How to handle big business data in bonita studio?



I already had a question regarding this matter, but it was more of a the front end side problem.

I have and object (A) and this object has a lot of objects (B list, about 10 000 objects).

What i want to do is manipulate A object, but at the moment i dont need the B objects, i just want to modify the A object.

In the business data definition i have set B to multiple and aggregation with the setting only load when needed.

In bonita studio i created a process that starts with loading the A object in a business variable, but it takes a lot of time, to do so, i think maybe it is loading the whole object with the B object list? But i tought it will only be loaded when i "need it", not always when i try to use it in business data.

Could someone explain this to me? How the only needed and always load settings work? I read about this that the only needed is the lazy loading, and it will only get data from the database when i call it, but it doesnt seem to be the case in bonita.

Overall, how can i handle a business data object that has many objects in it? (like in the case i described)

Thank you!
