Somehow FILTER is 2x slower on my datasource. I tried these two:
```
select "camp",
sum(cnt+1) filter (where __time >= '2024-06-01' and __time < '2024-06-07')
p,
sum(cnt) filter (where __time >= '2024-06-07' and __time < '2024-06-14') n,
sum(cnt) filter (where __time >= '2024-06-07' and __time < '2024-06-14') -
sum(cnt) filter (where __time >= '2024-06-01' and __time < '2024-06-07') delta
from
atd_pba where __time >= '2024-06-01' and __time < '2024-06-14'
group by 1
order by delta
limit 10
```
```
select p."ucomp", any_value(p.c), any_value(n.c), any_value(n.c- p.c ) delta
from (
select "ucomp" , sum(cnt) c from atd_pba where __time >= '2024-06-01'
and __time < '2024-06-07' group by ucomp
) p
left join
(
select "ucomp" , sum(cnt) c from atd_pba where __time >= '2024-06-07'
and __time < '2024-06-14' group by ucomp
) n
on p.ucomp is not distinct from n.ucomp
group by 1
order by delta
limit 10
```
