yes but you are not following Michele's advice. If you cache a record
or a an object like a reference, you are storing in ram of copy db
(the leak). You should cache values or dictionaries. As long as those
values are not reference fields there should be no leaks.
I am not sure the term leak is appropriate here. When you cache you
store something and storage takes space, until you clear cache. The
bigger the object you cache, the more space it takes.
