# Spark SDK

In addition to its native integration with Databricks, Tonic Structural also supports Spark through an SDK.

The Spark SDK allows you to incorporate Structural directly into existing Spark programs and workflows.

The Structural Spark SDK is written in Java. It can be used in existing Java, PySpark, and Scala Spark programs.
