Selected Answer: AB

Why the others are incorrect: • C. Create index on filtered column (❌) • This affects query execution time in the database, not the transform phase in Appian. • D. Lower the batch size (❌) • This affects memory consumption and possibly performance, but it typically results in more round trips and doesn’t directly reduce transform time.
