Review comment:
       v2 places `dst_tbl` directly to the catalog:
   ```
         sql(s"SHOW TABLES IN $catalog").show(false)
   
   +---------+---------+-----------+
   |namespace|tableName|isTemporary|
   +---------+---------+-----------+
   |         |dst_tbl  |false      |
   +---------+---------+-----------+
   ```
   but v1 to the same namespace:
   ```
   +---------+---------+-----------+
   |namespace|tableName|isTemporary|
   +---------+---------+-----------+
   |ns       |dst_tbl  |false      |
   +---------+---------+-----------+
   ```
