Review comment:
Just an idea, not sure if this is too specific.
```java
public interface RecordWriterDelegate<OUT> extends AvailabilityProvider,
AutoCloseable {
RecordWriter<SerializationDelegate<StreamRecord<OUT>>>
getRecordWriter(int outputIndex);
}
```
Then the signature of the Operator ctor would be
```java
public OperatorChain(
StreamTask<OUT, OP> containingTask,
RecordWriterDelegate<OUT> recordWriters) {
```
