             Summary: Window functions should also allow looking back in time
                 Key: SPARK-17893
                 URL: https://issues.apache.org/jira/browse/SPARK-17893
             Project: Spark
          Issue Type: New Feature
          Components: Spark Core
    Affects Versions: 2.0.1
            Reporter: Raviteja Lokineni

This function should allow looking back. The current window(timestamp, 
duration) seems to be for looking forward in time.

{code}dataFrame.groupBy(window("date", "7 days ago")).agg(min("col1"), 

For example, if date: 2013-01-07 then the window should be 2013-01-01 -
