I am a little confused about the method pyspark.sql.Window.rowsBetween that accepts Window.unboundedPreceding, Window.unboundedFollowing, and Window.currentRow objects as start and end arguments. Could you please explain how the function works and how to use Window objects correctly, with some examples? Thank you!
