ParallelGroupedMerge (flink-streaming-core 0.9.1-hadoop1 API)

java.lang.Object
- org.apache.flink.api.common.functions.AbstractRichFunction
- - org.apache.flink.streaming.api.functions.co.RichCoFlatMapFunction<StreamWindow<OUT>,org.apache.flink.api.java.tuple.Tuple2<Integer,Integer>,StreamWindow<OUT>>
  - - org.apache.flink.streaming.api.operators.windowing.ParallelMerge<OUT>
    - - org.apache.flink.streaming.api.operators.windowing.ParallelGroupedMerge<OUT>

All Implemented Interfaces:

Serializable, org.apache.flink.api.common.functions.Function, org.apache.flink.api.common.functions.RichFunction, CoFlatMapFunction<StreamWindow<OUT>,org.apache.flink.api.java.tuple.Tuple2<Integer,Integer>,StreamWindow<OUT>>
```
public class ParallelGroupedMerge<OUT>
extends ParallelMerge<OUT>
```
The version of the ParallelMerge CoFlatMap that does not reduce the incoming elements only appends them to the current window. This is necessary for grouped reduces.
