Answer / Ajay Kumar Dewabansi
Transformation operations in Spark return a new DataFrame/RDD without triggering physical execution. They can be chained together and only an action operation triggers the actual data processing. Examples of transformations include map, filter, and groupBy. An example of an action is count.
