Snowpark Developer Guide for Java¶
The Snowpark library provides an intuitive API for querying and processing data in a data pipeline. Using the Snowpark library, you can build applications that process data in Snowflake without moving data to the system where your application code runs.
For an introduction to Snowpark, see Snowpark API.
Get Started¶
- Setting Up Your Development Environment for Snowpark Java
Set up to build Snowpark apps using any of several development environments.
