Querying a Day's Worthe Data at Once?

The ordering of this was important to were, like, let's say that you're querying a day's worthe data at once. By doing it this way, by putting the censor name plus the time stamp on the end of it as your he, then you'll be able to run aggregates. But what am i missing here then? Because in that scenario, like, you might as well only have just the censor name. And, like, why do you need the date, like at that point?Because i thought the purpose was to spread it evenly across all the partitions, and that's why you were combining the two.
