Review comment:
I took a deeper look and realized that we only need subtaskIndex:
```
@Override
public Integer map(Integer value) throws Exception {
// Allow working only one last subtask until the checkpoint
barrier reaches the sink.
if (getRuntimeContext().getIndexOfThisSubtask() > 0) {
```
and don't need neither `idGenerator` nor `subtaskMapId`.
