Yes, we would probably use a space-filling curve to convert from 3D, just like the current scheme uses a Hilbert curve from 2D. There are some practical performance challenges when the (sparse) tree gets deeper, as I…
CockroachDB does not yet support 3D shapes or indexing. We've discussed extending it to 3D, and you are correct that S2 does not support 3D. S2 was a very convenient starting point for us, but we use a small subset of…
