pyspark.streaming.DStream.cogroup

DStream.cogroup(other: pyspark.streaming.dstream.DStream[Tuple[K, U]], numPartitions: Optional[int] = None) → pyspark.streaming.dstream.DStream[Tuple[K, Tuple[pyspark.resultiterable.ResultIterable[V], pyspark.resultiterable.ResultIterable[U]]]]

Return a new DStream by applying ���cogroup��� between RDDs of this DStream and other DStream.

Hash partitioning is used to generate the RDDs with numPartitions partitions.
