> Now, the implementation of TwoPhaseCommitSinkFunction is based on operator state, but operator state will do a deep copy when taking checkpoint, so large operator state may produce a OOM error. Add support of KeyedState in TwoPhaseCommitSinkFunction maybe a good choice to avoid the OOM error and give users more convenience.
