ClickHouse | ClickHouse | 727,531,046 | 17,041 | ucasfl | I'm confusing about the specialized implementation of countIf, does it have special optimization? Current implementation is worse maybe, because currently, `select countIf(1) from numbers(1000000000)` is too much slower than `select sum(if(1, 1, 0)) from numbers(1000000000)`. @alexey-milovidov | 2020-11-15T07:57:50 | 2020-11-15T07:57:50 | {} | COLLABORATOR |
