Hello we have heard your product and we will plan to use your product on image database.
Is it good to use ObjectDB as image database?
Image database just screenshots of desktops.
2- ) On JPA as we know getting Result list returns ArrayList
List<SomeClass> xxx = query.getResultList();
Producing everytime ResultList ( Garbage collection destroy and remake ) slows apps i think. I think it will be good if you make object pooling for every class.We dont know about your codes but i think it will be very good if you make object pool.
