pyspark.streaming.DStream.fullOuterJoin¶

DStream.fullOuterJoin(other: pyspark.streaming.dstream.DStream[Tuple[K, U]], numPartitions: Optional[int] = None) → pyspark.streaming.dstream.DStream[Tuple[K, Tuple[Optional[V], Optional[U]]]][source]¶

Return a new DStream by applying ‘full outer join’ between RDDs of this DStream and other DStream.

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