clintropolis opened a new pull request, #18512:
URL: https://github.com/apache/druid/pull/18512
### Description
Following up on #18507, which vectorized `if`, this PR vectorizes
`case_searched`, which is a pretty nice perf improvement:
```
SELECT CASE WHEN MOD(long1, 2) = 0 THEN -1 WHEN MOD(long1, 2) = 1 THEN long2
/ MOD(long1, 2) ELSE long3 END FROM expressions GROUP BY 1
