Suppose you want to compute r⟕r._A=s.A s.

a. Suppose s is a small relation, while r is stored partitioned on r.B. Give an efficient parallel algorithm for computing the left outer join.

b. Now suppose that r is a small relation, and s is a large relation, stored partitioned on attribute s.B. Give an efficient parallel algorithm for computing the above left outer join.
