Instead of `ds %>% left_join(dep,by=c("DR"="DEP"))` can you do `dep %>%
right_join(ds,by=c("DEP"="DR"))`?
Typically you want the small table to be the build side (in Acero the second
input is the build side). From the plan it appears that `ds` is the build side
which is bad. Switching from a left to a right join should swap sides. If it
still doesn't work can you share the resulting `explain()` with the right join?
