Why?
It would be surprising to me if, given that we have gone to some pains
to create a system that allows cross-system queries, and hopefully
eventually pushdown of quals, joins, and aggregates, we then made
sharding work in some completely different way that reuses none of
that infrastructure. But maybe I am looking at this the wrong way.
