> Currently we can merge 2-way joins into n-way joins when the joins are
> executed over the same column.
> In turn, CBO might produce plans containing cartesian products if the join
> columns are constant values; after HIVE-12543 went in, this is rather common,
> as those constant columns are correctly pruned. However, currently we do not
> merge a cartesian product with two inputs into a cartesian product with
> multiple inputs, which could result in performance loss.
