----------------------------------------------------------------
Update/Delete can certainly write many partitions at the same time, e.g.
Update T set c1=c1+1 where c2 > 100.
This may match 1 row in each partition and thus the Insert statement that is
actually executed will write to each partition. Same for Delete.
Since what is actually executed is an Insert statement, why is Update/Delete
different from any other Insert?
