Name the operations supported by RDD?

As the major logical data units in Apache Spark, RDD possesses a distributed collection of data. It is a read-only data structure and you cannot change the original format but it can always be transformed into a different form with the changes. The two operations which are supported by RDD are -

• Transformation - It creates a new RDD from the former one. They are executed only on demand.
• Actions - The final outcomes of the RDD computations are returned by actions.
