The clean fix would be to support multiple arguments for `DistinctCount` function family, or model this query as `COUNT` over distinct query. Using `CONCAT` can be a temporary work-around, but it is suboptimal for: - Only can handle 2 arguments case - Not efficient for non-string columns - Not efficient because it is a scalar function We might be able to provide a transform function to combine multiple values more efficiently.
