Review Comment:
we have the exact same util in pinot-controller that listed out all the
accessed tables --> then find the appropriate broker to route the query to.
however that's based off SqlNode instead of RelNode. I was thinking about
unifying these two later. we can keep a TODO github issue for reminder if we
decided to merge this PR as is
