# Opening the PDI step Spark tuning options

You can access Spark tuning from a PDI step by right-clicking on the step in the canvas and selecting Spark tuning from the menu. The Spark tuning parameters dialog box appears. Only the Spark tuning options available for that step appear in the dialog box. These options vary step-to-step, depending on the scope of the step.

See [Spark Tuning](/install/9.3-install/pentaho-configuration/tasks-to-be-performed-by-an-it-administrator/set-up-the-adaptive-execution-layer-ael/advanced-topics/spark-tuning-landing-page-cp.md) for more information.
