Assume I have two class A and B, which is unidirection unowned many to one relationship. (A * ----> 1 B) I store the Key of class B inside class A. The code looks like this, (I am using JPA)
@Entity public class A { @Enumerated private Key bKey; } @Entity public class B { } Both A and B instance of the same user are under the same entity group. When I need to delete B, lets say 'Bx' any A that associate with 'Bx' is going to change the association to 'By'. I can do this by query and iterate update with low level API. However, there might be a huge amount of A, This will exceed the request time limit. What's the best solution to solve this problem? Thanks!!
