When you run mappings in the native environment, the Data Integration Service processes the mapping and runs the mapping from the Developer tool.

When you select the Hadoop environment, the Data Integration Service pushes the mapping to a compute cluster and processes the mapping on a Spark engine. The Data Integration Service generates an execution plan to run mappings on the Spark engine.

When you run mappings in the Databricks environment, the Integration Service pushes the mapping logic to the Databricks Spark engine, the Apache Spark engine packaged for Databricks.

You can view the plan in the Developer tool before you run the mapping and in the Administrator tool after you run the mapping.

For more information about the non-native environment, see the

Data Engineering Administrator Guide
