Answer Posted / neetu arora
Dynamic cache is generally used when u are applying lookup
on a target table and in one flow same data is coming twice
for insertion or once for insertion and once for updation.
Performance: dynamic cache decreases the performance in
comparision to static cache since it first looks in the
whole table tht whether data ws previously present if no
thn only it inserts so it takes much tym
Static cache do not see such things just insert data as
many tyms as it is coming.
