> For any UIs that involve pagination, it is useful to issue queries in the
> form SELECT ... LIMIT X,Y where X,Y are coordinates inside the result to be
> paginated (which can be extremely large by itself). At present, ROW_NUMBER
> can be used to achieve this effect, but optimizations for LIMIT such as TopN
> in ReduceSink do not apply to ROW_NUMBER. We can add first class support for
> "skip" to existing limit, or improve ROW_NUMBER for better performance
