Answer: No rollback occurs; any completed operations, such as writes to disk or Delta table before `clean_data` failed, remain unchanged.
Correct. In Databricks, if a task fails, there is no automatic rollback of completed operations. Any writes or changes made before the failure remain intact. Dependent tasks may or may not run, depending on the job's configuration, but the scenario specifies they still needed to be run, implying they would proceed if possible.
