Answer / Anoop Dwivedi
"Transformations in Apache Spark RDDs create new RDDs from existing ones by applying various operations like map(), filter(), groupByKey(), etc. They are lazy evaluations, meaning they do not execute until an action is triggered. Actions on the other hand, compute a result and return a value, such as count(), collect(), saveAsTextFile(), etc."
