Mryange opened a new pull request, #24881:
URL: https://github.com/apache/doris/pull/24881
## Proposed changes
You can set the level of counters on the backend using
ADD_COUNTER_WITH_LEVEL/ADD_TIMER_WITH_LEVEL. The profile can then merge
counters with level 1.
such as
sql
select count(*) from customer join item on c_customer_sk =
i_item_sk
profile
```
