Spark Intersection Function

In Spark, Intersection function returns a new dataset that contains the intersection of elements present in the different datasets. So, it returns only a single row. This function behaves just like the INTERSECT query in SQL.

Example of Intersection function

In this example, we intersect the elements of two datasets.

• To open the Spark in Scala mode, follow the below command.

• Create an RDD using the parallelized collection.

• Now, we can read the generated result by using the following command.

• Create another RDD using parallelized collection.

• Now, we can read the generated result by using the following command.

• Apply intersection() function to return the intersection of the elements.

• Now, we can read the generated result by using the following command.

Here, we got the desired output.
