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.

Connecting to Snowflake with JDBC

The previous recipe talked about using SnowSQL to connect to Snowflake, which provides more control over how a user can interact with Snowflake. SnowSQL can be used with the Linux shell to automate code execution. But if applications have to be supported with Snowflake serving as a data tier, it will require more granular control over connecting and executing SQL. This recipe demonstrates how to install Snowflake's Java Database Connectivity (JDBC) driver and how to use that in a Java application to connect to a Snowflake instance. This functionality is captured in a Java app.

Getting ready

Ubuntu Linux 64-bit has been used for this recipe. The JDBC driver will be downloaded in the home directory of the sfuser user on a 64-bit Linux host called sfchost. These names have no significance and are abbreviations of the Snowflake user and Snowflake client host. Any Linux shell commands shown will be preceded by a sfcuser@sfchost:~$, prompt, though...
