            Assignee: 陈梓立
             Fix For: 1.7.0


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.
