> StreamTask support efficient object reuse. The purpose behind this is to reduce pressure on the garbage collector.
> All objects are reused, without backup copies. The operators and UDFs must be careful to not keep any objects as state or not to modify the objects.
> *FYI, now this thread is blocked by FLIP-21. The pull request attached is closed for a needed rework.*
