zeroflag opened a new pull request #2390:
URL: https://github.com/apache/hive/pull/2390
If hive.vectorized.adaptor.usage.mode is set to chosen only certain UDFS are
vectorized through the vectorized adaptor.
Queries like this one, performs very slowly because the concat is not chosen
to be vectorized.
```
select count(*) from tbl where to_date(concat(year, '-', month, '-', day))
between to_date('2018-12-01') and to_date('2021-03-01');
```
