    Hi @yestinchen 
    
    Thanks for your feedback. 
    
    Right now, I just want to address the empty match issue. It is not easy to apply that
definition to unbounded data. In the SQL specification at the end of partition we can deterministically
decide if a partial match is empty or not. It is not the case in unbounded data, as future
arriving events may make the partial matches empty. 
    
    Those are the nuances I think should be addressed first, but I agree there are many similarities.
    
    I will try to address rest later during the day, but I think we should continue in the
JIRA.
