{"Action": "An action causes the RDD to be computed (i.e., evaluated) and the result of the computation is materialized. Actions are blocking operations, meaning they wait for all tasks related to the computation to complete before returning a final result."n"result": "The final result is generated using an action by triggering it on an RDD or DStream. The returned value represents the aggregated output of the specified transformation(s) on the input dataset.""}
