/**
 * Initiates a Join transformation.
 *
 * <p>A Join transformation joins the elements of two
 *   {@link DataSet DataSets} on key equality and provides multiple ways to combine
 *   joining elements into one DataSet.
 *
 * <p>This method also gives the hint to the optimizer that the second DataSet to join is much
 *   larger than the first one.
 *
 * <p>This method returns a {@link JoinOperatorSets} on which one of the {@code where} methods
 * can be called to define the join key of the first joining (i.e., this) DataSet.
 *
 * @param other The other DataSet with which this DataSet is joined.
 * @return A JoinOperatorSet to continue the definition of the Join transformation.
