hi all, quick question: is it possible to set up partitions on more than a single axis?

Yes. However, partition sets take flat lists. If you enumerate your grid and map each point in that space to a "human readable" partition, you can pass a list of numbers which represent a combinatorial explosion of your partitions and generate the human readable string when you need assuming you have that lookup lying around somewhere in your code.

@sashank has thought a lot about this

We’re trying to figure out the best way to support this so would love to hear your thoughts

Well, for my use-case, being able to define multiple partition sets and their ordering (or hierarchy if you will) would work
