   Hi, it seems that this change breaks the backward compatibility?
   
   Let's say we have 3 time series: root.sg.d.s1, root.sg.d.s2, and root.sg.d.t.s1.
   
   Before this change, the following query produces a result set that contains all of the time series.
   ```
   select * from root.sg.d
   ```
   
   After this change, it produces only root.sg.d.s1 and root.sg.d.s2, right?
