Yeah, that is what it seems like.

Using a column store and doing a bunch of pre-aggregation is the only way we've been able to to come close to these requirements, but I keep hoping there is a system that will do what we've done without having to write code. Trading space for computation is the only thing that has worked reliably.

We also have the benefit that most queries just want a small subset of time and have things sorted to take advantage of that. But occasionally people want to do something over a large range and if isn't a set of group-bys we've pre-aggregated then they just have to be patient.
