> Currently when checking whether two sides of a Storage Partitioned Join are
> compatible, we requires both the partition expressions as well as the
> partition keys are compatible. However, this condition could be relaxed so
> that we only require the former. In the case that the latter is not
> compatible, we can calculate a common superset of keys and push down the
> information to both sides of the join, and use empty partitions for the
> missing keys.
