   Well, you mean that I created the vertical table directly in "mysql" when I created it; but when I used it, I used it in "sharding" because "sharding" can find out where it is.
   
   However, we don't want anyone to be able to connect directly to the mysql below. This is a very dangerous thing. All user operations can only go through "sharding".
