Hi,
say I have one instance to delete, an instance of B knowing that A
contains one to many B.
Should I merge A with one less B, that should delete the required B
or should I explicitly delete that B with a delete by query or
should I use the remove(thatB) API ?
What are the differences in term of design, memory, performance, ... ?
Quedtion also apply in case of a new B : merge on A, insert by query
or persist(thatB) on entityManager ?
The same question apply to merge or update by query one B.
Thanks !
