      Description

      Window TVF would support SESSION window in the following case:

      1. SESSION Window TVF followed by Window Aggregate, in this case SESSION window TVF would be pulled up into WindowAggregate, so Window assigner would happen in WindowAggrgeate  

       

      Note, SESSION window TVF only works in limited cases currently, the following user cases is not supported yet:

      1. SESSION WINDOW TVF followed by Window JOIN
      2. SESSION WINDOW TVF followed by Window RANK**

      BESIDES, SESSION window Aggregate does not support the following performance improvement yet:

           1. Split Distinct Aggregation

           2. Local-global Aggregation

           3. Mini-batch Aggregate
