Previously we processed our metrics by consolidating them into multidimensional entries on a minute basis.

We moved to single metric second-based collection, because it was getting too complicated to process and because we wanted second-by-second measurement to measure engagement more granularly. That increased our data retention tremendously. We're still under the cost for the other timestream products, but we'll be adjusting how we do that in a quarter or two.

I've always made the assumption that once they become "not cheap" you now have the cost to offset investment against.
