Hi Fabian,
        SELECT article_id FROM praise GROUP BY article_id having count(1)>=10
        If article_id 123 has 100 praises and remains its state in the dynamic 
table ,and when the time passed, its state is removed, but later the article_id 
123 has never reached to 10 praises.
        How can other program know that the state is been removed? Because the 
sink currently has the praises count stored as 100, it is not consistent as the 
dynamic table.

Best, 
Henry
