🛠️ Master the creation and management of Dynamic Tables in Snowflake.
Welcome to this tutorial on Dynamic Tables within Snowflake! This tutorial is designed to help you understand and implement Dynamic Tables in your Snowflake environment. By the end of this tutorial, you'll be able to confidently use this feature to enhance your data processing capabilities and create fast, reliable and enterprise-grade ETL pipelines. So, let's dive in! 🏊♀️
Dynamic Tables are powerful object within Snowflake that allows you to declare a table, based on other tables and using the LAG argument refresh data on schedule. They can be used for a variety of purposes, from data loading and transformation, to analysis and reporting.
Creating a Dynamic Table is achieved using the CREATE OR REPLACE DYNAMIC TABLE command. To ensure that the Dynamic Table runs consistently, we use a WAREHOUSE argument to declare a dedicated warehouse resource for Dynamic Table Operations (even your whole ETL/ELT process).
You are able to manage Dynamic Tables easily using commands such as ALTER DYNAMIC TABLE [ <name> ] { SUSPEND | RESUME }, manually refresh data through using ALTER DYNAMIC TABLE [ <name> ] REFRESH and even chain refreshing based on the conditions of other tables (dynamic or not) downstream using the [ TARGET_LAG = { '<num> { seconds | minutes | hours | days }' | DOWNSTREAM } ].
To use Dynamic Tables within Snowflake, there is a need for a dedicated warehouse resource, and is based on the user-managed compute model, where you specify an existing virtual warehouse.
In this tutorial, we’ll be exploring how to construct a database, schema, and table within Snowflake. We’ll also delve into creating a collection of Dynamic Tables, and implementing the concept of STAR Schema data modelling based off of the data.
By the end of this tutorial, you’ll have gained a comprehensive understanding of how to leverage one of Snowflake’s newest features to efficiently create a ETL/ELT pipeline, with minimal effort.
In conclusion, Dynamic Tables are a powerful feature now available through Public Preview, with the ability to create objects that refresh without the need for additional objects such as stored procedures or tasks. Dynamic Tables provide Engineers and Citizen Developers a new tool in their arsenal to transform data within the Snowflake platform.
