   > Can you explain in what scenario `MutableSnapshot` is needed ? Since it's not supported in SubstitutionVisitor at this moment.
   
   i think it should be supported.
   such as:
   query:
   `SELECT * FROM emps FOR SYSTEM_TIME AS OF TIMESTAMP '2019-12-30 12:34:56'`
   mv:
   `SELECT * FROM emps FOR SYSTEM_TIME AS OF TIMESTAMP '2019-12-30 12:34:56'`
   
   in this case, it should be matched. How do you think ？
