If you are a data engineer, data analyst, or developer already using Snowflake, then you might have heard of the term \u201cSnowpark\u201d. But do you understand the term completely? Read this article to understand what Snowpark is, how to implement it, examples of its usage, and further information on this functionality.<\/p>\n\n\n\n

What Is a Snowpark? <\/h2>\n\n\n\n

Snowpark is a set of libraries and runtimes that lets teams build data pipelines, applications, and machine learning workflows in Snowflake.  Instead of writing everything in SQL language, you can use programming languages such as Java, Python, and Scala and work with data directly inside Snowflake. <\/p>\n\n\n\n

Why Does It Matter?<\/h3>\n\n\n\n

Snowpark handles data processing inside Snowflake, which reduces the need to export large datasets.<\/p>\n\n\n\n

Earlier, working with data meant moving it out of Snowflake<\/a>. You’d send it to another tool, server, or Spark cluster. Then you would run your code there and move the results back again. While this worked, it added more steps, infrastructure, and things to manage for users.<\/p>\n\n\n\n

Snowpark removes all this by allowing your code to run inside Snowflake’s engine. <\/p>\n\n\n\n

How Does Snowpark Architecture Work?<\/h2>\n\n\n\n

Snowpark architecture works in layers. You write code locally, Snowpark builds a plan, and Snowflake developers<\/a> execute it on your data without moving anything.<\/p>\n\n\n\n

The Client Libraries<\/h3>\n\n\n\n

This is where you write your code. Snowpark gives you libraries for Python, Java, and Scala. You write a script on your laptop or in a notebook, just like you normally would.<\/p>\n\n\n\n

DataFrames<\/h3>\n\n\n\n

When you write code using Snowpark, you work with a DataFrame<\/strong>. Think of it like a spreadsheet in code form with rows, columns, filters, transformations. Snowpark also supports a familiar pandas API<\/strong>, so if you’re already a Python user, you’re mostly at home.<\/p>\n\n\n\n

The Lazy Evaluation Engine<\/h3>\n\n\n\n

Here’s something interesting about Snowpark architecture. It doesn’t run your code the moment you write it. It waits. Instead of running every command right away, Snowpark first creates a plan for what needs to happen. The actual processing only starts when you request the final result. This approach, called lazy evaluation, gives Snowflake time to optimize the work before it touches your data.<\/p>\n\n\n\n

Execution Inside Snowflake<\/h3>\n\n\n\n

Your code runs inside Snowflake\u2019s engine, not on your laptop or any other third-party server. This means that your data stays where it is, while Snowflake handles all the processing. <\/p>\n\n\n\n

User-Defined Functions (UDFs) and Stored Procedures<\/h3>\n\n\n\n

You can create custom functions and stored procedures using languages like Python, Java, or Scala. After you add these to Snowflake, they can be executed directly through SQL commands. This is similar to built-in functions.<\/p>\n\n\n
