pyspark.RDD.cartesian

RDD.cartesian(other: pyspark.rdd.RDD[U]) → pyspark.rdd.RDD[Tuple[T, U]]

Return the Cartesian product of this RDD and another one, that is, the RDD of all pairs of elements (a, b) where a is in self and b is in other.

Examples

>>> rdd = sc.parallelize([1, 2])
>>> sorted(rdd.cartesian(rdd).collect())
[(1, 1), (1, 2), (2, 1), (2, 2)]
