Answer / Atish Kumar Paswan
"In Apache Spark, transformations create a new DataFrame or RDD and return a new Action object. Transformations are lazy by default, meaning they only execute when an action is triggered. Actions, on the other hand, perform an operation that generates a physical result, such as saving data to a file or counting the number of records in a DataFrame."n
