   ### Search before asking
   
   - [X] I had searched in the 
[issues](https://github.com/apache/incubator-doris/issues?q=is%3Aissue) and 
found no similar issues.
   
   
   ### Description
   
   In general,`std::move` of the const expression has no effect, but we use it 
to get mutate column now, we can just use assume_mutate to replace `std::move`.
   
   ### Solution
   
   ```cpp
   // std::move
   auto column = 
std::move(*part_key->first->get_by_position(pos).column).mutate();
   // assume_mutable
   auto column = part_key->first->get_by_position(pos).column->assume_mutable();
   ```
