<p>A Cross transformation combines the elements of two
{@link DataSet DataSets} into one DataSet. It builds all pair combinations of elements of
both DataSets, i.e., it builds a Cartesian product.
This method also gives the hint to the optimizer that the second DataSet to cross is much
larger than the first one.
<p>The resulting {@link org.apache.flink.api.java.operators.CrossOperator.DefaultCross} wraps each pair of crossed elements into a {@link Tuple2}, with
the element of the first input being the first field of the tuple and the element of the
second input being the second field of the tuple.
<p>Call {@link org.apache.flink.api.java.operators.CrossOperator.DefaultCross#with(org.apache.flink.api.common.functions.CrossFunction)} to define a
{@link org.apache.flink.api.common.functions.CrossFunction} which is called for
each pair of crossed elements. The CrossFunction returns a exactly one element for each pair of input elements.
@param other The other DataSet with which this DataSet is crossed.
@return A DefaultCross that returns a Tuple2 for each pair of crossed elements.

"thr... | Tells this vertex to strictly co locate its subtasks with the subtasks of the given vertex.
Strict co-location implies that the n'th subtask of this vertex will run on the same parallel computing
instance (TaskManager) as the n'th subtask of the given vertex.
NOTE: Co-location is only possible between vertices in a slot sharing group.
NOTE: This vertex must (transitively) depend on the vertex to be co-located with. That means that the
respective vertex must be a (transitive) input of this vertex.
@param strictlyCoLocatedWith The vertex whose subtasks to co-locate this vertex's subtasks with.
@throws IllegalArgumentException Thrown, if this vertex and the vertex to co-locate with are not in a common
slot sharing group.
