make sure that SnowSQL is installed on your system and you can successfully connect to your Snowflake instance.
