Jibing-Li opened a new pull request, #23393:
URL: https://github.com/apache/doris/pull/23393
The sql like
```Select count(1) from view ```
would contain all the columns in old planner's execution plan, which is
slow, because BE need to read all the column in data files. This pr is to
improve the plan to only contain one column.
