event-time semantics
                 Key: BEAM-12131
                 URL: https://issues.apache.org/jira/browse/BEAM-12131

          Issue Type: Improvement
          Components: sdk-py-core
            Reporter: Brian Hulette


pandas has support for 
[rolling()|https://pandas.pydata.org/pandas-docs/stable/user_guide/window.html] 
windows. It should be possible to use this within a DataframeTransform and have 
it apply Beam windowing.
