      Description

      Right now stream JOIN is supported in syntax (e.g. in planner), however, there are more areas needs a enhancement:
      1. Does windowing strategy in JOIN have a constraint? For example, is a TUMBLE stream allowed to join a HOP stream?
      2. If there is any constraints on windowing strategy in JOIN, how will that affect JOIN reordering?
      3. How to optimize stream join stream or stream join table, which, by nature, should be different from table join table?
