Hi:
  As  the following sql:

   SELECT *  FROM Orders INNER JOIN Product ON Orders.productId = Product.id

 If we use datastream API instead  of sql, how should it be achieved?
 Because the APIs in DataStream only have Window Join and Interval Join,the
official website says that to solve the above state capacity problem in sql
is using TableConfig. But TableConfig itself can only solve the state  ttl
problem of non-time operators. So I think the above sql's  implementation
is neither tumble window join, nor sliding window join and interval join.
